They do ship outside the UK, just not from their web site.


Just ring them to place an other.

The bads of 1.2V batteries

As far as I remember... Alkaline 1.5 volt batteries have a high internal resistance. So when you actually try to draw a large current they voltage drops to about 1.3 volts. Since rechargables have a very low internal resistance, they stay at 1.3 volts.

Thus a 1.5 alkaline == a 1.3 rechargeable in actual use.

Not sure about disposable lithium batteries.

Some things I've noted. If I take a lot of pictures in a hurry, the battery "goes dead" then after a minute or two, shows up as fine. I think this may be due to the internal chemistry of the batteries, but I'm out of my depth here. Anyone care to comment.

Also some have said Focusing is better with Lithiums and with fresh rechargeables.

Flash how to question.

Why do you not want to use the on board flash. Just so that it does not light up the subject ?

If this is what you want... you can go into the menus on the k200d and set the flash as a controller rather than a master.

It will pre-flash, to trigger your off camera flash, but it will not fire for the actual picture.

You get wireless flash, w/o the on camera flash contributing to the picture.

Does that help ?

From Amazon.co.uk.

2 of SanDisk SecureDigital Ultra II Card SDHC 4 GB @ £10.99 each

Item Subtotal: £21.98
Shipping & Handling: £10.00
Total: £31.98

They came with a free SDHC reader.

They work just fine in my k200d.

At that price, why buy less than 4GB.
