Sony A7 IV

SanDisk Extreme PRO 128GB SDXC

200MB/s read, 90MB/s write — fast enough for 4K video and deep RAW bursts on any camera here.

The card is the one accessory nobody should cheap out on. A slow card turns a 30fps camera into a 6fps camera the moment the buffer fills.

Spare battery — Sony NP-FZ100

For A7 III/IV, A7C II, A7R V, A6700, FX3.

One spare is the minimum. Cold weather roughly halves what the camera claims.

Lens cleaning kit (blower, pen, microfibre)

Air blower, carbon lens pen, and microfibre cloths. The three things that live in every working camera bag.

Dust on the front element is the most common cause of soft-looking images from a perfectly good lens.

Peak Design Slide Lite strap

Quick-adjust sling strap with anchor links. Swaps between bodies in seconds.

The strap in the box is the first thing most photographers replace. This is the one you buy once.
