I switched to Arca-Swiss QR system from the Manfrotto RC2 about 17 years ago
and have never looked back. The A-S system is far more precise and secure, even
if it is slightly less convenient to fit and load. The problem with the
Manfrottol RC2 is that the plates have a small amount of play in the clamps
that make precise positioning difficult ... Enough so to really annoy at some
point ... Where nothing like that exists in an A-S clamp and plate system.
You folks may remember that a couple weeks after I bought my K-20 I had
it and my sigma 50-500 on a monopod with an RC2 clamp, which then
released can dropped my camera and lens on the pavement. Nope the RC2
are not secure, I trust the Arca Swiss much more.
