A Zuiko 50mm f1.8 on a Sony A7R

In the last of this series of mini-tests of OM Zuiko lenses on an A7R, the very humble 50mm f1.8 is under scrutiny this time. This one came ‘free’ with a second-hand OM2N a few years ago and until now hasn’t been used – my usual 50mm lens choice is my 50mm f1.4 which I’ve used for 34 years (a good investment!).

Zuiko 50mm f1.8, Sony A7R

Bokeh wide open close up.

These were made in their tens (if not hundreds) of thousands by Olympus, being the ‘standard’ lens on OM series cameras for many years. They were slowly improved over three decades (1972 – 2002) gaining multi coating and improved designs and are often overlooked due to their cheapness, humble appearance and the fact that they were the ‘kit lens’ of their day. Let’s have a look.

Zuiko 50mm f1.8, Sony A7R

From above, tiny, light and very portable.

As you’d expect it’s of all metal construction, light (160g or 6 oz), around 3cm long, min focus is around 40cm, apertures run from f1.8 to f16 and it takes 49mm filters – all standard stuff and typical of what makes OM Zuikos so attractive to use.

Zuiko 50mm f1.8, Sony A7R

This is an ‘F Zuiko’ marked lens (meaning six elements) – it doesn’t help date it though (unless you know different!).

Everything on this mid-period still works smoothly, the focus mechanism is smooth and nicely geared though this version of the lens doesn’t appear to be multi coated. There are unfortunately only six aperture blades – eight would be better for out of focus highlights.

Zuiko 50mm f1.8, Sony A7R, Arcangel

Personally I shoot a lot at 50mm – just familiarity I suppose, and the fact that most of my book cover stuff looks natural and undistorted at this focal length.

Zuiko 50mm f1.8, Sony A7R, Arcangel

Depth of field at f1.8 is minimal as you’d expect. Here you can see some of those out of focus highlights have a bright outer rim which can look quite distracting in some shots especially if the highlights are many and close together. I think it’s quite attractive – it’s definitely different to the Zuiko 50mm f1.4’s very soft mushy bokeh – but you may not! It may not be a ‘problem’ with later versions of the lens so don’t let it put you off.

Here are a few more shots to illustrate the bokeh.

Enough about the performance wide open – where some sharpness is sacrificed for subject isolation – how about its performance at f8 (the theoretical optimal aperture for  edge to edge sharpness)?

Zuiko 50mm f1.8, Sony A7R, Arcangel

Pin sharp at f8

Pixel peeping this it looks very good! No chromatic aberration, edges very sharp and no distortion.

Zuiko 50mm f1.8, Sony A7R, Arcangel

At f2.8 sharpness picks up quickly and keeps a shallow depth of field.

So – with a hint of excitement – a proper test across apertures.

At f1.8 it’s quite hazy and soft with some chromatic aberration and a slight amount of vignetting, but by f4 the centre is excellent and by f8 it’s excellent across the whole frame. By f16 – as always – things are going downhill again.

Using old prime lenses on a 36Mp full frame sensor is always going to push them to their limits and means putting up with some corner softness or chromatic aberration. This lens at f8 though does – amazingly – get very close to using all of that sensor resolution across the frame with no nasty side effects. Despite being single coated, I haven’t seen any flare problems either, but I have been using a lens hood during a mainly cloudy late summer. The only oddity is those bright edged out of focus highlights at maximum aperture which I like anyway!

I have to say it’s better in the corners than the other OM 50’s tested so far (my much-loved 1.4 and the 3.5 macro), f1.8 is only slightly slower than f1.4, so I’ll go as far to say to any A7R user – just get one! At £30 it’s the best value lens you’ll find. Later versions of the lens are reputed to be even better!

Watermarked shots have been post processed and have been accepted by my rather picky agency Arcangel in case you were wondering.

Ultrawide on a 5d Mk2 – a Vivitar 17mm f3.5

This lens worked out pretty well on a Canon 60D crop frame sensor (here) and it’s also quite handy on Olympus OM series film cameras. ‘Full Frame’ digital though is a lot more demanding, especially at the far edges of the frame so how well does this vintage lens shape up on the mighty 5D Mk2? I need a wide-angle lens for this camera so it’s been dusted off for a test. All shot in RAW and converted in DXO Optics 9.

Vivitar 17mm f3.5 Canon 5d Mk2

The waterfall at Kimmeridge Bay in full flow. The flare to the bottom left is a ‘feature’ of this lens – I quite like it and here it fills a dark area of the frame.

On the bulky 5d Mk2 even this relatively heavy old MF lens feels fine. It’s lighter than a 24-105mm ‘L’ so it’s quite reasonable to carry around without becoming fatigued. The filter size is 67mm and infinity to minimum focus (25cm) takes a rack of around 180 degrees. The majority of this rack is taken getting from one metre to 25cm so you probably won’t see that bit of the scale very often.

This lens seems to cause the 5D MK2 more metering problems than any lens I’ve attached to it. Evaluative and centre weighted modes both occasionally produced wildly overexposed shots so keep an eye on the playback histogram after each shot.

Vivitar 17mm f3.5 Canon 5d Mk2

On the 5d Mk2 via an Olympus OM to Canon EF Fotodiox adaptor. Nicely balanced and a pleasure to use. Manual focus is very difficult due to the huge depth of field so the LCD of depth of field scale are preferable.

One of the traditional uses of such a wide-angle lens is for course landscapes and initial impressions are impressive at f8. The colours are natural and everything looks sharp enough – without pixel peeping.

Vivitar 17mm f3.5 Canon 5d Mk2

What it should do well – and it does. There isn’t much curvature on horizons (pincushion distortion) as long as the horizon is near the centre of the frame though it’s not that bad generally.

The other traditional use is interior shots and with an angle of view of 90 degrees it’s quite good at that too!

Vivitar 17mm f3.5 Canon 5d Mk2

Remarkably I haven’t seen any chromatic aberration which usually plagues wide-angle lenses, but there are a few odd internal reflections and flare when shooting into the sun which you can either live with and use creatively or just try to avoid by being very careful with your compositions.

Vivitar 17mm f3.5 Canon 5d Mk2

As with all wide-angle lenses converging lines look particularly dramatic – you end up looking for them everywhere. The closer you are to the subject the more dramatic the effect is.

Vivitar 17mm f3.5 Canon 5d Mk2

As there’s so much depth of field you can also use the depth of field scale to ‘shoot blind’ and just hold the camera near the ground like the following shot. After lots of experimenting it seems the depth of field scale is a bit optimistic – use the next widest aperture scale (i.e. set f16 but set a hyperfocal distance for f11). Maybe it was ‘good enough’ for film but it’s not for critically sharp results on the 5D…..

Vivitar 17mm f3.5 Canon 5d Mk2

Using such a wideangle lens for close-ups isn’t advisable due to distortion which increases the closer you get. The closest focus distance is 25cm – use it if you dare!

And another using the same technique – one of the few shots of snowdrops I’ve taken which I like – and I’ve taken loads!

Vivitar 17mm f3.5 Canon 5d Mk2

Bokeh with such a wide-angle lens only appears when the lens is closely focussed. It’s slightly fussy but not bad.

After all these promising results, time for some proper test results. This scene was chosen to be especially demanding for a wide-angle with bare branches acting to test the sharpness.

At f3.5 centre :-

Vivitar 17mm f3.5 Canon 5d Mk2

Well wide open it’s not that good at all – the edge is terrible, but having read detailed test results for such lenses – even modern ones – the extreme edges of wide angles are often poor. Conclusion – avoid f3.5!

at f8 centre :- Vivitar 17mm f3.5 Canon 5d Mk2f8 edge :-

Improved as you’d expect, though still not exactly brilliant!

at f16 centre :-

Vivitar 17mm f3.5 Canon 5d Mk2

f16 edge :-

Vivitar 17mm f3.5 Canon 5d Mk2

Much better – relatively… The extreme edges of the frame are still not great but better than I expected.

All things considered, this is remarkably good for a £100, thirty year old lens. As long as you keep it at f8 to f16 the performance isn’t too bad at all and on a par with many modern ultrawides (especially mid-priced zooms). It’s so much fun to use that I don’t really care too much about the soft edges – with such a wide angle of view they don’t seem too important. If you’re a perfectionist or pixel-peeper though this may not be good enough for you.

For someone who needs such a wide-angle lens infrequently this is good enough for me (and becoming a favourite lens). The lack of chromatic aberration is remarkable, the flare which crops up now and again is quite attractive (to me anyway) so all in all it’s getting a hearty recommendation for the price.

I’ll finish with another shot from the waterfall sequence – the slight vignette is caused by stacked ND filters, not the lens.

Zuiko 50mm F1.4 on a 5D Mk2

A post from last year tested this lens on a Canon 60D, and found it to be an excellent manual focus alternative to a modern AF lens. As my Canon 50mm f1.4 is going for repair after a bash resulting in misaligned lens elements, the older 50mm has been resurrected. To illustrate the difference in construction quality, the all metal constructed Zuiko is 34 years old and has been knocked around over the years. The modern plastic made Canon lens has lasted 6 months of light use and failed at the first collision …..

Canon 5dMk2 Zuiko 50mm f1.4

Doing what it does best at 1.4. Shallow depth of field, heavy vignetting, and an ‘expensive’ look.

Anyway, gripe over, is it as good on a full frame sensor as on a crop sensor? On the 60D it’s a 80mm-ish equivalent lens, on the 5dMk2 it’s a proper 50mm.  You would use this as a general purpose standard lens on the 5DMK2 to create shallow depth of field effects, half length portraits and in low light – 1.4 is very fast. The filter thread is an economical 49mm, hence the B+W filter – unusual as I’m usually too cheap to pay for expensive filters. The EF to OM adaptor is the same old Fotodiox used for earlier posts.

Canon 5dMk2 Zuiko 50mm f1.4

Mounted on the 5DMK2 body – maybe a little on the small side for this body but it works well.

It looks a little small on the bulky 5dMk2, but not ridiculously so. It’s quite heavy and doesn’t protrude too much so is nicely balanced. Focussing is easy at f1.4 on the standard focussing screen.

Canon 5dMk2 Zuiko 50mm f1.4

Close focus at f1.4 is tricky as any slight movement after focussing moves the shallow depth of focus area – literally millimetres deep! Focus bracket if it’s a good shot. This figure is around 12 inches high.

Right then, onto the test area – the mill. It’s effectively a brick wall, but a very scenic one. If you don’t like looking at test results, look away now (well scroll down to the conclusion anyway). All shots processed in DXP Optics Pro 9, downsized and resized in Photoshop.

At 1.4 images are a little soft with low contrast as you might expect, but by f2.8 things are sharp, the contrast has improved and the vignetting has disappeared. An excellent result all round and very useable, with performance peaking at f5.6 to f8.

Just out of curiosity I also shot this test frame using a 24-104mm L series lens at f8 at 50mm for comparison purposes.

Canon 5dMk2 24-105mm L f4

Canon 5dMk2 24-105mm L f4

The L series has an advantage as DXO knows what lens is attached so can do lens specific corrections, distortion correction and bespoke sharpening – something it can’t do for the Zuiko. The Zuiko can’t match the modern zoom for biting sharpness in the centre, but it is three stops faster and looking at these full size on a monitor (rather than pixel peeping) I’m not sure I’d notice the difference.

Canon 5d Mk2 Zuiko 50mm f1.4

The slightly greenish hue to out of focus areas is a feature of the old Zuiko (and many fast lenses).

In conclusion, it’s just as good on the 5dMk2 as it was on the 60D, with shallower depth of field (see equivalence), a super fast f1.4 max aperture and an ability to produce images with real ‘depth’. Get hold of one if you can. I’m rather glad I didn’t sell it six months ago!

Variations on a Theme

Or maybe this should be called “messing around with an old key” because that’s what it is…. This old church key must be around one hundred years old, and opens a very heavy wooden door. These were all taken on a fairly quiet drizzly day, wandering around trying to get some inspiration.

All shot on a Canon 60D with a Fotodiox EF to OM adaptor and the ever amazing Zuiko 50mm f1.4 at maximum aperture. All taken at around 40 cm – closest focus – the tiny depth of field and lovely bokeh complement the subject nicely. The background is the sill of a church window, with soft light filtering down from above. The toning is done in DXO filmpack.


Same subject – lower angle. I tried several shots moving the focus point back and forth, but this one seemed the best.


Finally one casting a slight shadow.


Just goes to show inspiration can crop up from anywhere!

All images shot for the book cover market – hope you like them.

Manual Focus Lenses on A DSLR – The Search for that ‘Magic’ MF Lens

When this series started I was really excited about doing some proper tests on lenses which I’d used on an Olympus 620 and a Canon 60D for several years. Always in search of that ‘magic’ lens which would give images a special touch, this post is a summary of my experience working with these lenses.


This is a shot from the Vivitar Series One 70-210 – quite close to that ‘magic’ lens

There are a few complete duffers which I didn’t bother to test – but they didn’t cost much so it didn’t matter – and here’s one.


The unbelievably small Industar 50mm f3.5. It’s so small it’s unusable really, and the results – from this copy – are not that good, so the planned test was cancelled.

To make their use worthwhile, MF lenses must offer either a significant aperture speed advantage over a kit lens, or show some special optical quality which modern AF zooms can’t create at a bargain price which makes them attractive.

Of the lenses tested, running from 17mm through to 300mm, it’s the ones in the 24mm-85mm range which stand out.


Is that a lenscap? Oh no, it’s an Olympus EPL3! Another one where the test was abandoned – a ‘loaner’ from Pete and Jayne, a 400mm Tokina f5.6. Is MF with an 800mm equivalent possible? Maybe, but it’s just not worth the trouble. Testing the 300mm was bad enough – I’m not doing extreme telephotos again!

Less than 24mm and the max apertures are about the same as a kit zoom, and the performance more or less the same.

At 24mm to 85mm the aperture advantages are significant, as are the corresponding improvements in bokeh.

After 85mm, things start to even out again, the difficulties in focussing MF lenses at smaller telephoto apertures – just when you need critical focussing – start a downward turn which at some point becomes a breaking point. For me it is 135mm at f2.8. After that telephoto lenses become progressively more difficult to use as the max apertures get smaller – autofocus and image stabilisation start to become indispensable.

The ‘stars’ from the tests then –

The Zuiko 24mm f2.8 is a brilliant 35mm equivalent on a 60D. Sharp, contrasty and light.


Unreservedly recommended – the Zuiko 24mm f2.8. I must get one!

The Zuiko 50mm f1.4 is very good even wide open and a good portrait lens.


The Zuiko 50mm f1.4 – lovely colours, shallow depth of field and a perfect portrait lens.

For sheer eccentricity the Jupiter/Helios 85mm f2 is the best of them all, producing some unique results – the closest I’ve come to that ‘magic’ lens.


The Helios 85mm f2 – the soft bokeh and image softness are a unique combination. The closest to my mythical ‘magic’ lens so far.

The Zuiko 85mm f2 is the ‘sensible’ alternative to the Helios. Both produce results at f2 which are very different to a kit lens at 85mm at f5.6.


The Zuiko 85mm f2 – not as crazy as the Helios but more predictable. Some might prefer it’s cooler more restrained images.

For macro, the Zuiko 50mm f3.5 is also a good general purpose lens, but I’d rather have the zoom range and macro capability of the Vivitar 70-210 f3.5 Macro. However, I’d need to know it was needed before all that weight went into the camera bag.


The Vivitar 70-210 f3.5 Macro – a legend of a lens and excellent on digital. The macro mode is superb. I just wish it weighed a bit less!

If I’m being brutally honest, the list stops there. When you come to pack the camera bag for a shoot, the Canon EF 70-300 is always going to be preferred to any of the MF lenses past 135mm, and probably 85mm. There just isn’t the compelling case to regularly use these lenses at their max aperture/weight/size/performance – it’s as simple as that.

Any of the four lenses above are a very good complement to a wide/standard and a telephoto AF zoom. With the exception of the Vivitar they could routinely be carried in the camera bag without weighing you down too much. None of them should cost more than around £140.

So – this test series finally finished ! It’s been good fun and worth the effort – even if it’s only to pare down my collection of old lenses to the best ones. The only downside is that now I’m on the hunt for a Zuiko 24mm f2.8….

Manual Focus Lenses on a Canon 60D – A Zuiko 300mm f4.5

This is the thirteenth of a series of posts for photographers who want to try cheap(ish) but fast manual focus lenses on an APS-C DSLR. The series ends with the monster Zuiko 300mm f4.5, on loan from Pete and Jayne who might be happy that so much bulk has been temporarily removed from their house. I’ve lugged this thing around for a week or two, trying to get six decent shots to test its qualities but it’s a tough challenge, mounted on a tripod or hand-held.


Horton Tower from the North – it’s on the horizon a mile away from where this was taken. Quite good contrast and sharpness.

With an effective cropped focal length of 480mm it’s well into specialist lens territory, and the tiny angle of view and huge magnification make it’s use difficult at best.  Supporting the bulk of the lens with the left arm when shooting hand-held made the muscles ache after a few minutes – photography and weight lifting at the same time – a novel experience!


The bokeh is a bit ‘busy’ but not too bad at all.

Just aligning the lens with a small distant subject is in itself a bit of a knack. The best way is to line up the top of the lens looking down the outside of the barrel, them move the eye to the viewfinder. I imagine it’s the way old cannons (not Canons) were aimed.


Telephoto perspective compression is extreme – as is the shallowness of depth of field at all distances.

Apertures run from f4.5 to f32, the minimum focus distance is 3.5 metres and the filter size is a standard 72mm screw in type.


After a plenty of practice, the trick is to find something fine and contrasty to focus on, in this case the telephone wires. If you need to make sure do some focus bracketing!

The attached tripod mount addresses a definite requirement for camera stability, and suggests that the Olympus designers thought the weight might put unacceptable strain on all metal OM bodies. Even on a day with light winds, using ‘focus magnify’ on the 60D’s LCD, the image jittered around –  and it’s a fairly heavy tripod.


The attached tripod mount at the base of the lens. The knob is to loosen it so it can be rotated for portrait/landscape – or any other – orientation.

The lens itself is probably the best made lens I’ve seen – solid, precise all metal with a wide focus ring – generally gorgeous. It’s far removed from the tiny ‘jewel like’ Zuikos everyone’s familiar with.


Even the bulky 60D is made to look insignificant – this lens is a giant. With the built-in lens hood extended it only gets worse. The Fotodiox adaptor used wasn’t relied upon to support the lens unaided, but I’m sure it would have coped.

Just a few test shots this time. It’s difficult to find a suitable subject at this focal length – you need to be a long way from it. This tower seemed like the best bet.


This is Horton Tower from the South and a but further away. The frame to the right is darker due to a very out of focus tree – nothing to do with a lens fault.

But lurking in most shots with backlit subjects is a bit of a horror – really bad chromatic aberration. It’s most obvious at f4.5 but it never really leaves images taken at any aperture. It also appears around the out of focus areas as red/green edges to the highlights.

Sometimes it’s purple.

f4.5 centre

This is the top left of the tower. Not good.

And sometimes it’s red. I had the Zuiko 180mm f2.8 years ago and it suffered from the same problem. Maybe it’s inevitable at these focal lengths and fast apertures.


This is an enlargement from the centre of the frame.

So,  is this lens worth the £300 they go for second-hand?

Unfortunately – no.

Unless you’re the sort of photographer who doesn’t mind its drawbacks of chromatic aberration, very difficult manual focussing and epic weight and bulk. At f4.5 it’s only just faster than the f5.6 at 300mm of an AF zoom, which is a fraction of the weight and performs just as well – better in fact for CA.

It’s a beautifully made thing though, and I can see why collectors buy them. For practical photographic purposes though it’s pretty bad. In this case at least, a very high quality lens with an extreme focal length which was good enough for film just doesn’t cut it for digital. It really makes me admire the skill of 35mm photographers using MF lenses like this to capture fast-moving sports images.

Still, it’s been great fun – if slightly frustrating – to have a play around with. If I’m honest though I’m glad this test is over!

Manual Focus Lenses on a Canon 60D – A Zuiko 200mm f4

This is the twelfth (and almost the last!) of a series of posts for photographers who want to try cheap but fast manual focus lenses on an APS-C DSLR. The subject of this mini review is the Zuiko 200mm f4, a 320mm equivalent on an APS-C DSLR and just a bit faster than a 75-300mm AF Canon zoom lens at the same focal length. This ones another on loan from Pete and Jayne – Pete apparently has a weakness for telephoto lenses.


The lens is easy to focus in bright light, and produces some excellent results using centre weighted metering mode.

The filter size is 55mm and the aperture range is f4 to f32 (not sure why f32 is needed but it’s nice to have). The focus rack goes from infinity to the minimum focus distance of 2.5 m in quite a bit more than 180 degrees.


Colours are on the cold side, but very acceptable. The contrast across the aperture range is good too, better than the 135 f2.8. The depth of field is obviously very narrow at 200mm at f4, and the bokeh is pretty good.

The built-in lens hood protects the front element from flare effectively, and makes me wonder why they aren’t built into all lenses.


In bright light there’s not much chromatic aberration (purple on the left top of the sign), and telephoto compression is starting to get very pronounced.


More very soft bokeh and sharpness of in focus areas – this is excellent.

Physically the lens is made to an exceptionally high standard – light weight and all metal with a real quality feel to it. It ‘fits’ the 60D really well, the generous focus ring is smooth – all pretty much perfect.


The lens mount adaptor is the very well made made Fotodiox EF to OM.

A great MF lens then, and highly recommended? Like the 135mm f2.8, a qualified yes. F4 is only 2/3 of a stop faster than a normal tele zoom lens so there’s no real aperture speed advantage. Focussing in dull light is at best ‘hit and miss’ on the standard 60D focussing screen even for stationary subjects – let alone moving ones. As sports and nature photography are this lenses’ home territory this is unfortunate.

The negatives aren’t about the lens itself, which is truly excellent, rather about using medium telephoto MF lenses on DSLR. I’m a bit sceptical about the need for AF up to around 85mm where the speed of equivalent MF lenses make focussing easy. As the max apertures drop to f2.8 at 135mm, and f4 at 200mm, the focussing screens get darker, and the focussing becomes progressively more critical – two unavoidable principles of optical design. As a consequence, AF comes into its own at longer focal lengths, as well as IS.

For me the ‘break point’ is 135mm. I took loads of shots for this test, but those taken on overcast days weren’t that good – though that might be just me!

In conclusion then, if you’re determined to use one or have one lying around give it a try but be aware that focussing on anything other than a sunny day may be a problem. If you’re not that determined, I’d suggest instead a modern AF lens – the Canon EF 70-300mm is a good all-rounder, even if the build quality doesn’t come close to these superbly built old Zuikos. A final alternative, even if it is a very heavy one, is the Vivitar 70-210 f3.5 macro, which is a bit easier to focus, and has a very nice macro mode too.

These lenses are relatively rare on the second-hand market varying between £90 and £150 (there’s a cheaper f5 version too).
