Just a quick question about this camera. In manual is it fully manual? Can you pick any combination of iso, shutter speed, and aperture? I have a GA645 and really don't like the fact of f8 being the largest aperture you can use at a certain iso (1000 and up) when using the camera in manual, for example. It assumes you will use flash! Does the GA645zi do the same thing?

just set my ZI to ISO 1600 and changed to Aperture Priority --> let me set from F4.5 to F22. In manual mode same result. I don't have your camera, not sure why it would not allow to set the complete range.
Yes in manual it is full manual. The default for the dial is aperture. You need to push the +/- button while turning the dial for speed.

Manual is fully manual, and quite comfortable - aperture is directly set on the up/down dial (a.k.a. thumb wheel), time is set on the same while simultaneously pushing the exposure compensation button in front of it with the index finger. Manual focus however is barely accessible, being combined on dial and AF/M button - where the latter is down at the back below the display, placed in a groove for protection against accidental pressing. It takes a fingernail or other pointy instrument to press it - something I can't do while looking through the finder.
WTR the f/8 limit, it is even worse, at f/11, due to the zoom lens. 1/700s can only be combined with aperture f/11 and below, in any mode including manual - at that speed the shutter does not fully open and limits the lens diameter. All other shutter speeds are not restricted.
You better consider that shutter a 1/400 shutter with a limited extra speed - which is good enough, or indeed even better than usual. Only the fast among my leaf shutters (and as a mostly medium and large format photographer I have plenty of them) claim to do 1/500, and most of them actually test slower than 1/400 (most manufacturers already took use of the permitted -1/3 stop tolerance to start with, and they lose speed as they age), so a real 1/400 with 2/3 stop reserve stopped down is quite good.

Not at 1/700!

I never mentioned what the shutter speed ended up when you went from one end to the other in Aperture Priority or full manual mode. I was mainly responding to the OPs request for info and F stops range. Anyway you answered his question in a more complete manor in your post.

Thanks for the responses. Helps out a lot.
Not sure why the GA645 has its limitations in manual. I actually found out here: someone posted thinking their camera was not functioning properly. I looked at mine and it did the very same thing.
