The camera can shoot up to 10 frames in one second burst when you hold down the shutter button in burst setting.
Another feature you might like with a new baby is being able to get the always missing photographer in the shot using the Automatic shooting with Self-portrait timer Point the lens at yourself so that the selected number of faces are reflected in the screen. The shutter operates automatically.
And of course you can always switch it to full 1080 high def video mode and shoot great video also....
It is very fast depending on the settings you use. One setting takes a little longer, but it's understandable because that setting is for really "high quality" pictures that you would "set up" for. The other settings are very quick. Overall, the camera is phenomenal. The colors are great and it makes the necessary adjustment to focus well. I love it!!
Much quicker than any other digital camera I have ever owned. Almost instantaneously. It does have to re-load after every rapid shot sequence (when you set it to take 10 shots automatically in a few seconds). The re-load takes about 5 seconds or so. Very clear pictures. The zoom feature is amazing and very stable.
If you don't need the absolutely highest resolution, you can record video, and in the playback screen, you have the option of converting the exact moments of the video into still pictures. The capture rate shooting video would be faster than any burst mode in picture mode, so you'd probably get the moment you're looking for even with a really high speed baby.
