I write this on the first morning of 2020. Didn't have time to do wrap up yesterday with skiing, packing, driving and party in the evening, but now feels like a good time, as others are still sleeping. Happy new year everyone
I chose M85/2 for December on purpose as I had plenty of travel in program and wanted to have a lens I knew to provide excellent results and it didn't let me down. Plenty of keepers from this month and of course only handfull visible here on the challenge. So photograficly a good month. My performance on SIC, on the other hand, not a perfect ten. I did the main functions of shooting daily and posting pretty much on time, so that's allright. But I didn't have time and energy to go thru the shots from the others. So I apologies my antisocial behaviour and thank everyone who had the motivation to go thru my shots and leave comments. I'll try to do better on January.
M85/2 is the cheapest 85mm in Pentax catalogue and, I believe, also the smallest. I guess this is very much you get what you pay for -situation. I do like my M85, but based on the shots I've seen lenses like A*85/1.4 are even better. But as I don't do paid work, the M85 is budget friendly and perfectly good enough portrait lens that is also easy to carry along on travel. As typical with M's this lens gets softer wide open. I remember avoiding it on APSC, but with FF it looks sharp enough on monitor size and I took plenty of shots wide open this month. There's an old sharpness test available on internet which give this lens really bad results wide open, but I don't believe my copy falls that much in sharpness, so there might be sample variation or K1ii is a real miracle maker
This lens can produce annoying purple fringing and lots of green fringing, which to me is less disturbing. I had to manually desaturate purple out of some shots as the automatic clean up didn't manage to fix it. Stopped down to f5.6 fringing is pretty much gone, so wide open in strong contrast might not succeed with this lens and it's something you need to be aware of.
Otherwise I have no complain. Bokeh is nice, Transition good and sharpness easily good enough for me. Definitely a keeper and will stay on my travel bag also in future. I continue SIC in January with M150/3.5.
