Thanks. Apparently the ability to shoot at such high ISO without concern for excessive noise is going to yield lots more options in selecting subjects and lighting situations.


Yes...between that and the IS on my 17-85mm lens, a whole new world of opportunity has opened up for me..now if I can just get smart enough to take advantage of that..I`m in business !

Your shots look great to me. I see some minor noise in the full sized crops but not as much as some cameras I've used at their lowest setting. But, at the risk of sounding picky, I could make better judgements on the 20D's noise level, if I knew aperture and shutter speed as well as ISO. But I'd venture to say that Canon's claims for the reduced noise levels will hold up and that the 20D sets a new standard in it's price range. Thanks for sharing.


The info you requested Harvey is...
Shutter speed...1/320
Aperture...F4.5

:-) Was just looking through the logs of the site, wondered why someone was linking to a picture on the site... At least the hotlinking stuff works!

I've shot with the 10D at ISO 1600 with little or no noise. It all depends on the subject.

Hope nobody thinks I`m trying to imply that the 20D beats all the competition here.
I have absolutely no experience with DSLRs and am experimenting to find out what works and what doesn`t, I`ve posted here for an evaluation from people who can compare.
My own view is that it produces much better images than I was prepared for at such a high ISO setting and under conditions (floodlighting)where I expected a to see a lot of noise.


This was no indication that you were. I was just making a statement based on experience with my camera.

okay, so judging by the photos there's obvious a light source so it wasn't completely dark or anything. Maybe it's a matter of there being enough light that the sensor didn't have to compensate hugely, therefore, not tons of noise.
Just a thought.

I shot photos with my 10D last week at ISO800. When the sun hit just right there was wayyyyy less noise, but when it went behind a cloud the noise was terrible.


That's because noise is mostly dependent on shutter speed - less light, longer shutter speed, for the same exposure...

Thanks

Can't seem to get any error messages up.

It's setup so that if you link to an images path name you will get the stolen message i.e. //www.brownt.co.uk/images/t.jpg

Thought you might like to know - went to your site and every image comes up as 'image stolen from //www.brownt.co.uk


Site looks fine to me... Is anyone else having problems??
Use this link, //www.brownt.co.uk


Just getting the "Stolen" message Terry instead of the displayed image.
Meant to mention that to you the last time I visited..but thought it might be something wrong with my setup.


Which links is it that you are clicking on?

You guys are trying to make me upgrade to the 20d aren't you?

Not a thing...the 640x640 crops are from the original image.
The processed images were adjusted for contrast and sharpened but nothing else

No

wow,, that is 100 times better than the 10d @ 1600! thx for posting

Here's my estimation on lens affecting noise:

All the lens does is directs light onto the sensor. On a cheap lens this is done badly, on an expensive lens this is done well (with relation to sharpness and distortion). However the light is directed it still hits the sensor in an essentially uniform manner. Hence, L glass does not reduce noise.

Edit: Corrected typo.
