I would like to use the arca-swiss style clamps and plates with my Sony a850 and my Manfrotto 410 head. I have a couple questions for anyone who has accomplished this or something similar.
1. What's the best way to get arca-swiss style clamp onto the 410 head? I've seen the Kirk 3271 adapter and seen mention of screwing a RRS clamp directly to the 410 with the 410's qr lever removed for an extra hole.
1a. How solid/secure is the Kirk adapter? Does it attache directly to the head, or use the plate that comes with the head?
1b. What RSS clamp has the right hole spacing to attach to the 410 head? Or should I just attach a clamp to the manfrotto plate (is this secure?)?
2. What plates fit the a850? I know there is an L-plate by RRS. Is there a standard plate (non-L) by anyone? Do the Kirk or RRS "universal" plates work well? What do you use on your Sony a850/900?
Thanks for any insight, experience, and examples.
