Product Details

smc PENTAX-DA★ 50-135mm F2.8ED [IF] SDM

This is a modified lens where the AF drive has been changed from SDM to an in-body motor drive. Pentax's SDM drive is prone to failure, so changing to a motor drive ensures reliable AF performance.

This is a telephoto zoom lens, part of Pentax's premium (Star) lens line, featuring a constant F2.8 aperture and excellent color reproduction and resolution. It's considered one of the big three constant aperture zooms.

On APS-C size cameras, it provides a focal length equivalent to approximately 75-202mm in 35mm format.

I used this lens on my K-3ii and K-5ii (APS-C) digital cameras, but I am selling it due to equipment consolidation.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
