The 24-70mm f/2.8 GM II is a standard zoom that resolves like a prime at working apertures. Corner sharpness stays high from 24mm through 70mm, and the 11-blade aperture renders out-of-focus areas with smooth, even falloff. That is why it can stand in for a small prime kit during a paid shoot.
The near-silent XD autofocus is the other standout. It tracks moving subjects during event coverage and switches smoothly for video, with no audible hunting in low-contrast scenes. The A7IV body handles the AF system well, making this a strong partner for hybrid shooting. For a wedding photographer moving between a posed portrait and a walking shot, the focus response stays immediate without constant re-acquisition.
At 695g, this is a light lens for its class. It balances on the A7IV without the front-heavy feel of earlier 24-70 f/2.8 zooms, so an extended day of handheld photo and video work doesn't turn into a shoulder workout. Third-party 24-70 f/2.8 zooms have closed much of the optical gap; the GM II stays ahead through AF consistency and this weight advantage.
The 24-70mm span covers the framing used in event coverage: group shots, environmental portraits, and detail work all sit within reach without swapping lenses. The constant f/2.8 keeps exposure stable when moving between bright and dim spaces, which matters more when the light changes between rooms. The moisture-resistant build is another practical advantage for outdoor ceremonies, where the kit is not always under cover.
The case for this lens is not that it is the only sharp 24-70 f/2.8 available. It is the balance of sharpness, autofocus, and weight in a single package, which fits the A7IV's hybrid body better than a zoom that wins on one spec and gives ground on another. That balance is also what makes it feel smaller than the category implies.
This is the lens for A7IV owners who want one standard zoom for weddings, events, and hybrid photo/video work. The main boundary is stabilization: there is no built-in OSS, so the A7IV's IBIS does all the work. On this body that is workable for handheld shooting, but it is the tradeoff to know before buying.

Cons
