p.1 #1 · My EOS 7D review published!

I have finally finished my user review of the 7D. It has taken much longer than I originally anticipated due to various factors. Those who have had my previous reviews on the 40D and 50D will know my style of review. I hope it will help those still on the fence.

Nice review, your comparison to the 5D MII was very interesting. I actually did a similar test last night with some portraits and saw the same exact thing. I basically focused on the eye and zoomed in 100% and compared. The 5D MII at 100% looked way sharper then the 7D, but when zoomed out it was barely noticeable. Its always fun to pixel peep, and I find it amusing when people freak out doing that. I have no issues at all with my 7D and plan to use it for most of my wildlife photography...however I am going to stick with the 5D MII for portrait work...then again most of that is because I love the look of FF sensor.

Wow - that must have been a lot of work? Thanks for taking the time to do that - well written.

I wonder if perhaps the 5D2 samples in the review look noticeably sharper because it's been sized down to 7D resolution?

Well that's the fair way to compare

Cool review. That was a heck of a lot of work!

What I found surprising were the 50D vs 7D comparisons (the 5DII results are expected). That 50D did amazingly well and, to my eyes, were ever so slightly better in your comparisons at all but the 2 highest ISO samples. However, your sample lighting is very forgiving and has few deep shadows or low mids. A typical night scene of mainly lower mids and deep shadows would not have fared so well for the 50D. I think the 50D is less tolerant of underexposure than most EOS.

Nice review and comparisons. It was also interesting to see someone apply real-world PP to the 7D images to see how close they can get them to resemble 5D II images.

I must admit, I thought the same thing. The boards seem to be flooded with people complaining of the 50D's high ISO noise and praising the 7D's high ISO noise. Even with uprezing the 50D images (which would magnify the noise), it certainly seems like much of the criticism of the 50D is rather unwarranted. Which, to me, seems like excuse enough to pick one up when my Rebel goes.

That being said, as far as the 5D2 vs. 7D, I believe the 7D is starting to get limited by lens resolution. Most certainly, the diffraction at F/8 is affecting the sharpness of detail, compared to the 5D2. This was one of the main reasons why I switched to a full frame camera

A very extensive review, Roland, thanks for posting!

I have a couple of questions, hope you have time to answer

What NR and sharpening settings did you use in the RAW conversion?

In the comparison vs 5DII, ISO 100, how would you explain that the white on red details in the background of the crops look sharper for the 7D than the 5DII? Or maybe I'm wrong. The details in the red in the background, lower left, looks at least as detailed for the 7D, but more sharpened for the 5DII.

Thanks in advance.

Interesting observation. I'm wondering if it's a DoF issue or maybe a front focus issue.

I'm not questioning the fairness. I was just wondering because I looked at the 7D and the 5D2 in Imaging Resources and the difference is not as obvious as in this review.

I see what you're talking about per my recollection up until ISO 1600 they're pretty close so might be something wrong with this latest review ?.

I don't mean to put down this review, but here are IR test crops of 5DII, 7D and 1DsIII at ISO 100 processed in CaptureOne (The jpeg engine struggles with saturated reds).

There is probably a focus issue with the 5DII test at IR, but as you can see, there is no reason to fear that the 7D can't resolve:

7D
1DsIII

Imaging Resource comparisons are useless imo since it's all noise reduced to hell

I do not know why the 5D Mark II images look sharper, but if I were to guess, I think maybe the 5D Mark II has a significantly weaker anti-aliasing filter than the 7D and that could be the reason why the 5D Mark II images looked sharper

Possibly - but could it simply be because the higher pixel density is outresolving the lenses?

Nice job on that review! I would be curious to see the 7d shots with contrast adjusted to match the 5d2, I wonder if it would make them appear sharper.
