Camera lenses: a compatibility checklist before you order

Separate fit from function

A lens that attaches mechanically may not support every autofocus, stabilisation or aperture function on your camera. Adapters introduce another compatibility layer. Read what the maker explicitly supports rather than assuming an adapter preserves all original functions.

Check sensor coverage too. A lens intended for a smaller sensor may have restrictions on a larger-sensor body. Confirm any crop or resolution implications in the camera's documentation before judging the apparent focal length or value.

Choose for the picture

List the subject distance, available space and light. A long telephoto is not a substitute for a wide lens in a small room. If possible, look at the focal lengths you use on your current zoom and identify where you repeatedly reach its limits.

Borrowing a lens for a planned session is a useful way to check whether its size and working distance suit you. Include filter size, hood and carrying weight in your comparison.

Check the listing carefully

• Match the full lens model and mount, including suffixes.
• Confirm required functions with your exact camera body.
• Check included caps, hood and any adapter separately.
