For sale is my Linhof Profi II ballhead fitted with a Really Right Stuff 60mm lever clamp. The head shows use but everything works perfectly. This is my backup ballhead, which gets no use anymore since I switched to mostly smaller cameras. It weighs ~2 lbs., and is rated for a 17.6 lb. load. The RRS clamp is breeze to use with a lever instead of knob, and it locks down perfectly on a camera plate.
For me the best gear has always been so intuitive and easy to use that you forget it's there, and that's what this is--hands down this is the finest head/clamp combination I've ever owned. Check the specs and reviews from Linhof, B&H or other retailers. Price is $195 obo, which includes shipping and PayPal to the lower 48. US sales only, please.
