I have rarely missed shots due to chimping, but have been frustrated on occasion with shutter lag and waiting for the camera to record the image on the CF card. Although it is rare in my use of digital cameras, I can understand the interest of some folks in fast 3 or 5 frame burst modes with digital cameras, and the freedom afforded by film cameras in this regard- shots as fast as one can cycle the film advance or motor drive. Normally, when I am in shooting mode, I am "in the moment", and not interested in chimping.
