Sony FE 40mm f/2.5 G - Sony E-mount

The FE 40mm f/2.5 G is a compact, weather-sealed prime that sits between traditional 35mm and 50mm focal lengths. It shares the same physical dimensions and 49mm filter thread as the 24mm and 50mm G-series primes, making it convenient for gimbal use. The lens includes an aperture ring, a de-click switch for video, and dual linear motors for fast, quiet autofocus performance on both full-frame and APS-C bodies. When buying used, verify that the aperture ring rotates smoothly and the de-click switch functions correctly. The aluminium barrel is durable but can show fine scratches on the edges. We check for consistent sharpness across the frame and ensure the customisable focus hold button is responsive. SDS confirms the weather sealing at the mount is in good condition.
