There's been a lot of talk about the Oly 17/1.8 recently - is it sharp enough, etc. Is this a world class sharpness lens edge-to-edge for landscapes? No it isn't. I have used several lenses which have better edge sharpness, some which are MFT lenses and others which aren't. Still, this is absolutely one of my favorite lenses because it ticks so many boxes which matter to me. Great close up performance (unlike X100S lens, for example). Great autofocus speed (unlike most non-MFT options). Great build. Compact size. Pleasing character. Relatively low color fringing. And plenty of sharpness for my usual purposes, which mainly involve taking photos of people. Here are several large samples from a family outing to an elementary school event. Please add your own high-res (minimum 2000px) samples from this lens to this thread so we can get a sense of what it can do.
