Need a low shutter lag point and shoot digital
Hi. I need some help. I want to get a small
point and shoot digital camera, but I am concerned about the shutter lag. Please do not recommend a DSLR, as I have a Canon 1D Mark II and 10D cameras and plenty of lenses to go with them. I'm looking for something small, some specs that are important to me: 5 megapixels or larger, auto, manual, aperture priority modes, 3x optical zoom minimum, with autofocus, built in flash, compact flash I (and type II would be nice) cards, under about $500, reasonably low shutter lag for this type of camera. Nice but not necessary: raw mode output. The question is, what is a reasonably low shutter lag on such cameras these days? I can't seem to find many specs. Lag only seems to be mentioned rarely in reviews, and the manufacturers do not seem to give it. Does someone know of a site (especially a table that compares the lag times, measured in a uniform way) with lag times? I want lag time from shutter press, autofocus, exposure calculation to release of the shutter, and I do not consider lag time with manual focus to be relevant for my purposes. I have a Canon G1 and shutter lag is awful. It often seems to take 0.5 to 1 second or longer to acquire focus and shoot. (Of course this is quite maddening after using the 1D Mark II with its 40 millisecond lag ;-). One camera that I am looking at is the Canon A95, but I can not find shutter lag info. It also only uses compact flash type I. Any help would be appreciated, Thanks in advance, Roger photography, digital info at: http://www.clarkvision.com |

I'm looking for something small, some specs that are important to me: I'm no expert on any of this, but one thing to make sure of is that you can turn off the flash. If you need to make multiple sequential shots, charging a flash can be a limiting factor rather than shutter lag. Likewise, if you _need_ the flash, make sure that you check the specs for flash charge time. -- Steve Gray |

(Of course this is quite maddening after using the 1D Mark II with its 40 millisecond lag ;-). Even if you can find the specs, the formal definition of shutter lag excludes the AF time. The P&S cameras use the CCD for AF and have to read out several frames to focus. So the fastest P&S is going to be a lot slower than the slowest dSLR. Even worse, the CCD-based AF systems often focus on something contrasty in the background instead of your subject. This makes the EVF cameras attractive, since you can see when the AF is messing up.

I should have said "focus on something other than the subject when the subject has relatively low contrast". It's _really_ irritating. As I understand it, the dSLRs can do that also, but the AF sensors are quite a bit smaller so it's much less of a problem (if you select the AF sensor manuallyg). David J. Littleboy Tokyo, Japan |

Remember the camrera doent know what the subject is, only the photogrpaher does. |

It would focus on the pavement at my feet even though the center 1/3 of the image was all a long way away. Remember the camrera doent know what the subject is, only the photogrpaher does. Yes, but that's not the only/major problem. You careful place the (single) AF point over the subject but the camera finds something in the background or foreground to focus on. The focus area in a lot of P&S cameras is just too large. David J. Littleboy Tokyo, Japan |
