Thanks for that. The images you posted are in JPG format, is this was the Canon 500D outputs its RAW images as? (i.e. lossless JPG)

Thanks to you too Merlin. Very useful info for me.


I think I may have narrowed it down now to the following, unless someone wants to throw something else into the mix?
  • 550D (same as the 500D but newer model)
  • 1000D (cheaper but still very popular)

The Pentax Kx is still in my sights given they are apparently quite good in lower light situations. I did however read that they have an automatic dark frame after 30" exposures which you can't turn off.

Thanks,
Af.
