Depends on what you mean by that. Shutter lag on recent cameras, like the Fuji F30, is comparable to a 35mm compact AF camera, but not as responsive as an SLR or a manual focus, manual 35mm compact like the Rollei 35S ... but it's close to that one. Most live-view cameras use the main sensor to frame, focus, and evaluate exposure so there are delays if you are pressing the shutter release in one action. If, however, you can lock exposure and focus prior to making the release, the lag is very short and modern cameras with good internal bus transfer speed, coupled with fast storage, move the data to storage very quickly now, reducing shot to shot delay to near zero. Buffered IO in some cameras, like in SLRs, eliminates the shot to shot delay almost entirely. Basically, the issues come down to what the camera has as hardware and what you're willing to pay for it. I hope for something like the DP-1 or the Pentax prototype with the ability to turn off the AF, lock the exposure, and turn off the Live View in exchange for a quality clip-on viewfinder when responsiveness was primary. That would make a great compact. Godfrey -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
