Got a new "old" toy for the D750. It's a Nikon 75-150 f/3.5 (early 80's). Somewhat of a legendary older manual lens. I've been lurking around uses lens sights waiting for a copy in pristine condition and this one is like it came right out of the box. The quality of these older lens really is top notch. I'm really enjoying the huge and smooth focus ring (it's a push pull zoom). I got it mainly to try for video. I can manually focus it and zoom in and out with one hand simultaneously. It takes great stills too. Surprisingly sharp. One thing I think I've noticed about older lens is the new lens outperform them in low light at the same aperture. Maybe that's barrel diameter or coatings or some other tech that is in new lens. Anyway. Just decided to share. BTW, it was less than $200.
