I tried the 23mm F2 and sold it quickly : it has NONE of the rendering of the 35 F1.4. or even the despised 18mm F2. It's flat. Boring. Dead.
Fortunately, the 50mm is none of that. It's marvelous, and for 200 grams I have a short tele I can take when hiking for landscape closeups, big animals, hiking friends portraits etc. Bokeh is very good on that one. Rendering is "3D" unlike the 23 F2.
18mm because other wide options are too big/heavy for me to take everywhere and it has, despite extreme corners softness/distortion/fringing, a fantastic rendering. Just don't fight against it and put an important (human...) subject in an extreme corner when you frame and you'll be absolutely fine, no one will be able to tell not even you. It's really a fantastic lens that I had to buy again after selling it stupidly.
The 35mm f1.4 is still the best fuji lens and nope, the 35mm F2 does not match it. It might be "90%" of it as some reviews claim, but those 10% account for an incredible, very pleasing, film-like picture vs a "good digital one" IMO. I'm still thinking I will add it to my kit because it's better if I'm hiking in snow and make F8 landscape pictures vs not taking the 1.4 at all
Eagerly waiting for a 16 or 18mm WR F2 lens so I can have 18-35-50 WR with the 35 F2 being so-so but able to take all abuse I throw at it, and keep the 35 1.4 warm and dry for important stuff.
