Fuji Fuji 135mm f2.8

Overview

No genuine 'Fuji 135mm f/2.8' prime lens is described in the provided reviews. In fact, one source (Fuji X Weekly) explicitly notes that Fujifilm's X-mount lineup has no native prime longer than the 90mm f/2 (aside from the large 200mm f/2), and suggests Fujifilm 'should consider adding a prime lens that's longer than 90mm, such as a 135mm f/2.8.' The reviews instead cover third-party 135mm f/2.8 lenses adapted to Fuji X (a Vivitar 135mm f/2.8 built by Komine in 1978, and an East German Pentacon 135mm f/2.8) plus the Fujinon XF 18-135mm f/3.5-5.6 zoom. Because the requested lens does not correspond to any lens actually reviewed here, no accurate development history can be provided. unknown

Verdict: The provided reviews do not describe a native Fuji/Fujinon 135mm f/2.8 prime lens for Fujifilm X mount. One source explicitly states no such native prime exists in the X lineup. If you are looking at a '135mm f/2.8' for Fuji X, it is almost certainly a vintage third-party M42 lens (e.g., Vivitar/Komine or Pentacon) used via an adapter, which is a different product than what was requested.
