On paper, autofocus looks good, with a very large number of autofocus points, with the size of the focus point area selectable from spot to large—very nice. And in many if not most situations, the AF locks on brilliantly and exactly right. But not always, which means that I have to zoom in to check for critical focus.
The 63mm f/2.8 is a stepping motor lens* with crude in/out focusing driven by a noisy lens motor. I find this disconcerting at best after working with Nikon and Canon and Sigma’s ~silent modern autofocus. It’s just not the same quality experience. The 120/4 is better with its linear focusing motor, but the steady electronic hum while in use and clunking when not in use is not my cup of tea either. The focusing experience feels crude in comparison to 35mm DSLRs, to Sony mirrorless, to the Hasselblad X1D—well, it feels like medium format has been all along! Maybe other Fujifilm GF lenses will be better, but the 63/2.8 sets a disappointing precedent for a key lens in the lineup: I was expecting silent internal autofocus**. As far as I’m concerned, Zeiss native-mount primes for the GFX would be highly appropriate and welcome. Or for that matter, Sigma’s Art lens superior fit and finish and focusing.
