Taking any picture with depth to it at f1.4 will be disappointing, especially one like this example where you would have to really search for the sharp plane of focus.

Try a flat subject and focus very, very carefully....

I presume you've made sure the site is logged with Google and others? And I suppose if you get involved all over the various forums that would help as well.

But for a focused approach why not try one of the library sites like FotoLibra? That's where people look who want to buy images.

The limit switch will stop the lens hunting all the way out to infinity and back when doing close up work.

We haven't noticed the problem yet on the *istDS or the K10D. The pixel mapping of the K20D should solve any problem, but that's for the next upgrade.

A few stuck pixels should be quite easy to clone out. Not ideal, but eventually it may be inevitable.

HDR enables images with a very wide dynamic range to be reproduced within the capabilities of curent materials without losing detail in shadows or highlights.

This gives a very distinctive look to the images and when done well can give amazing results.

Personally I'm not sure I like the effect when it is used for every image and I would prefer to save its use for those images that suit the technique. In a similar way we wouldn't sepia tone every image.

It's worth looking in to and when used with a suitable image can be fantastic.

The subject has been covered on the forum many times with some people getting on well with generic batteries and others wanting to stick with the Pentax original.

Just be aware that some of the very cheap batteries can be cheap and dangerous fakes and liable to overheat or catch fire. This would certainly invalidate your warramty. The US have issued warnings about cheap LiIon batteries in relation to air travel.

Although I now use three batteries, normally two will be sufficient.

Fully charge both to start off with and use one until it is exhausted. Then change batteries and be sure to charge the exhausted one when you return home. Keep rotating them in this way and you should have no problem. They retain their charge very well.

If several weeks have elapsed or before a major trip I would recharge both batteries again as a precaution.

Amazon is offering the pentax battery at £32.95, which is somewhat better than the SRP of £49.99

Martin Evenong's book is the one I would recommend.
