Originally posted by coreyhkh Has anyone tried these, the ones in my local Camera store are $400 to $600 seems alot for a tube of metal.
I have one of them and I got it from one of the chinese/japanese retailers on ebay for $89.00 I think. I've had no issues so far and since I didn't spend $500.00 I have no complaints. The knob that clamps the lens plate could be a little more robust and if I found one of the bottom pieces from a different manufacturer I might switch it out for a better knob but that has been my only complaint.
Ultimately for me it comes down to if I can take better photos or not and this piece of equipment improves my picture taking ability with a 400mm and 600mm lens.
