Canon EOS 7D vs. Canon EOS 5D Mark II: Low Light ISO Comparison
Previously we took a look at how the Canon EOS 7D fared against the EOS 5D Mark II in a series of ISO comparisons taken in largely average lighting conditions. In this edition, let’s take a look at how the EOS 7D does when the lights are turned off.
For this test we photographed a scene at roughly 8:00 PM, which works out to about near total darkness where we’re located. In the example shot below, the scene is only being lit by the light above the door, and somewhat by lights behind the courthouse building. For the shots, I set the camera to f/11 and then came up with the following shutter times: 15s @ ISO 1600, 8s @ ISO 3200, 4s @ ISO 6400, and finally 2s @ ISO 12,800. White balance was set to auto, picture style was set to standard, noise reduction was disabled in all of its forms (long exposure and high ISO), and for this shot I also disabled auto lighting optimizer. Each shot was then taken into Canon’s Digital Photo Professional, and kicked out with zero noise reduction.

Thanks for the comparisons here, i liked them very much.
But i look like the 7D images looks sharper then the 5DmkII.
Or is it just me?
Marcel,
Your welcome, and I think they may be just a tad sharper…
This is a late reply but I must,
The 5D MK 2 has a shallower depth of field in these tests due to the crops being equalized in size. Don’t confuse that with sharpness. Look at the photos foreground only in comparing sharpness. Also noise can create the illusion of sharpness due to the grainy look and the 7D is alot noisier most of the time.
The truth is, 5D MK2 is alot sharper and a proper sharpness test will show that. I bought a 7D, was disgusted with the image quality, sold it and upgraded to a 5D Mk2 soon after. If u don’t care so much about image quality and FOV issues then the 7D is a winner in every other respect.
The image quality on the 7D was less sharper than my entry level 1000D. I was disgusted. I ran test after test to try and prove otherwise. I later found out that the 7D has a low pass filter infront of the image sensor to soften noise. It softens the images as a result. This I don’t like!!!!!
Jason,
As you pointed out, this isn’t a sharpness test, just a low light test, and no question in my mind that the 5D2 is sharper than the 7D.
5d mark ii with 17-40L f4.0 vs 7d with 16-35 L f2.8….for lowlight photo
Excellent test, thank you.
Finally a test that tells the story of low light performance differences in the true sense. None of the usual elementary tests done at other sites.
In summary, I see GREAT 7D performance so kudos to Canon. However, the 5D mark II is at least a half stop better at 1600 ISO and clearly ahead with 1-2 stop advantage above that.
Chuck,
hey thanks for compliment. I think the 7D is doing a fine job too, I had expected worse given the bump in megapixels, but I suppose sensor improvements and dual digics are doing their job. On the other hand, I’m happy to see my 5D2 doing fine over a year into its product cycle!
Thanks for the info. I am a semi-pro photographer and I currently use a Canon XTI and I need to up grade. In you opinion is a jump to a 7D enough or should I look at the 5D. Is the extra cash worth it or do you have another suggestion?
Really depends on just how important image quality matters in your work. If it is the main aspect–the 5D2 is your camera, in nearly all other aspect the 7D is definitely worth it. I’m an I.Q. freak—it’s all I really care about so that’s why I love the 5D2, but in many ways the EOS 7D is a superior camera.
I was in the same boat and I was interested in very nice all around lens also I wanted to buy nice printer (pro 9000 mark ii). I had 2 choices. 7d + 17-55mm (f2.8) or 5dii + 24-105mm. 7d+lens package was costing approx 2700 and
5d kit was available for 3500 ($400 rebate for printer). Considering printer rebate, the difference between both system was 400 (12%) so picking up 5dii was no brainer.
in the pictures I se that 5d has better quality, how you thing that 7d is better?
Besim,
Maybe you misunderstood, I don’t think the EOS 7D is better than the EOS 5D II, when it comes to image quality and ISO performance, the 5D2 is clearly superior.
If I bring D700 into picture, which one will you go with?
gurbally,
I love the D700, if I did sports or more dynamic subjects, I’d probably have one. Since I do more landscape, street, still life type work, I prefer the 5D2’s resolution.
Are the samples in RAW format, or it’s JPEG?
Looks like jpeg. I think 7D has more aggressive post image processing. 7D’s shots looks over-sharped, whilst Marks shot are quite soft. IMHO, additional noise on the 7D shots is nothing but jpeg artefacts caused by sharpening. My guess is rest upon evident blotchy artefacts tipical for jpeg compression.
Does anyone agree with me?
p.s. sorry for my poor english
h1,
the samples are from RAWs, but of course converted for the web to JPEG. Both were set to 0 sharpening in-camera, though that doesn’t mean one is equivalent to another. The additional noise on the 7D files is additional noise, it’s noisier for sure than the 5D2 which even though it is softer, still provides more detail–.
The fact that the EOS 7D fares so well in comparison is remarkable, considering that the EOS 5D Mark II has pixels that are 2.240654 times as large.
It does a good job for sure, which one could also expect from the T2i I would assume. I wish they’d go with bigger pixels by having less megapixels, but at least their NR tricks in-camera keep it competitive.
I’m wanting to upgrade my 40d, I do high school sports photography, night football games and such. Between the 7d and the 5dmII which would be a better choice. I’m looking for higher quality of shots when blown up to small poster size. Lighting is a problem with the football games, shooting fast enough to freeze the picture…I shoot with a
The 7D is much better suited for capturing sports, and the prints are pretty close in size. The issue I see is “night” games. I don’t know what kind of ISO you’d be shooting at, but I suspect ISO 3200 and higher-based on my experiences. I really didn’t want to push the 7D to ISO 3200 and 6400 too often for sports, as the noise takes away from some of your sharpness. If your lens is f/2.8 and you want shutters over 1/1000 you’ll see what I mean, you know you should put the camera at ISO 3200 or 6400, but you won’t want to because of ISO. So the 5D gives better low light, more than stop worth, but slower fps and a less agile AF, meaning likely less keepers than the 7D. So I guess I’d say the 7D. Though the real solution is probably the D700 and battery grip (or D700 replacement when it comes).
I’m trying to weigh up the 7d vs 5d mk2…i use one camera for everything…landscapes, portraits, low light band performaces without flash, and capturing big indian weddings where a lot of dancing goes on in very dim conditions so need a quick shutter speed and high iso. Just to confuse the matter, initially i was favouring the 5dm2 as its priced attractively when bundled with 24-105L lens, compared to if i bought the 7d body only and seperate 24-105L lens (i like this lens a lot)…but now the 550d has come out and it seems the high iso performance is practically the same as the 7d, but its half the price…so now i’m wondering…550d plus nice lens, plus money left over, or 5d mk2 bundle for quite a lot more money…would be good to hear your thoughts on that one…is the full frame advantage only on iso side of things…or is the image quality/colour rendering still “nicer” compared to 7d (just wondering if that gap has also been closed with the release of these new models)
Thanks,
Sanj
I don’t think that the 550d will be the best option given your scenarios, the 7D would be better with focusing and overall build, but the 5D2 does much better in my opinion in overall IQ and noise management than the 7D. Many, many wedding photographers happily use the 5D Mark II, though a good many, maybe more use the Nikon D700 as well– just to throw a wrench in your plans. But yes the 5D2 is “nicer” than the 7D– I like the 7D a lot, but it has’t made me want to turn in our 5D2 yet. (actually nothing has yet, maybe soon).
which one better for low light photo. 5d mark ii with 17-40 f4.0 vs 7d with16-35 f2.8
I’d say 5D Mark II by a mile. But an odd lens for low light work I’m thinking.
The 5DM2 in my opinion produces the best file from a Canon camera, but for the money a 7D is a great deal. More FPS, better AF, but you have to live with the 1.6 crop.
Hi Patrick,
Currently I have a 50D using various L Lens. I’m not happy with the IQ. For a second camera I considering the Mark II. As a novice, I assume that the trade off from the 50D and 7D is not worth buying another 1.6 crop such as the 7D if IQ is most important. I will use the 1.6 crop for some landscape to enjoy the extra Focal length and speed that the 6fps offer. I can’t see that an extra 2 fps would prove reason to buy the second 1.6 crop such as the 7D. Given this, If I have both the 50D and Mark II will the best of both provide everything you find superior in the 7D? Also, I only have one lens that is not L series. The 50 mm f/1.4. With a Mark II will I notice much difference between this Lens and the 50mm f/1.2 L to warrant the additional 1000+ to upgrade? Thanks for your thoughts, Mike
Mike,
I’m going to say no, the f/1.2 isn’t worth it for $1000 if you don’t have $1000 to burn. That’s just my opinion, but $1000 can make bigger differences elsewhere, like saving up for the 85mm, etc…
Dev,
A wise decision. I loved the 7D, in many ways superior to the 5D2. Except IQ, which is what the 5D2 is all about. Sounds like a good deal too…
