Bryan Posted November 3, 2014 Share Posted November 3, 2014 I find that, with a 1.5x crop factor on the Sony NEX 6, a 28mm's 42mm equivalent is a very useful focal length. I f you can find an adapter with accurate registry, it becomes very simple to use. Dial in a distance and shoot, the depth of field is enormous, so it's difficult to get it wrong. It's a bit like shooting with a sophisticated box camera. I've not tried any exotic glass, but have experimented with run of the mill 28s by Pentax, Olympus and Canon. From my limited testing there's not too much to choose between them, but I prefer the smaller package and simpler fittings associated with the Pentax and Olympus lenses to the more complex bayonet connection of the Canon FD. My pick of that particular bunch is the 28mm f3.5 Pentax K, one of the earliest Pentax bayonet lenses. I find that it produces less distortion and CA than the more recent M series, while providing a similar level of sharpness. Three downsides, it's a bit bigger than the M lenses, it takes a weird (for Pentax) filter size, and they tend to be quite a bit more expensive. Not tried Minolta nor Nikon, while Leica is definitely beyond my budget. I guess that Zeiss probably has a good but pricey 28, but not looked. Anyone else interested?
