Small P&S Shutter Lag Times ?
I have been asked to help buy a compact digital camera, and am currently,
with the intended purchaser, making our shortlist of models to look at based on published spec.s and reviews. But as we all know, published spec.s very rarely say anything about shutter lag... She wants a camera that can go with her all the time, so it needs to be small. Main interests are landscape and - the impetus for buying the thing in the first place - a new kitten. So a lens that goes reasonably wide (insofar as they do) would be good, and a bit of reach at the other end would also help. Something of, say, five or six MP up would be enough. And, obviously, for the kitten, minimal shutter lag is absolutely critical. I'm sure this has been discussed at regular intervals, but I couldn't see a recent thread on it, and anything older is likely to exclude many more recent models, so thought I'd ask the question 'afresh'. Any comments or experience on models fitting the above criteria that have either particularly short (good) or long (bad) shutter lag would be very much appreciated. I suppose long start-up time would also be a bad thing, so any experience there would be useful as well. (Models she's shortlisted so far include Ricoh Caplios, various Pentaxes, a Samsung, Olympus, and Fujis, but other suggestions welcome.) Very many thanks (and Happy New Year), Peter -- http://www.bard-hill.co.uk |

Very many thanks (and Happy New Year), Peter The only real effective way to account for shutter lag in a P&S is technique. Pre-squeezing to set focus and exposure... then waiting for the shot. Release of the shutter from this point is instantaneous. Can be problematic if the lighting of the composition changes (kitten runs from shaddow to sun) or the subject changes distance. But the second one is not so bad with many P&Ss because they have decent DoF with the wide angle and relatively slow lens. |

Here's one which is f/2.8 all the way out to 432mm eq. focal length..... http://www.dpreview.com/reviews/spec...ic_dmcfz20.asp David That's not really a P&S... it's more of a zlr or whatever they are calling them these days. The OP said: I have been asked to help buy a compact digital camera, and She wants a camera that can go with her all the time, so it needs to be small. So I'm thinking a traditional P&S. I looked into lens speed quite a bit back in the day, 'cause I shoot volleyball, and was using an OLY 2020Z when I first started. It was pretty good, going from F2 to F2.8, and I was looking to replace it. The current version of this camera is the C-7070, which is F2.8-4.8 This is more typical of today's compact ammeras... the Canon SD900 is F2.8 - F4.9.. The A640 is F2.8 - F4.1 And these are with a max ISO of 400. Slow when off wide angle. My F5.4 guess at full zoom was a bit off, though. |

wrote in message ... http://www.cameras.co.uk/html/shutte...omparisons.cfm They have an interesting definition of shutter lag. "The Shutter Lag Comparison Table shows the amount of time it takes each camera to record one shot and five shots" It is supposed to be the time taken from pressing the release until the shutter operates and has /nothing/ to do with how long it takes to record the image. The table appears to be meaningless as far as shutter lag goes. Anyway most cameras can operate faster if you turn off automatic white balance. It certainly slows mine down. The same is true of auto exposure but its more difficult to live without. |

Too bad that line went to s---. |

The sites use of the word record is misleading. Shutter lag times show ARE for the time taken from pressing the release until the shutter operates. If you'd include the record time also then the times would be much slower than the fast times stated. The table appears to be meaningless as far as shutter lag goes. Not so. The table can be arranged by brand, category of camera, five shot, or one shot lag times. Not electronic record times as you believe. Anyway most cameras can operate faster if you turn off automatic white balance. It certainly slows mine down. The same is true of auto exposure but its more difficult to live without. |
