I'm not sure what you mean by that. When you exposure lock the shutter speed at about 1/2 second, and the aperture is locked, you will see an actual ISO of 51200 (with shutter between 1/40 and 1/50). I measured it. It looked like crap of course.

Also, noise reduction is easy in post.

WOW i have never seen ISO 51200, i have to go try this tonight... That is insanely high!

I guess i should have been more clear that you will not get super high usable ISO out of the camera. You will need to adjust in post. But as always the better out of the camera the better it looks in post! :)

wow 51200... sorry i just wrap my head around that number :)

thanks

Read a bunch of posts starting at around #31 for thread http://www.dvinfo.net/conf/canon-eos...ification.html

Just from looking at the supplied picture....

1. The depth of field is high, which tells me you have the aperture stepped down.
2. The very limited amount of blur in the vehicles going across the frame tells me the shutter speed is quick, especially considering it is night time.

Which leads me to conclude

3. You have the ISO/gain cranked way up.

Just a thought, but have ypu set the meter lock function properly?

#3 implies intent on my part ;)

This problem was solved using faster lenses. The one I tested with was the 24-105L F4... just not fast enough to give a clean picture in low light. The f1.4 was enough... but barely, and had to expose down a bit to get under 2500iso, which to me is the point it starts to get ugly.
