Digital Camera World Verdict

Medium format zoom lenses are a rarity, so the Fujifilm GF 45-100mm f/4 is welcome for that fact alone. However, this near-standard zoom (with an equivalent 36-79mm focal range) is also an impressive optical performer, though its sharpness dips slightly at the tele end – and there is an apparent anomaly at f/8 (at least with our review sample). An excellent all-purpose optic, it would be a valuable addition to any GFX owner's kit bag.

The Fujifilm GF 45-100mm f/4 R LM OIS WR is the manufacturer's first attempt at a medium format zoom lens – two things that don't often go together. When they do, however, the stars can align for a very special optic indeed.

With its 35mm equivalent focal range of 36-79mm, this is as close to a standard zoom as you're going to get on a GFX camera, making this a valuable all-purpose lens on paper. And, when paired with the best medium format cameras made by Fujifilm, this has the scope to turn something like the Fujifilm GFX 50R into the ultimate walkabout powerhouse.
