This unlikely post is about the unholy match of two pieces of photographic kit from opposite ends of the image quality spectrum – the superb 36MP Sony A7R and the odd (some might say weird) Plastic Lensbaby lens which is designed to produce soft ethereal images. Why? Well it’s an experiment which sounded like fun, and trying to coax any decent results out of the Lensbaby is always an enjoyable challenge.
I’ve tested this lens on an Oly EPL5 , a Canon 60D and a 5d Mk2 and came to the conclusion that the Oly produced the best results as it uses just the centre of the image circle. I have a feeling after this test the conclusion might be the same – but here goes.
Even for someone using light Zuikos this 50mm lens is light – 125g or 4 1/2 oz. Mounted on an inexpensive Fotga adaptor for Canon EF to NEX mount, the focus ring is alarmingly sloppy, the apertures are waterstone stops held in by magnets at the front, and the relatively sharp centre of the frame can be moved around the frame by undoing a friction clutch and moving the lens about like some sort of mad sci-fi monster’s eye.
As the images will be soft you can forget about shutter shock, chromatic aberration (it’s terrible!), changing aperture (it’s a pain so I tend not to) and camera shake. Put the camera on auto-ISO, focus and shoot – all very liberating and not your normal photographic experience. Crucially, the focus peaking works very well on the A7R, ably illustrating focus curvature (to explain :- imagine focussing on a brick wall parallel to the sensor – the centre will be in focus, the edge won’t be, but de-focus the centre and the edges come into focus). In reality it’s so far from normal photography it’s fantastic!
Rather than a resolution test (don’t be silly!) here are a few shots shot at different apertures so you can judge the effect of different aperture disks, F2 to f22.
Personally my favourite is f8 – just about the right amount of ‘Lensbaby-ness’.
All Lensbaby images need lots of post processing – the following have been pushed through (a slightly baffled!) DXO Optics 9 and then DXO Filmpack.
First some mono conversions :-
And some with colour film conversions using different DXO Filmpack profiles :-
This is a real ‘marmite’ (UK expression – you’ll either ‘love or loath it’) lens. With some serious PP it does open some interesting possibilities if you don’t mind the odd look from passers-by while you change the aperture disks. Mono works well, but the colour ones work better for me, and the stronger the colours the better – don’t be half-hearted in the conversion!
It’s use on an A7R is genuinely better than on DSLR’s with optical viewfinders because you can make sure things are in focus – well, as much as they’re ever going to be in focus! The Sony’s exposure metering was also very good – something my DSLR’s struggled with using this lens. The Oly EPL5 produced images which looked more ‘misty’ than these – not a better result but just different as each could have their use.
Maybe it’s best thought of in the same way as the Olympus ‘dramatic tone’ filter – good in small doses to produce something different but make sure you don’t use it all the time. I’d recommend using one just for the sheer challenge and fun of using them – you though may (sensibly) prefer not to!
Commercially the images can sell (two or three have over the years) but they’re a bit ‘niche’ even for the book cover market.
Thanks for looking, hope you find this useful.
