Looking for a DSLR that doesn't have a "lag" time after pushing the shutter button.

With my "old" film SLR cameras (Pentax MX and Mamiya RB67) I got the image I visualized when I pushed the button. With the new DSLR's there seems to be a slight lag time from pushing the button to grabbing the image. Are there any DSLR cameras that are as fast as my "old" cameras?

Well, most DSLRs these days allow you to press the button down halfway or all the way. Halfway press gets the focus and full press gets the picture.

Does it lag even after getting the focus?

I know my Rebel XT won't even shoot if I don't press the button halfway down first to get focus.

Thanks for your prompt reply and info. I have not purchased a camera yet. I've tried friend's cameras and at the store. With my film SLR I would be adjusting the focus manually while tracking the subject.
When you push the button half way down can you hold it there? With the camera keep adjusting the focus as you hold it in the halfway position? Or is the focus a one time deal?
Perhaps I just need to get a camera and refine my technique, just like I did many years ago with the SLR.

If you go try again it's very obvious the half press is very easy and the full press takes a little more effort. And yes you can hold down the half press very easily.

And the half press usually focuses one time but it'll depend on the camera and settings you use I believe.

yeah, the speed (lag) is going to be more a function of how the focus mode is set, and whether it's "focus priority" or "release priority". usually continuous focus is release priority.

the more pro-level cameras are going to have a slightly shorter lag time, but even amateur DSLR stuff is going to be quite fast IF it's set to the right focus / release mode.
