Ok, I have noticed I am getting some out of focus images even with tripod mounted shota and a remote shutter release. If I use mirror lockup it made a world of difference (using a 5D and 300mm with a 1.4 converter). I have good legs but I have been using a three way Culman head from my older junkier tripod (because I had the quick change plates). I am thinking it is no longer up to the task. Any recommendations for a good replacement? I am thinking $100+ but I don't know if that is plenty or not near enough cash for something decent. I don't even know where to begin looking so any guidence is much appreciated. Mostly landscape, gradually doing more wildlife. Looking into a 1 series body upgrade too which may have a little more heaft. Weight is an issue, but not a total limiting factor. Can anyone point me in the right direction with articles, links, reviews, and or maybe a specific recommendation?
