Review on 📷 Pentax SMC DA Series 16-50mm f/2.8 ED AL IF SDM Lens: Wide Angle Zoom for Pentax Digital SLRs by Kenta Kawano ᠌

Good lens in terms of optical qualities. Chromatic aberrations, although present, rarely interfere strongly. The weak side is constructive. They could make the top lens of the system more reliable. To move the lens block on the zoom ring, a carbon fiber stop! At a time when competitors have steel there. Its pros: Color rendition. Working aperture 2.8. Nice drawing. Relatively fast focusing speed. Quiet. Dust and moisture protection - filmed in rain, snow, in a sandstorm. All without consequences. Has some cons Lens chromate. Very flimsy design. After 1.5 years of operation, the zoom ring backlash appeared. After 2.5 the ring just began to scroll. Due to the wear of the mechanism, a repair is required at almost half the cost of a new lens . The price for it in 2022 is greatly inflated.
