Does anyone out there have first-hand experience with the DA20 "Action Finder" for the F4, or I guess on any other F body for that matter. I bought a beautiful used F4 w/o a finder. I have a standard finder (DP20) on my other F4. I don't actually shoot much action. I'm more of a landscape/macro/general nature photographer, but I'm intrigued by the great eye releif offered by the action finder. My local shop doesn't have one I can try - and I'm not shy about returning one if I buy it and don't like it - I just wonder if anyone has an opinion about them.
