AA Alkaline cells are 1.5V when fully charged. 2700mAh. Carbon zinc are 1100mAh
AA NiMH cells are 1.2V (though fully topped up may be slightly higher). Capacity varies.
AFAIK, the internal resistance of NiMh and NiCad is lower than alkaline - so you can draw larger currents (e.g. for motors etc).

HTH!

From using them in model aircraft applications, NiCads have the lowest resistance of all the above. They are now no longer available due to the cadmium (heavy metal) in them. As Matt says their single cell potential is 1.2V and the only time I could see is when you need the full 1.5V.AA Alkaline cells are 1.5V when fully charged. 2700mAh. Carbon zinc are 1100mAh

I know of applications where the current draw is very small and Nicads are not recommended because their self discharge rate becomes significant - calculators for example.
I would be surprised if you have any problems.

My predictions would be:
That the DA super telephoto = DA* 400 f/5.6
DA*30 f/1.4
TC 1.4 SDM
Besides the 645D no new camera.
a WR flash
Have you any evidence for any of these or are they purely speculation?...

The DA* 400 appeared on another forum and was a very obvious fake.

I can confirm that both 20 and 30 MB/s Sandisk Exrememe III cards normally work in the K-7.
I don't think there's anything left to argue about, guys.

Not the one that other togs are going to nod and make appreciative noises at.
Not necessarily the one that is most technically brilliant and shows you and your kit at your combined best.
More the one which reminds you why you take a picture in the first place.
This is mine from this year -

Lets see the photos that you might not submit to PPG, but you are pleased you took.

I suspect the Extreme III is one of the cards of choice for K7s and if there were a bug in anything that stopped it working, I think we would have heard about it before now.
You are a very prolific poster, but sometimes you are well wide of the mark Stefan.

K10D - is gold jewellery as good an investment as it used to be in the Middle East? When I was in Saudi 10+ years ago, it was sold by the weight of the gold so an ingot cost the same as something beautifully crafted. Mrs Oggy has some really nice things.
L4byr1th - you might try Currys if you just want to hold the camera. The Lion's Farm branch (a few miles West of you) has one in.

Matt - the K20 manual does confirm that the charger supplied with it is suitable for 100-240Vac.
