Duplicate of Fujifilm XF 8mm f/3.5 — same lens as ID 3720 with WR designation confirmed.
The Fujifilm XF 8mm f/3.5 R WR is the same lens described under ID 3720 — Fujifilm's widest prime for the X system. Providing a dramatic 12mm equivalent on APS-C with weather resistance. The WR weather sealing adds dust, moisture, and freeze protection to -10°C. One of the widest rectilinear APS-C primes from any manufacturer.
Optical performance is very good. Sharpness is excellent in the centre. Well-controlled distortion for 8mm. The f/3.5 is adequate for landscape and architecture. The 62mm filter thread at 8mm is a remarkable engineering achievement — enabling standard filter use at extreme wide angles. WR sealing adds genuine outdoor capability.
Fujifilm X mount, APS-C. Filter thread is 62mm. Weight is approximately 215 grams — very compact. Build quality is good with WR weather resistance. The Fuji aperture ring provides direct aperture control. The compact size suits the X system's emphasis on portability. Same lens as ID 3720.
Same lens as ID 3720. Check AF, WR, and optics. An outstanding compact ultra-wide for Fuji X — the 12mm equivalent, weather sealing, and filter thread combination is remarkable. The f/3.5 limits astrophotography. Best for landscape, architecture, and outdoor wide-angle work.
