Feather detail with a beta 7D

Here's sharing a bird photo from a pre-production 7D I tried recently.

Yellow-vented Bulbul (Pycnonotus goiavier)
Canon 7D (pre-prod.) + 400 2.8 L IS, f/2.8, ISO 200, 1/200 sec, manual exposure in available light, tripod/gimbal head, cropped to 2400x1600, then processed and resized to 1200x800:

Very nice shot.

Awesome shot, great looking image.

I'm extremely unimpressed by this image given the lens and cropping. I'd be surprised if and XSi couldn't keep up given the same equipment.

I respect your opinion.

At f2.8???? Okay, that's it. I want mine NOW.

From what I understand, the XSi is an excellent camera. I liked my XTi.

Hi Romy, thanks for sharing.
I think the level of detail is impressive in both this and the bee-eater shots. They look great!

However, what is your honest opinion of the 7D's abilities at ISO 400-800.

On your shots at these ISOs I'm seeing the same 'white noise' that is present on all of RG's sample images - the omnipresent little white specs that appear be a noise-reduction artifact.


They seem to be gone in your processed images.
How do they affect post-processing.
Are they something to be worried about?

Also, what is your overall impression with camera.

Thanks
George

Hi George,

I'm pasting here (in italics) my comments posted in another forum:

Based on capturing and processing in DPP many RAWs with a beta 7D, here are my impressions on the camera's noise characteristics. Note that this is a result of my subjective "visual feel," and not based on objective scientific testing or numbers.

1. ISO 100 is very clean and can take aggressive sharpening before noise starts to be noticeable in the shadows.

2. ISO 200 - 400 are not as clean when compared pixel-to-pixel as those of the 5D2, 40D, 1D2 and 20D. Noise (albeit very fine grained) starts to be noticeable in the shadows with aggressive sharpening.

3. ISO 3200 - 6400 have fine grained noise, but none of the banding I see in the 5D2. Even ISO 12800 has no or very little banding, but the noise grains seem to be larger, and as such this ISO is perhaps only useable for smaller prints or for greatly resized web photos.

4. I'm under the impression that the 7D's noise charateristics are optimized for print rather than pixel-peeping at 100%. I welcome this approach, as we can easily filter out the noise when posting web-sized photos. I haven't printed 7D photos yet, but when I compare these to my previous photos which were printed large, the 7D's fine-grained noise should do well in printing.

Setting aside AF performance (which I wasn't able to test extensively because of severe rains in our islands), and noting my comments above on the noise characterisitics, the 7D is a solid performer in all other areas as specced.

Thanks. Very informative.

You are threatening to cause serious damage to my bank balance

wow color and contrast look awesome! The minor noise doesn't bother me at all.

Lets face it, the 7D is going to be an all round great camera, and certainly very tempting for many being a 1.6 crop at 18 MP it just gives you so many more options to play with images over any other body they made so far.
They have no choice now with the Nikon bodies available to make sure they introduce a spot on body for a much cheaper cost, and that they are
