This 90 is a real winner of a lens for me. I've only used a few M-mount lenses, and I haven't enjoyed the handling heavier ones much at all (CV 40 f/1.2 and 50 f/1.5). I assumed all the 90's were going to be too long and heavy, but evidently not. Saw this locally for a nice price and decided to grab it, and the handling is just perfect. Light, slim, and no frame blockage. It's also a nice fit on the Z's as well.
