The first impression of the Fujinon GF 30/3.5 lens is clearly positive. I noticed that when you use it wide open at ƒ3.5 the border sharpness is lacking a bit. (Center sharpness however, is always excellent). Once you stop the lens down, it is razor sharp from corner to corner - very nice !!

Minimum focus: 32 cm

Another thing i noticed is that the relative close minimum focus distance. However, the bokeh in the background appears nervous when you go close. I usually counteract this with a touch of artificial lens blur (Photoshop Camera RAW) in order to smoothen the nervousness a little bit (because I find the original bokeh being on the ugly / distracting side).

I have no yet observed any AF inconsistency. (Which is nice, of course). Therefore I lean more and more towards the belief that main problem are adapted lenses (in my case via the Fringer Pro adapter) which seem to be more prone to AF inconsistency. Lesser adapters are even worse in that regard.

The Fujinon lenses do it pretty safe. They may not focus very fast on a contrast-based AF sensor in Fujifilm GFX 50 models, but surely the AF focus works (most often) pretty accurately. It can of course get fooled when you focus on certain structures / patterns (resulting into back focus)

I believe that the 30mm lens is perfect for a wide angle lens on a Fujifilm GFX camera. Because of the native format, the equivalent 24mm do not feel as wide, like on a fullframe camera. Therefore, I deem the Fujinon GF 30/3.5 being a great companion for landscapes, cityscapes and other images where a certain "wideness" is required, with looking too wide.

XPan views

When you enabled the camera's XPan format with this lens, you get basically the same equivalent view, like the 45mm f 4 lens gave on the (analog) Hasselblad XPan camera. But with the Fujifilm GFX combo, you can get closer - which wasn't possible with the original XPan camera.

Very cool indeed.
