rconey Posted February 7, 2019 Share Posted February 7, 2019 Just now with a quick comparison of my135 f2.8 QC (1.3 pound) to the Zeiss 100 f2 (1.5 pound) at f5.6 the sharpness is about the same, center and corners but the zeiss has better control of chromatic aberration in front of and behind the plane of focus. Just think what I will carry backpacking, and the weight of it all..... That 135 f2.8 QC is a nice lens. Link to comment Share on other sites More sharing options...
Brian1664876441 Posted February 8, 2019 Share Posted February 8, 2019 Just a note on "Zoom Creep": I fixed it on my late version 80~200/4.5 by taping out the front element and working a little vacuum pump grease into it. Link to comment Share on other sites More sharing options...
