akclimber,

buy a 1D mark III - People will be dumping them to pay for the ultra expensive 1D Mark IV
The 1D III may have less noise then the 7D due to much fewer pixels and a larger sensor
But then you might have 1D mark IV envy

I am finding the 7D to be reasonable for noise levels. The noise cleans up well.
I find that shooting birds at high ISO rarely pays off. In such poor light the images often suffer just due to the quality of light, not the noise level.

I prefer the 1.6 for crop-ability with a 400mm F5.6. If you cannot afford the 500, 600, 800 telephotos the 1.6 sensor in the 7D makes sense. I also like the lighter weight and size compared to a 1D.

but to each their own ....

Thanks for the suggestion but nope - not enough MPs (looking for at least 16 MPs - I'm printing large prints) and I want AF I can reasonably rely on (and yes, before anybody wants to get into an argument about the 1D3 AF, I personally - not just thru the net - know pros and non-pros who have had very inconsistent results with the AF on their 1D3s). Frankly, I'm in the "keep dreaming" "Canon has to eventually produce a 3D" camp. Maybe this winter or next fall, who knows.

akclimber,

makes sense to me. I passed up a good deal on a 1D Mark III for the same reasons
I like the 7D

maybe buy a used 1D mark IV in the future

Here is a shot with my 7D, ISO 3200, 500 f/4.5 (non-IS), effective focal length of 800mm, 1/160th second handheld while floating in a kayak. Some NR applied. You be the judge.

David Israel,

Nice shot David

I too have been happy with 7D noise performance. But have only used the 7D a few times. I am still learning to process images.

what are you using for noise reduction on high ISO shots?

What do you set the 7D to track? I have tried different things but as soon as it gets away from the original focus point the camera focusses on a new object. It isn't switching focus points to track.

I think if you're on AF point auto-selection, and you switch to AI Servo AF, the center point lights up and you acquire focus with it, but then it tracks and switches points to follow the subject. You may have selected one point AF, that's why it doesn't change them.

Thanks!

I use both Noiseware Pro and Noise Ninja (depending on the particular job).

The GBH was taken after the sun had already set below the horizon, but there was still some evening light available (just not a lot).

While the 7D isn't quite in the same league as my 5D Mk2 or 1D3 for low light performance, it has impressed me so far. I am really liking this camera body.

Great shot, David!
Thanks for sharing.

Have you used your 7D with the 800?
Must give some nice reach... to say the least!

I too am enjoying my new 7d.
A definite step up from the 50d, which I really was never very fond of.

I also agree, not in the same league as the 1DMIII, but still very good.

Now, how about that new 1DMIV...

I wonder how many of the people who are having noise problems, have cameras with gain calibration issues of the sort skibum had. The issue his camera exhibited, when less severe, would simply show up as a somewhat noisier RAW conversion.

Is there a simple way for people to evaluate or check to see if they have this problem?

Kiran, that's some sweet light! Gotta love the yellow/blue complementary color thing. The reflection really adds a nice touch as well.

Cheers!

The first test gives a wealth of visual information, as you see the difference of neighboring columns and how badly out of balance they are. The second test is a quick test to see whether on average the two green subarrays are differently calibrated.

Fred has done a big update to the review section, and the 7D is now in the review section.

A few from a football game tonight. ISO 12,800 and cleaned up using Dfine. 300L F4 IS @F4, Shutter speeds averaged at 1/320. Ai servo using center focus point. Oh yes. High speed continuos.

Nice going, David! Looks like you're getting great use out of your "yak" and 500/4.5!

That looks super-clean for ISO 3200. Do you happen to have a version of this prior to NR you can share?

Thanks,

Jim

Wow. Those are incredible images at ISO 12,800. Well done!

The lack of pattern noise in the 7D brings a new meaning to post-processing and opportunities to really push ISO in low-light conditions.

No, no! There must be some mistake - only the D3 and D700 can do this. I read it on an internet, so it must be true!

Here are a couple of short videos I've made with the 7D and the new 100mm F2.8L macro:

1876 Trade Dollar

Water Drops in Low Light

I love this camera/lens combination!
