I really like how Leica has several different lens line-ups; the main ones being Elmarit (f2.8), Summicron (f2.0) and Summilux (f1.4). Fujifilm seems to be heading in the same direction with the present f2.0 line-up, which I happily call the "Fujicron" line!
Unfortunately Fujifilm wasn't able to maintain the 43mm filter size of its two older brothers and has increased it to 46mm. It weighs in at 200g, only slightly more than the 170g and 180g of respectively the 35 and 23. Overall the lens still feels light and nimble and a joy to work with.
The lens is available in silver and black; for stealth shooting, I definitively prefer the black lens, even on a silver X-series camera, but that is a personal choice.
Like all XF- lenses (except 27mm pancake lens), Fujifilm always provides a lens hood with the lens; especially companies like Canon please take note! Because of the longer focal length, the 50mm plastic lens hood is a bit larger than the 23mm and 35mm f2 provided ones. When mounted inverted on the lens for packing, it doesn't protrude. A third party metal lens hood is available if one so prefers.
Even if shooting directly into the sun I noticed virtually no sun flare; a tribute to the new Super Electron Beam Coating (EBC).
The first two f2 lenses, are known for their very fast and virtually quiet auto-focus. The speed on the new lens is on par with the 23mm f2, which I personally believe is the fastest auto-focus prime, Fujifilm has released. There is no auto-focus hunting like on the 56mm f1.2 and low light auto-focus is on par with the best Fujinon glass out there.
Although still very quiet, the auto-focus is a tiny bit more noticeable but nowhere close to the old 35mm f1.4 or 56mm f1.2. I'm really nit-picking here! Overall I'll call it quiet, but not 100% silent.
The new 50mm is very sharp across the frame; including at wide open apertures. Corner sharpness is sharp; very similar to the 23mm f2 and sharper than the softer corners of the 35mm f2. Whatever decrease in sharpness there is in the extreme corners, is completely gone at f4.

MINIMUM FOCUS DISTANCE
At 39cm (15.3 inch) the minimal focus distance is slightly more than the 35cm of the 35mm f2 lens; in line with the expectations of a longer focal range and still enough for some close-up photography; obviously not for macro work.

As can be expected for a normal (standard) lens, the distortion is minimal. A classical shot of a brick wall (focus at 1 meter) can be seen below; RAW shot, no perspective correction done.
