These are at 2000 euros. I can cool my current camera for only $500AUD or go totally mono for $1500AUD. So don't see it as a option with my budget. Also, I have not seen enough images from the A7s in any case.

This is what I was thinking but to cool my OSC DSLR at the moment as a stop gap.

Agree Paul - but time and money always an issue.

I probably wouldn't going to all the trouble of cooling your 400D, I would spend the money on a newer camera that (uncooled) would almost be as good as a cooled 400D and save a lot of fuss.

If you were keen to go mono though, the 400D would be a good choice, but I don't think it worth the extra money to cool it. The extra sensitivity would somewhat negate the need for cooling anyway.

The 400D is quite noisy, and my best images have been taken when the sensor has been below 10 degrees. So I actually suspect cooling will really help here. Perhaps not as much with a newer Canon such as the 7D, but remember all I am talking about is a $500 investment.

Also - not fussed about having a full frame sensor. The current image size with my f/5 scope and coma corrector works well.

...mmmm...decision time!
