The Pentax SMC DA L 50-200mm f/4-5.6 ED WR is a budget telephoto zoom for Pentax APS-C DSLRs with weather-resistant sealing. The DA L designation indicates Pentax's lightest, most affordable tier. Covering 75-300mm equivalent.
Optically basic — acceptable centre sharpness but soft at 200mm. ED glass helps control chromatic aberration. Weather-resistant construction is unusual at this budget tier — a Pentax advantage for outdoor shooting. Body-driven screw AF.
Pentax K mount with 49mm filter thread — very compact. Approximately 255g — incredibly lightweight. Weather-resistant WR sealing. DA L — lightest Pentax lens tier. APS-C coverage. In-body SR compensates for lack of lens stabilisation.
Available used very cheaply. The weather-resistant sealing at this price is a genuine Pentax advantage. The DA L build is basic plastic but functional. The HD 55-300mm PLM WR is much better. A functional budget telephoto for outdoor Pentax shooters.
