What filter size does the Viltrox AF 28mm f/1.8 take?
The Viltrox AF 28mm f/1.8 takes 55mm screw-in filters — its front filter thread is 55mm. Any standard 55mm UV, polarizer or ND filter screws straight on.
The Sony E version of this lens takes the same 55mm thread.
Thread sizes verified 2026-09-03 against per-mount lens specification tables and, where no such table exists (L-mount), the manufacturers’ own published specification pages, matched brand-strictly to our lens index. Lenses whose thread we could not uniquely verify are left out rather than guessed — coverage grows as verified data lands.
