Romeo - Personally, if I were you, I'd wait for Canon's next 1D upgrade. I've shot at Tropicana Field with my MkII and never pegged ISO so you should be OK with your MkIIn. From rumors I'm hearing Canon plans to market a gee whiz upgrade in the near future -- perhaps even before end of this baseball season. Mind you, it's only a rumor, but I fully expect they'll fix the AF issue in the next upgrade. I've only shot six games with my MkIII and never in any heat -- as I understand it heat causes MkIII AF problems in poor copies. So the jury's still out on any AF issues for a few more weeks. As for Disney, I probably won't shoot the Ray's games there. I honestly prefer to shoot minor league baseball -- there's not much money to be made in it but it's a hassle free environment unlike a lot of major league ballparks.
Mark - I could probably get better results if I tweaked curves a bit. I'm probably just in a rut and a bit adverse to change -- I'm a bit old school myself. I finally upgraded to PSCS3 the other day and next time I get the time I might fiddle with curves a bit. Thanks for the suggestion.
