Fujifilm makes some fabulous medium format lenses for its GFX cameras but prioritizes primes. At the time of writing this review, primes outnumber zooms in the line-up by 12 to 5. The GF 100-200mm is the longest telephoto zoom in the range but, due to the kind of inverted crop factor of medium format image sensors, it still only has an ‘effective’ zoom range of 79-158mm in full-frame terms. For serious telephoto reach, that doesn’t compare too favorably with ‘trinity’ 70-200mm f/2.8 telephoto zooms for full-frame cameras.
