shutter lag time a650is?

I want to know the shutter lag time (when prefocused) of the canon a650is. This is extremely important for me because I take pictures of moving dogs most of the time.

Shutter delay is a way of life in digital cameras. But the delay is lessening as the technology matures. And what's interesting is, that DSLRs dont' have a lag issue at all. Or, it's nearly non existent.

But compact point and shoots, well, they know how to do it, but historically, keeping camera prices low has made it more cost prohibitive. The good news is that according to recent news articles, many camera companies will be incorporating the CCD chips they use in their SLR lines (which give no shutter lag) into their point and shoot cameras. So look for it within the next few years.

Meantime, there are a few tips to speed up your performance:

1. Prefocus. Hold down the shutter half way to get a prefocus of the image you're shooting. When it changes, prefocus again. This will speed up your camera's performance during picture taking since it won't have to autofocus before it shoots the shot. This will speed up your shutter lag time by as much as 80%!

2. Use faster SD cards. Yes, there are faster cards and it does make a difference in writing the image file to the card. This is especially key if you're taking multiple or burst images.

3. Fresher batteries. Use alkalines at least. But I recommend using high energy batteries designed for digital photography. Varta is a good brand. They are usually sold in camera shops, are long lasting (because they are sold in small quantities) put out alot of energy.

4. Shoot in "sports" modes when you're in situations that require action. Night or available light modes when in night time settings. These presets can help in speeding up your shots, rather than the camera taking a split second to evaluate the conditions of the lighting.

5. Pan with the action. You can create some pretty cool shots by panning with your shot, focusing on your subject. This will create the effect of your subject in sharp contrast to the blurry background.

6. Use a flash - even in day time. This will "freeze" the image and cause your subject to "pop" in the shot. However, flash is only designed for limited range and can dissipate outside of about 20-25 feet unless you're using a zoomable flash.

7. Stick with 100-400 ISO. Going higher will cause more noise/grain in your shots, particularly in darker settings.
