LENSband on Sigma 70-210mm f/3.5-4.5 APO FD BL
If you've ever experienced zoom creep with a lens, LENSband is an affordable, easy, and effective way to solve the problem. I tested it on a Sigma 70-210mm f/3.5-4.5 APO FD BL lens I recently purchased from Ebay. The push/pull zoom was a little loose and would move when the lens was pointed downward. The LENSband i ordered from www.lensband.com came quickly in the mail, and as soon as I put it on the lens the problem was solved. The band creates just enough friction between the barrel of the lens and the zoom to keep it from creeping, yet still allows you to focus easily. A very simple yet effective product. I highly recommend it.
