Duplicate of Pentax's DA 35mm f/2.8 Macro Limited — same lens as ID 3870 without HD designation.
The Pentax SMC DA 35mm f/2.8 Macro Limited is an earlier production version of the lens described under ID 3870, with the original SMC coating rather than the later HD coating upgrade. It provides the same 53mm equivalent with 1:1 macro capability in the premium Limited aluminium body. The optical design is identical — only the coating differs.
Optical performance is very good — the same optical design as the HD version. Macro sharpness is excellent. At normal distances, the lens delivers sharp, contrasty images. The SMC coating provides good but not quite as refined light transmission as the later HD version. The differences are subtle and most visible in high-contrast backlit situations.
Pentax K mount, APS-C (DA). Filter thread is 49mm. Weight is approximately 124 grams. Build quality is outstanding Limited series machined aluminium. Available in silver and black. Benefits from Pentax body SR stabilisation. Screw-drive AF. The Limited build quality remains exceptional regardless of the coating generation.
Available on the used market — typically slightly cheaper than the HD version. Check focus, cosmetic condition, and confirm whether SMC or HD coating. A premium compact macro prime regardless of coating version. The differences between SMC and HD are subtle. Same excellent lens as ID 3870.
