XCSOURCE® flat quick trigger QR + Metal clamp with 1/4 "adapter to 3/8" monofrotto Benro B-1 tripod ball J1 monofrotto Arca Swiss Ball Tripod Tripod DC463 (Electronics)
Solid, quality, quick and easy to use. The finishes are perfect. There bubble levels. I use it for my Canon 7D. The set is perfectly suited to a very old Hama ball that I use for a long time and I wanted to keep. No plastic, great for bourins! RAS fo
