I had one of these untill a friend lost it. I bought a new Z712 IS which is essentially the same but higher optical zoom.
Fo the image speed, you really need to buy the good high-speed SD cards. If you use the cheap-o ones, you have a looong processing time. Get the PNY or Kingston made for cameras and you are OK. Also get the rechargable battery packs. The RcR-3’s last quite a while and are cheap compared to AA photo lithium. By the way, my instructions say that the camera may malfunction without the proper battery, which means it quits taking pictures or the flash will not work when the AA’s get low.
The only other negatives are no through-the-lens viewfinder. You have a small button to the left of the viwefinder to select LCD screen or finder. The lens cap just presses on, does not snap but you can purchase another one at most camera stores.
Bottom line is - get the right batteries and SD-cards and this is a great camera with a lot of features to keep most average photog’s happy - takes very nice pictures with good image stability. Nice price too, I paid more when i first bought it, and it still runs about 150 local. The Z712 runs about 180 local, 150 on-line (plus shipping),
