Quick answer
SquareHood spare lens caps are model-specific—choose the one that matches your lens or camera model exactly, not the hood shape.
Why model matters more than hood size
SquareHood lens caps are designed to fit specific lens or camera models, not generic hood dimensions. A cap that works with a Fujifilm XF 23mm f2 may not fit a Summicron 35mm v3, even if both use a SquareHood. Always check the compatibility list before ordering.
The trade-off: precision vs. versatility
Because each cap is tailored to a particular lens or camera, you get a snug, secure fit that generic caps can't match. The downside is that you can't swap caps between different SquareHood setups. If you own multiple SquareHood-compatible lenses, you may need separate caps for each.
How to choose the right cap
- Identify your lens or camera model: Look at the markings on your lens or camera body. For example, 'XF 23mm f2' or 'Summicron 35mm v4'. Write down the exact model name before shopping.
- Match the cap to the model, not the hood: SquareHood spare caps are listed by compatible lens/camera, not by hood version. If you use a SquareHood on a Ricoh GR III, select the Ricoh GR III / IV cap. Ignore the hood's appearance—focus on the compatibility list.
- Check for rear cap needs: Some caps (e.g., for Ricoh Glass) are rear caps. Verify whether you need a front or rear cap for your setup. Rear caps protect the camera's sensor side—don't confuse them with front lens caps.
