二手 Pentax-A 80-160mm F4.5 645 MF

The zoom ring has a nice, smooth resistance that makes precise framing feel deliberate and satisfying. Paired with the 645's viewfinder, manual focus is quick to hit critical sharpness, even for a used lens.

I've been using this 80-160mm f/4.5 for landscape shots, and the manual focus ring has a smooth, precise feel that makes fine adjustments easy. The used condition was better than expected—just a few tiny marks on the barrel. It's become my go-to for medium format portraits.

I was nervous buying used glass, but this 80-160mm f/4.5 feels solid and the manual focus is smooth as butter for my 645 body. The short-telephoto range is exactly what I needed for portraits, and the aperture ring clicks with satisfying precision.
