Three years in, and the Sony A7iii is still one of the best mirrorless full-frame cameras you can buy. Featuring a 24.2MP Exmor R BSI CMOS sensor, 4K at 30fps and an autofocus system that still feels advanced, Sony’s A7iii has impressive specs. But it also taps into a constantly growing pool of third-party and Sony-built lenses. The A7iii’s popularity now means there are a good amount of both first- and third-party accessories for the Sony too.

Sony NP-FZ100 Battery
Price: $89.86

The A7iii features just over double the battery life of its predecessor, but that doesn't mean you shouldn't have a spare battery or two just in case. Each NP-FZ100 battery features over 700 shots of power, so having at least one in your bag gives you around 1400 in total - enough for a heavy photo shoot or solid day of picture taking.

The Sony A7iii features two SD card slots, but one of them uses a slightly faster UHS-II standard. And while the improvements in speed are less obvious if you're shooting in jpegs, if you're shooting RAW files, you'll find the A7iii's buffer is slightly faster to clear.

The A7iii's compact footprint makes it ideal for travelling with but not so good for actually shooting; those with larger hands may find the Sony's hand grip only big enough for three fingers, which isn't ideal. Enter Sony's grip extension. At around £100, it's not cheap but it extends the grip just enough for a more reassuring feel in the hand - especially with larger lenses. The only catch? Aside from the price, using the grip will stop the camera being able to sit flat.

People are understandably wary of using third-party products, but we think this Meike grip extension is a sensible exception to the rule. Just like the Sony grip, the Meike adds some extra length to the handle to make shooting more comfortable - and like the official grip, it contains no electronics and connects via a screw. Unlike the Sony grip, you do need to remove it to change batteries, though.

The A7iii's USB-C connection makes it compatible with a range of third-party cables - but Sony doesn't actually include a dedicated battery charger in the box. Instead, you're forced to charge batteries in-camera. Getting Sony's battery charger speeds up the charging process, and also lets you can use the camera with another battery in the meantime. At £84 it's not cheap, but it gives you the peace of mind that third-party accessories just can't.

The A7iii may look dainty, but a largely metal construction means most of it will take a knock without falling to pieces. However, the touchscreen is weak point, and it's worth protecting it. This Komet protector does a decent job, and actually has two in the pack. Apply one just as you would a smartphone screen protector, and it'll ensure the back of your A7iii is safe against scratches and scrapes.

If you're a heavy-use shooter and want to improve the A7iii's ergonomics, it's worth looking at Sony's own battery grip. At over £200, it offers double the battery life and adds a chunky grip that's useful for both landscape and portrait use.

Unlike the A7Siii or A7Riii, the A7iii is a strong all-rounder and offers 4K and 30fps as well as punchy 24.2MP images. This Smallrig Camera Cage helps the A7iii unlock its potential for film making, giving you a range of mountings for accessories whilst still allowing access to all the important ports and switches.
