This is another Nikon AF glass I extensively used in the past and sold when moved to Fuji X. I tried XF 50-140mm f2.8, but lens didn't fit my personal expectation. Yes, there is quick autofocus, IS, and super sharp image (even bit sharper than I want). That lens it's large, heavy, expensive, and bothers me by extra digital operations and noise. Also 140mm was a bit limiting after using of XF 55-200mm. Today I received great Nikon AF 180mm f2.8 ED sample from Japan in near mint conditions for only 2/3 of the price I sold my previous one. This lens is built like a tank, has quite convenient focus ring position, and of course f2.8. One of the downside - no tripod collar. But it's not too heavy and works great wide open, so shooting experience on Fuji X-E2s is very pleasant. Welcome back, Nikon : )
