Hector Javkin Posted August 24, 2018 Share Posted August 24, 2018 I ordered a Sigma 150-600mm Contemporary lens which is scheduled to arrive tomorrow, and will need to test it fairly soon. If you have one of these, and use an A-S compatible head clamp on it, what plate do you attach to the foot? It seems that neither Kirk nor RRS make custom plates for it. My A-S tripod head has a non-removable clamp. I will be grateful for any suggestions. Link to comment Share on other sites More sharing options...
Ed_Ingold Posted August 24, 2018 Share Posted August 24, 2018 The best approach is a replacement foot (and ring, if possible). Short of that, RRS and Kirk make long plates with a lip on one short side and an elongated slot for the screw. I use them on several lenses (and Hasselblad cameras). They aren't theoretically as solid as a fitted plate, but in practice they stay tight and don't twist. Link to comment Share on other sites More sharing options...
Hector Javkin Posted August 24, 2018 Author Share Posted August 24, 2018 Thank you. It seems that the long plates are all that KIrk and RRS offer. I haven't seen a replacement foot, or the complete collar and foot with the A-S compatible channel. Link to comment Share on other sites More sharing options...
Ed_Ingold Posted August 24, 2018 Share Posted August 24, 2018 I replaced the entire ring and foot assembly on a Nikon 400/4 AF-S. The original was worse than useless. Higher-end zooms often have an easily removable foot, which is an opportunity for RRS or Kirk to step up to the plate (pun intended). There's nothing wrong with an add-on plate, other than bulk.

Hector Javkin Posted August 24, 2018 Author Share Posted August 24, 2018 I did the same on a Nikon 300mm f/4 AF-S. Years later, when I bought a used Nikon 80-400mm, the collar and ring were missing. That not only saved me something on the purchase price, but also the need to test for stability before buying a Kirk replacement. I hope Sigma has done better on the lens scheduled to arrive at my house today. Link to comment Share on other sites More sharing options...
