>>2959998Some are, others are not. I'm too cheap to buy native lenses for my MFT snapshitter, so I use my film glass with adapters instead. The results vary greatly. For instance, I thought the 3.5/28 Takumar would make a great standard lens, but far from it. Its edge performance is utterly awful, I haven't seen edge blurring as bad with anything else I've ever used. On a film body it's great, but adapted to MFT the results are garbage. Meanwhile the 3.5/135 Takumar (pic related) turned out great for a cheap-ass tele option on MFT, while the 2.8/135 Cosinon delivers puke-inducing chromabs.
Minolta MD glass works great aside from the 2.8/35 which is shit in general, the 2/45 pancake Rokkor is sharp as always and the 2.8/28 makes a good standard lens stand-in. I was also surprised to find that the 5.6/300 MC was actually quite sharp, although nigh impossible to use without a tripod. Likewise Helios 44 and Industar 50-2 are good, got some nice portraits with them.
>>2960052I've found that when adapted to MFT, most fast standard lenses glow. I'm not sure why that is, the glow goes away when you stop down. Handy for portraits I guess, personally I find it just annoying.
