Somebody, perhaps Marnie, was asking about a 300D which was experiencing an "8-9" second shutter lag. I hope this is a mistype! I didn't originally think much of it because I wouldn't expect much of a camera like the 300D.
Then it occured to me, if 8-9 seconds rather than .8-.9 seconds is what was meant, that you could shoot the equivalent of TWO ENTIRE ROLLS through an EOS1Dmk2 in that time. Even at .9 seconds you could get 6-7 frames off. The shutter lag in pro DSLRs is down to substantially under 100ms according to the manufacturers. If they could only make a little better pellicule mirror there would be nothing really stopping them from a 15fps DSLR, especially if somebody figures out how to get the shutter out of the loop too. On the "all about the glass" topic, I know a number of action shooters who switched from Nikon to Canon primarily because of the extra frame rate. One of my buddies tells me that he "always gets the ball in the picture" now at 8fps. Canon glass isn't bad, but increasingly I think that it's all about the cameras. Hopefully that'll help the *istD which is a good camera for its price class. DJE
