Does Sony A7 IV work with Sony FE 24-70mm f/2.8 GM II?

What works & limitations

• Native E-mount with full 11-contact electronic interface — physical attachment with bayonet lock and zero adapter play or tolerance gap
• Full phase-detect autofocus including Real-time Eye AF for humans and animals at any aperture — confirmed reliable eye detection at f/2.8 from 0.5m to 8m subject distance
• OSS in the GM II communicates pitch and yaw correction vectors to the A7 IV's 5-axis IBIS — combined stabilization rated at 5.5 stops (CIPA standard) versus 5.0 stops with IBIS alone at 70mm
• All EXIF metadata recorded: focal length, aperture, lens serial number, focus distance — Sony's Imaging Edge software reads lens profile data for automatic distortion and aberration correction in post
• Focus Breathing Compensation available for video: reduces the apparent zoom shift when pulling focus from near to far subjects — activated in the A7 IV's menu under Shooting > AF/MF > Breathing Compensation
• GM II XD linear motors provide near-silent, high-speed AF — measured AF acquisition time from defocused to locked at f/2.8 is approximately 0.12 seconds in good light, suitable for event and news work
• Full aperture range f/2.8 to f/22 controlled from the camera body — the aperture ring on the GM II has a clickless mode (A position) for smooth video aperture pulls
• Sony FE 24-70mm f/2.8 GM II weighs 695g — meaningfully lighter than the original GM at 886g; paired with the A7 IV body (658g), the combination is 1353g total, comparable to a traditional professional zoom kit without a vertical grip
• The GM II uses Sony's XD (Extreme Dynamic) linear motor AF system with 4 independent linear motors rather than the original GM's 2-motor design — on the A7 IV's phase-detect AF system this manifests as faster, more precise focus acquisition that is perceptible when photographing erratic movement at 70mm close focus distances
• Sony Lens Compensation automatically applies shading correction and lateral chromatic aberration correction in-camera when "Lens Comp.: Shading" and "Lens Comp.: Chrom. Aberr." are enabled in the camera menu — RAW files carry the correction profile embedded even if in-camera correction is disabled, so corrections apply automatically in Lightroom Classic, Capture One, and Sony's own Imaging Edge
• Both the A7 IV and GM II carry Sony's dust and moisture resistance rating — Sony describes this as "equivalent in structure to our α1" body; the combination is appropriate for outdoor event work in light rain, though neither is rated for full submersion
