Pentax DA 21430 70mm
85 out of 100 medium confidence 12 reviews
The Pentax HD DA 70mm f/2.4 Limited is a compact prime lens that delivers outstanding sharpness, beautiful color rendition, and smooth bokeh, making it ideal for portraits and travel photography. Users praise its weather-resistant build, fast autofocus, and the retractable hood, though some note it can be a bit long on APS-C cameras for tight spaces. The HD coating improves flare resistance and color transmission compared to the older SMC version. Overall, it is highly recommended for Pentax shooters seeking a high-quality, portable telephoto prime.
