二手 Nikon Nikkor-Q 80mm f4 水下定焦鏡頭

The focus ring on this used 80mm f4 is surprisingly smooth for a lens this old. I took it on a dive trip last week and the underwater housing mount worked perfectly, gave me crisp shots of a sea turtle.

The glass is crystal clear even after years of use, and the f4 aperture gives sharp results on reef shots. Focus ring turns smoothly underwater, and the build feels solid enough for saltwater abuse. Definitely worth the price for a used prime that still performs.

Took this on a few dives and the manual focus ring is buttery smooth even with gloves on. Sharpness through the viewfinder is exactly what I hoped for from a prime lens in the water.
