Note for Sigma Lenses:
The above recommendations assume that the standard factory foot is installed on the lens. It has come to our attention that Sigma sometimes installs their larger TS-41 Replacement Collar and Foot on their lenses. We suggest that you measure the length of the foot on your lens to make sure that our suggested plate is correct (the plate should be about 1" longer than the foot on your lens).
Please note ? - Lens has the option of using a standard plate, or a replacement foot.
The replacement foot (e.g. AP-554, AP-602...) is the lightest, most compact solution, and it is the mandatory choice if you are using the Wimberley Sidekick. However, the standard plate (e.g. P-50, P-40...) allows you to keep your factory lens foot in place, and provides a better handle for carrying your lens.
