I would go for a K-5, K-5 II or K-5 IIs if at all possible. You will find it an amazing step up from your K10D.

Prices at the moment are quite low and it should last you for quite a few years yet.

It doesn't seem to be as waterproof as the standard WG cameras. These are good for 14m and 2 hours.

Would it be ideal for snorkling in the Red Sea for example?

The images would be dreadful Nigel. Dark Frame Subtraction is a very clever idea that works brilliantly, so I certainly wouldn't want to turn it off.

Tremendous photography, I'll post a link or two to your site elsewhere as I know some people who will really enjoy your images.

I've never got totally to the core of this, but I have assumed that the aperture is indeed the one you have set and the aperture value is the wide open aperture of the lens at that zoom point.

The MX with 40mm lens is a lovely combination. I've had several over the years and they have all given good service.

That one doesn't appeal to me at all for general use, but it could be that it's just the thing to use underwater.

I've moved this to lenses as it seemed more appropriate.

I don't think Jessops will be pro- or anti- anything, as long as they have the best margin they can get. Sometimes companies might offer incentives of one sort or another to stock their items.

As far as the Manchester store goes, last time I looked they had a reasonable Pentax selection. Most if not all of the bodies, plus quite a few lenses.

If you want Pentax though, SRS especially and a few others are the ones of choice.

Please see the competition itself, we await our judge who is now aware of what needs to be done.

I like them all, they have a really good feel for the subject matter.
