As many of you have seen on Twitter, I was the lucky recipient of a much-heralded Canon 5D Mark II for Christmas. The reviews of this camera have been righteously positive – with a couple of cautionary tales around some early firmware problems.� Since I’ve been nothing but happy with my 40D since I got it a year ago – I wanted to do a stress test to see if the 5D lives up to the hype.
This is really unscientific.� I’m not using a tripod.� Heck, I even shot the pictures a day apart.� It’s also not fair – the 5D Mk II is about double the cost of the 40D.� But, is it 2x better?
For the test, I set both the 5D Mk II and the 40D to ISO3200.� On the 40D, I had to enable a custom function to get 3200 (shown as ‘H’ on the LCD).� In both shots, I used Canon’s superb 24-105L lens.� Here are my results:

Canon 5D Mk II @ ISO 3200

Canon 40D @ ISO 3200
Exif info:
5D Mk II version: Canon 24-105mm @ 105mm, ISO 3200, f/4.0, 1/80 sec
40D version: Canon 24-105mm @ 58mm, ISO3200, f/4.0, 1/125 sec
Clicking on either picture will open up the original (note: careful, they are BIG – especially the 21.1 megapixel 5D image!).
My impressions?� Wow, is 3200 good on the 5D Mark II.� I’d totally use that shot.� It’s clearly better than the image taken with the 40D.� The 40D image shows a lot of noise in the red portion above the Christmas balls.� The balls themselves look ‘crispy’, as does the ironwork on the 40D shot.� I gotta say though – the 40D shot looks way better than I would have guessed.
I also printed each @ 4×6 with my Canon i9900.� The shot from the 5D Mk. II is noise free and looks great – very vibrant and lifelike.� The shot from the 40D looks very noisy, even in print.
Conclusion?� At least in terms of low light performance – the 5D delivers.� I’ll be looking forward to finding out what else it can do.
