Anyone figured out how the 'Pan-Focus' mode works yet?
Assume it locks focus into infinity at the far end, but what's the focus setting for the near end? Is it fixed or auto focus when the subject is close? If auto, what are the near focus range limits? Sony didn't say much about this in the manual.
Or am I totally misunderstanding the intent of this mode, which is a strong possibility! :)
Thanks in advance.

Re: S70 'Pan-Focus' Mode
Panfocus mode on the F505 appears to convert the lens to a fixed-focus design,
(everything in reason is always in focus) presumably by stopping down, and perhaps by doing other lens adjustments.
So "panfocus" must mean "the whole world is always in focus", instead of "quickly focus as you pan", as at least one reviewer has misinterpreted it. This feature is very handy for a couple of reasons. First it eliminates the autofocus
delay, cutting the shooting time down to just the shutter release delay. And
second, it allows for shooting in total darkness, since the image is always in

First check that the camera setup is not in the macro mode, or in a fixed focus mode of some type.
If there is an actual defect, it is possible that the focus helicoid in the lens has some abstruction or defect near to the end of its focus range. It is also possible that there is a fault with the focus sensing for the near to infinity point.
One Shot AF will focus on something and stop the AF process. One Shot AF will not fire the shutter until the lens is in focus with something. This AF mode is available in some PIC modes, like Macro mode, I think.
AI Servo AF will not lock the focus, and if the subject or the camera moves, the camera will continue to seek a sharp focus. Servo AF will allow the shutter to fire whether in focus on not. This is mode only available in the Sports PIC mode.
AI Focus starts out in One Shot AF, but if it detects subject movement it switches to AI Servo. It does not switch back to One Shot unless you release the shutter button and start over. This mode is available in P, Tv, Av, M and probably some PIC modes.
The DRebel defaults to the AI Focus in most modes but switches very easily into Servo. Much easier than any other EOS camera I've used. In fact, too easily for most people. For example if the camera locks focus and you them move the focus manually (only on lenses with FTM), or sometimes if you zoom, or even pan the camera; all of these can force the camera to switch to Servo when you don't really want it to. The Wasia (Russian) firmware hack can force the camera to stay in One Shot, but it can't force the camera to start out in Servo.
Don't mix magnifier mode and expanded focus mode.
Magnifier mode is simply a short AF range operating mode, like a kinda super-macro. Whether you selected mag/macro/normal, the camera operates always same except that the focussing range limits are changed accordingly by the S/W. The lens itself is capable of focussing from 1cm to infinity anyway.
Expanded focus is used on some still and video cameras to assit manual focus because the LCD's resolution is lower than the CCD's. It can be seen as a workaround for the lack of optical reflex viewfinder (Sony cams ar not dSLRs, including HDR-FX1!). So the center area of the pic is "digitally zoomed" to make sure you can adjust a sharp focus of the point of interest in your frame. However it has nothing to do with macro shooting, and works at any distance within the lenses focussing range.
Hope having helped
I've played around with the 'unsharp mask' filter in Photoshop CS, and I must tell you the results were amazing. I guess I should have mentioned that I'm very new to digital photography and I'm learning new things every day. I've had my FZ10 for 10 days now, and same goes for PS. By the way, do you know where could I find a good PS tutorial? The PS copy that I have came from my university's software licence department, with no manual. I know it is an amazing piece of software, and I want to learn.
