Olympus 50mm lenses
Thre
are two common Olympus OM 50mm lenses, the 50mm f/1.4 which typically
sells around $100 and the Olympus 50mm f/1.8 which goes for $20-50. I
initially bought the 50mm f/1.4 but some reports say the OM 50mm f/1.8
is better at comparable apertures, so on a lark I bought the 50mm f/1.8
too. As I did not find any side by side comparisons, I thought I'd
throw these up. Of course these are older, used lenses, and just one of
each, so sample variation may play a huge role in the performance.
Typical business; shot raw images on a Sony A7, mounted on a tripod, same shutter speed for each aperture, white balance matched, focused to infinity in 10x live view at widest aperture and finally, converted via ACR with default settings for sharpening, the only non-standard setting if the camera profile being neutral.

I'd guess that the fence is not perfectly parallel, so corner crops are just an indication of what the lenses can deliver.
Center and just off center 100% crops.

At f/2.8 we truely share an aperture value.
