Sony's revolutionary constant f/2 standard zoom — 28-70mm at f/2 with GM optics, a world first.
The Sony FE 28-70mm f/2 GM launched in 2024 as one of the most ambitious zoom lenses ever made — a constant f/2 aperture across the standard 28-70mm range. It effectively replaces 28mm, 35mm, 50mm, and 70mm f/2 primes with a single zoom.
Optically extraordinary — delivers outstanding sharpness across the frame with the dramatically shallow depth of field that f/2 provides at each focal length. XD Linear Motor AF is fast and precise. Minimal focus breathing. The bokeh rendering approaches that of fast primes.
Sony FE mount with 95mm filter thread. Approximately 918g — heavy but remarkable for constant f/2 zoom capability. Weather-sealed construction. 11 rounded aperture blades. Aperture ring with de-click. Fluorine coating. Minimum focus distance 38cm.
Very new — limited used availability at luxury pricing. Nothing else offers constant f/2 across this zoom range with autofocus. The weight and filter size are the main compromises. For photographers who want maximum subject isolation from a single zoom — wedding, event, and portrait professionals.
