XF 23mm F2.8 R WR vs XF 23mm F2 R WR: pros and cons

Fujifilm XF 23mm F2.8 R WR	Fujifilm XF 23mm F2 R WR
90 g and 23 mm long — true pancake dimensions on every X body. Aperture ring, focus ring, and weather resistance at this size are unusual. 0.20 m close focus and 0.15× magnification beat the older XF 27mm F2.8 pancake. 11-blade rounded diaphragm keeps highlights relatively round stopped down. Designed to resolve for Fujifilm's 40.2 MP X-Trans CMOS 5 HR sensor.	One of the best-value primes Fujifilm sells — Fujicron pricing, metal build. Fast, quiet, confident AF — the quickest-focusing of the small 23 mm options. Colour rendering owners rate the nicest of the f/2 trio. Weather sealed with an aperture ring; 43 mm filters shared with the 35/50 F2. Crisp across the frame once stopped down to f/2.8.
f/2.8 is one stop slower than the XF 23mm F2 R WR. No optical image stabilization — leans on the body's IBIS when present. DC motor AF is not marketed as a linear-motor design. Pancake rings are small and close together; not ideal with gloves. Hood adds bulk and slightly reduces the pancake character.	Soft wide open within ~1 m — the close-portrait weakness that sends owners to the F1.4. One stop slower than the XF 23mm F1.4 R LM WR, with older-generation AF. No optical image stabilization. A full barrel, not a pancake — the 27mm F2.8 is far smaller.
