The AP-553 does not provide enough length for proper balance when using the certain light weight camera bodies (see chart below). If your lens/camera combo is not compatible, use the new AP-554 foot.
For Nikon: 500 f/4 AF-S versions I & II, & VR 200-400 f/4 AF-S VR
Dimensions (Overall L x W x H): 5.7 x 1.5 x .9 in Weight: 5.3 Oz (plate, mounting screws ,& stop screws)
This plate (AP-553) has been replaced by the AP-554, which provides a better handle to carry your lens by and is longer, allowing you to balance your lense with lighterweight camera bodies. However, we are still selling the AP-553 as a less expensive & lower profile option for those who have heavier camera bodies (see chart below for campatibility). If you meet the requirements of the compatibility chart below, and want the lowest profile and most ridgid plate possible this plate is a good choice.

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 that the foot on your lens).
