Okay here's the situation. I have a Canon 40D, 400 mm f/5.6 lens, 180 Tamron macro, etc. I'm looking for a compact camera that is fairly good for taking closeups of flowers/salamanders/insects, etc. I know the compact job probably won't do as good with macros as the Tamron 180mm, but I need something that will fit in my pocket to carry around. Often, while I'm doing bird photography, I'll come across an interesting plant or amphibian, insect, etc. I'm looking to travel a bit lighter, as I'm tired of switching lenses in the field from the 400 to the macro or the 17-55. Things I'm looking for are: small size, lots of megapixels, good macro capability, video capability (?), low ISO capability, fairly quick shutter. I mention the latter because I had an older Canon P&S and there was a delay from tripping the shutter to when it actually captured the shot. Any help would be most appreciated. I'm open to other brands for a P&S, but since I prefer Canon (at least for SLRs) I figured I'd start here. Thanks.
Oh yeah, since I do a lot of shooting in the woods, I'd like something that can handle low light well and have a good flash. Yikes, I'm asking too much. Reading some reviews now and getting more confused....
Have you considered a system like the NEX or a olympus m4/3 with a dedicated macro lens?
