Camera Accessories: Cards, Lenses and Batteries

Memory card type, capacity and speed rating

Memory cards are the most common accessory here, and three choices matter. First the format: full-size SD, SDHC and SDXC for cameras, microSD for action cameras and drones, as your camera's manual specifies. Then capacity, from 32 GB to 1 TB, where SDXC covers 64 GB and above. Finally speed: UHS-I U3 and V30 suit 4K video, read speeds of 100 to 160 MB/s speed up offloading, and write speed is what limits recording.

Lenses, batteries and the model-specific rest

Beyond cards, most accessories are cut for particular cameras. Interchangeable Camera Lenses must match the body's mount, and filters match the lens thread size. Batteries use model codes such as NP-FZ100, so confirm the code, and chargers must match the battery type. Cables and remotes depend on your camera's ports. Start from your camera's exact model name; see Camera Batteries, Grips & Chargers.

Questions about Camera Accessories: Cards, Lenses and Batteries

What is the difference between U3 and V30?

Both mean a minimum sustained write speed of 30 MB/s, but they come from different rating systems: U3 is the UHS speed class and V30 is the video speed class. Cards often carry both marks.

Can I use a microSD card in a camera with an SD slot?

Yes, with a microSD-to-SD adapter, which some cards include. Make sure the card's speed class suits the camera, because a poor adapter can limit speed or cause read errors.

Will a third-party battery work in my camera?

Often yes if it has the same model code and voltage, but results vary: capacity can be overstated, and some cameras show a warning or hide battery readouts with non-original cells. Choose a battery that states your exact camera model.
