    28–70mm · f/2–20

    Overview

    The Sony 28-70mm F2 GM is optically exceptional, delivering sharpness comparable to primes, especially at 50mm. Weaknesses include high vignetting at f/2 and large 86mm filters. Build is solid, weather-sealed, and lighter than Canon's rival at 918g. Autofocus is fast and accurate. It suits portrait and wedding photographers needing f/2 versatility, though it's heavy and expensive ($2,900).
