Canon EDI6CAN2870RFSTMP1 28-70mm
A constant f/2 aperture across the entire 28-70mm zoom range delivers prime-like light gathering and depth of field control, eliminating the need for multiple fast lenses. The optical design incorporates Ultra-Low Dispersion glass and a fast, quiet ring-type Ultrasonic Motor, paired with a customizable control ring for direct exposure adjustments. This lens is best for portrait and event photographers who need extreme low-light performance and subject isolation without switching primes, despite its substantial 2068g weight.
