I was looking for something on eBay and came across a listing for a 35mm f1.6 C-mount CCTV camera lens at £17.42 that said it would cover the whole frame on APS-C. I also noticed that you can get a C-mount lens adapter for my Sony Nex, which is an APS-C sensor, for £3.75 Does anyone think that this will actually work, or am I likely to find that it's dark at the corners or something? I'm a bit tempted, but it's more than I really want to spend for an experiment, and I don't actually need it much. The lens is listed here: http://www.ebay.co.uk/itm/371926369217 The adapter is here:http://www.ebay.co.uk/itm/221952661970
A guy at work showed me his CCTV lens on a Canon M3. Bokeh looked nice, but there is a lot of vignetting on all of the corners.
I had a feeling that would be the case. OK, not a good idea then. Maybe if I ever get a micro 4/3rds camera...
