Anyone who has used SLR cameras for sometime, and is familiar with the basics of photography, this probably is the best DSLR under £1200. If you are prepared to spend some time with this camera, you will realise how much can be done with this kit. The K10D allows full control over every aspect of digital photography, you can tweak it to your preferences, there is multi exposure options too. The image quality is brilliant. The metering system has not let me down, and is more accurate then most DSLR's in the market. The build quality is superb, I can not think of any other DSLR camera with a better build quality under £ 1200. As per lenses are concerned, this camera is more backward compatible than any DSLR. Pentax is also introducing new USM lenses. The present available range is more than enough for any Advanced Enthusiast / Professional. The interesting bit is its backward compatibility, which allows the enthusiast to dig into 25 million lenses that Pentax has made since the early 70's. This is a camera for someone who takes his / her photography seriously, is looking to experiment and is familiar with the basics.
I would recommend this camera to the serious enthusiast without a doubt.
