SMC Pentax-M 28mm f2.8 brand_Sekonic It incorporates Nikon’s quick AF-SSo we're right up front about it: This lens has a stiff aperture control ring. No, that's not how it's supposed to be, but that's the way it is. However, the glass is clean and imaging is excellent. If you don't mind a bit of extra exercise when you're changing apertures, this is a nice little wide angle lens in otherwise fine shape.
