Thanx for the offer, Justin.
Tonite I'll be hopefully shooting some brick walls with a demo 7D and will let you know what I think of it.


Best of luck (and enjoy)!

Brick walls sounds like a lot of fun

I'm actually really interested in your results...it looks as though the ebay cashback is closing and I need to make a decision asap.

Here is a shot from my 7D and 100-400 at 1600 ISO. This was shot raw and converted in Lightroom 3.2 beta with no adjustments at all. Everything is at Lightroom defaults. First I include the full frame, resized to 25%, then a version cropped and resized to 50% and finally a version cropped and shown at 100%.

Peter, for grins you may want to view this old thread: https://www.fredmiranda.com/forum/topic/821682/

This was posted tongue-in-cheek at a time when several other active threads (from Photogdave and others) were claiming that the camera could not focus. These are just snapshots but it shows that a good copy of the 7D paired with good lenses can render nicely focused images at 100% (within the limits of handheld shots wide open).

WRT to sharpness all the comments about good glass apply. Also, the diffaction-limited aperture of this sensor is roughly f6.3 or so... (it's equivalent to about 45Mp on full frame). In practice

Thank you, Gary, I must have missed the thread on "colour blur" filter.
Also, the only NR tool I use is "Neat Image".

Tim, those crops tell quite a story. Excellent !
Just to make sure I understand........no NR was applied to that image ?

Also, would you happen to have a similar example done at ISO 100 or 200 ?

Lightroom has some Chroma NR applied by default, but Luminance NR was left at zero. There may be some invisible NR behind the scenes that Lightroom does not disclose, but those images were all prepared on default settings.

Peter i don´t own one but i see thousands of images through the net every day since a lot of years.The files of the 7d do not have the crispness, silkyness, the smoothness and sharpness of other cameras files(like 1d mark iii for example). this 3d feel i see on the mark iii files it´s not present in the 7d files, in fact the most sharp images i saw are the ones of Zenon Char. Everyone wants to make wow!!! while seeing your samples
and i think you won´t reach what you want with this camera.
hope this will help you

Here are similar crops from a 200 ISO example. Once again, no edits of any kind....

That's good enough to my eye, I see no ISO noise problem of any sort.
Good detail retention, very tightly packed fine, almost monochrome grain can be seen on the largest crop which doesn't impinge on the image detail.
Thanx.

LR3 makes the 7D worshipable

There's no doubt the choice of software for conversion can make a considerable difference to the look of a file. Here is a 100% crop of the robin, but processed in DPP. I have not tried to match the look of the file from Lightroom, but simply applied typical default settings that I might use in DPP for a 7D file.

For this example I have reduced luminance NR to 0 and left chroma NR at the default value of 4.

Perhaps 7D is a tool I might use to explore low light BIF in conjunction with f/2.8 and faster lenses ?
Unfortunately, 1DMkIIN ISO 3200 is horrifying even after NR application.....see an example bellow.

Did you see any of my BIF examples with the 7D at 3200 ISO? Here's one with NR and sharpening at defaults....

Tim,
Your pictures make me want to run out and buy a 7D. Oh, wait. I have one

Great set and good discussion. Now I just have to work on my BIF skills to get up to your ability to make the 7D sing. Well done.

Tim, those are all excellent shots that really show the capability of the 7D as do Zenon Char's shots. Very nice job guys!

It's awesome, and the people tat don't like them are just whining.

+1 on this comment. I've never seen so much unjustified whining about an electronic device.

My only (minor) complaint about my 7D is the noise level. At ISO 400 it is higher than I expected, but as others have pointed out, it can be dealt with easily using any of a variety of programs or NR plugins.

for 7D shooters .... look into LR3beta2.

It is funny how shooters get all bent out of shape on noise.
do we remember the film days?

Get the camera or get something else - 1DmkIII/1DmkII ... just get out and shoot!

Skill is still the trump card in all of this.

If you don't mind me asking a silly question, how is it you use LR3 to get the most out of the 7D files? Do the files just look better when converting from RAW, or are you using a noise removal feature within Lightroom?
