I haven't use this lens much lately (OM 24mm f/2.8), except on film. Still, I'm finding old images from it that I hadn't shared. It's a superb lens, if you find yourselves with a good multi-coated copy.
Santa, via FedEx and KEH, just delivered me a Mint++ OM 90mm f/2 Macro. Couldn't be closer to brand new and it appears the functionality matches the appearance. After I climb the learning curve I hope to be able to post some results.
One more for the season. For several years I used a Canon 1Ds2 with the 180mm f/3.5 Macro lens. This OM 90 f/2 on an a7r2 is one fifth the size and weight, and three times easier to use with better IQ and a much higher keeper rate. To say I am delighted is an understatement
