I'm pretty sure I'm going to return my just purchased P1 in for a PL1. The thing is that I really didn't think that flash would be a big deal, but after working with the P1 the other night, I could see that indoors it would be a HUGE deal. I would most likely not even be able to go to a party and if they light wasn't great take pics. That could be a deal breaker. I've seen some exhaustive tests of side by side with the P1,P2 ad PL1 and my eyes are telling me it is sharper (via the supposed lighter AA filter) and without question has less noise at higher ISO's and shows retention of resolution better up at ISO 800 and 1600. I most certainly would NOT be shooting this camera at ISO 6400 so it's a non issue. Also the 1/2000th sec shutter speed limitation could be mitigated by a ND filter or CP filter for what I'd use it for outdoors. All in all I think it's the best thing for me to do. I haven't spoken to other owners of it other than 2 dealers I respect and BOTH have stated emphatically it is faster to lock focus than the previous models. Either way I just think it must be a better move for me. Are there any strong dissenting opinions here?
