Just traded in a Canon G9, a Oly EPL3 and a spare OM2n body to raise funds for a new Sony RX100 – and it’s very good so far. So if anyone’s wondering if you can shoot infrared with one the answer is yes!
The R72 filter is just held over the front over the lens, and after a bit of experimentation a +1 exposure compensation and ISO of 400 to 800 ASA allows hand-held exposures at 28mm at f1.8 on a sunny day. Focus is a bit hit and miss. Shooting RAW allows for the inevitable post processing.
There’s a slight hot spot’ of brightness in the centre but it’s easily edited out. Processing consisting of de-saturating the red and magenta channels (there’s no other colour information).
In addition to the IR R72 filter, carrying a three stop neutral density filter in a shirt pocket allows the use of the widest apertures in bright conditions for ‘normal’ photography – the minimum shutter speed is 1/2000 th of a second.
Up close the IR results are grainier than a ‘normal’ shot, but at 20MP it’s nowhere near as noticeable as using a 12MP sensor.
With a bit of practice this should be a tiny, versatile camera in conjunction with the two filters.
Hope you find this useful – thanks for looking!
