What power are your Ni-MH batteries rated at. It should be printed on them. I would suggest that you should use 2500mAh or higher rated batteries.
Sprocketdog23, they are 1.2V. I was told that would be the right power for my camera. Thanks for the reply.
There was some interesting investigation about this on RiceHigh's site including some videos about it. See link and more recently link
The videos do show how to get round this and that your batteries may not be to blame at all. Still worth checking them though with a multimeter as suggested.

I was lucky enough to pick up A 28/2.8 in a bargain camera bundle lot off eBay that got looked over by everyone else so that's why I'm not too desperate for an FA (and I've had an M version since the ME/MX days.) Maybe it'll happen again with an FA. I can't understand why there isn't a DA version, equivalent to the 35/2.4 that everyone seemed to be lapping up off Amazon before Christmas (me included!)

As John commented above, the colour balance looks very odd. I see from the EXIF data you have the camera's white balance set to manual. That means you would need to reset it yourself for each scene. Normally it is best to leave it on auto unless the scene warrants something different. Even then if it isn't quite right you can always rebalance it afterwards in your Elements 7. Auto normally sorts it out OK.
Also you have Contrast, Saturation and Sharpness each set to high (2). I'd experiment to see if you really need those set so high. (I used to find that I did need to do that on my old EOS300D too, but the K100D I replaced it with was just fine with normal settings.)

Not only are the subjects nicely taken they're all well exposed and lovely and sharp. Well done.

When I got my 150-500mm from SRS it was something of a bargain compared to all the other mounts they sold and what was on eBay. However I cannot see it listed presently, wonder why.

As said above, the AF is looking for contrast differences to lock onto and found them somewhere between the bright window and dull interior. It does it mathematically, not aesthetically!
Sometimes I found that when shooting a landscape with a branch in the foreground, the AF would lock onto the branch and not the landscape!
I have gone a step further now and moved he autofocus function to the AF button at the back to prevent the focus going out of focus as you press the shutter. Then there are some scenes that just have to be focused manually, but the centre focus method usually overcomes the need to do this.
You probably wouldn't notice this effect with a point and shoot camera with a small sensor as they have an inherent greater depth of field. But a DSLR gives you more control which is needed when the depth of field of a 50mm lens at f4 is not very wide.
