I use this for just about everything I need that can use a mount. I've had several of these mounting plates for a while. They are solid, won't rotate, and definately won't slip apart. The locking feature is positive and works. I did have couple of the RC2 and RC0 plates for other things, I gave those away. If you have expensive gear, get something that works and won't let you down. This plate system is it.
Same great quality found in all of the Bogen-Manfrotto products.
Pleased with product. Professional build for heavy duty. Supports heavy lens and DSLR camera.
The salesman that I ordered the Bogen tripod adaptor suggested an extra mounting connector, I acepted - ordered two more connectors. Instant placement of camera on tripod. VERY stable and strong. If you have a Bogen tripod adaptor and have lens that have a mounting foot - buy the extre connectors!
I definitely like the tripod head itself, as it performs like a much more compact version of the 229, so it's strong, with independently adjustable axes, great for large format field work. The tripod plate however, is kind of unnecessarily large, as well as a little awkward to mount to the head. I really have to double check that it's on properly to feel comfortable with this QR plate. I think Manfrotto has, since I bought mine, come out with better, smaller tripod heads that use better, smaller plates. I'll keep this head, but if I lose or break it, I'll go a different direction.
