Resolution Chart Comparison (JPEG and Raw)

Images on this page are of our standard resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera we use the relevant prime lens (the same one we use for all the other tests in a particular review). The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation set to deliver approximately 80% luminance in the white areas.

What we want to show here is how well the camera is able to resolve the detail in our standard test chart compared to the theoretical maximum resolution of the sensor, which for the charts we shoot is easy to work out - it's simply the number of vertical pixels (the chart shows the number of single lines per picture height, the theoretical limit is 1 line per pixel). Beyond this limit (which when talking about line pairs is usually referred to as the Nyquist frequency) the sensor cannot faithfully record image detail and aliasing occurs.

This limit is rarely attained, because the majority of sensors are fitted with anti-aliasing filters. Anti-aliasing filters are designed to reduce unpleasant moiré effects, but in doing so, they also reduce resolution (the relative strength and quality of these filters varies from camera to camera). In theory though, a sensor without an AA filter, when coupled with a 'perfect' lens, will deliver resolution equal to its Nyquist limit. Therefore, even though it may be effectively unattainable with normal equipment in normal shooting situations, an understanding of a sensor's theoretical limit provides a useful benchmark for best possible performance. Nyquist is indicated in these crops with a red line.

On this page we're looking at both JPEG and Raw resolution. For a (more) level playing field we convert the latter using Adobe Camera Raw. Because Adobe Camera Raw applies different levels of sharpening to different cameras (this confirmed) we use the following workflow for these conversions:

  • Load Raw file into Adobe Camera Raw (Auto mode disabled)
  • Set Sharpness to 0 (all other settings default)
  • Open file to Photoshop
  • Apply a Unsharp mask tuned to the camera, here 180%, Radius 0.4, Threshold 0
  • Make 100% crops and save the original file at JPEG quality 11 for download

The resolution chart shows off just how ineffective the JPEG engine is at rendering fine detail. The 6D comfortably renders detail up to around 2600 lph (which is what you'd expect), but the JPEG gives up very soon after this point, whereas Raw processing and fine-radius sharpening allows you to realize convincing detail beyond 2800 lph Moiré and false color creep in beyond this point, but this is necessary to reach the 2800+ lph that the Nikon D600's 24MP sensor can produce.

For the skeptics and the nitpickers on the 6ds' video capabilities, check that video out. By far one of the best wedding videos i've come across. Most of the couple moments were taken with the Canon 85mm F1.2 ($2k lense) and the chapel moments were taken with the 70d(2:29-2:42). But the dancing with father and bride&groom moments near the stream was filmed with the 6D.

Then this wedding video was entirely filmed with the 6D: https://www.youtube.com/watch?v=j1GG9rUAYvA

I used to own a Canon EOS 50D and I shot great photos with that as well as the first DSLR I had the Canon EOS 10D. It isn't the camera that does the work getting great photos, but rather the photographer him/herself. Now that I own the Canon EOS 6D I am quite impressed by the improvement of the picture quality.

I own this camera and am very happy with it. Being a mostly still photographer I also do video but with a video camera. About the only thing I can complain about here is the lack of focal point for the Automatic Focus. Otherwise it is a great camera that takes great photos. The 6D is not a good sports camera. But for portraits and outdoor photography it is a decided winner in my book.

I am very happy with the Canon EOS 6D camera. I purchased the kit with the 24-105 mm f4L IS USM lens. The quality and fit is exemplary of the 6D. It is more than a Pro-sumer camera. I will keep using this camera until I can replace it with the Canon 5D MkIV.

I have a 5Dmk2 and i want to change my camera for a Canon 6d. I want to ask you, if it worth for wedding photography. It is just for photos, movies are occasionally. I know it is better on ISO and focus on the center AF point on low light, and it is what i want.

It worh to make the exchange ?

I am going to tell you that I have shot weddings with a Canon 50D successfully. Is the 6D up to the task. I certainly think so. I recently upgraded to the Canon 6D and I can say it is quite worth the moderate expense to move forward with the Canon 6D. The only limitation would be the 11 point AF system. But hey, you need to ensure that everything you want is in focus in the first place. Good shooting!

Ive been taking photographs for 45 years and work in cinematography. Personally I think digital has surpassed film for color photography but NOT for black & white photography where film grain adds to the medium.
I bought a Canon 6d because Im invested in Canon and have been since 1972 (although I also have Olympus Pen cameras) I didnt want to pay the cost of the 5d MKIII for amateur use but wanted full-frame the 6d was it.
The pictures consistantly impress me from this camera far outstrip my 7d in IQ and the only weakness is limited focus points otherwise as a travel & landscape camera it hits the mark perfectly.

Just rented the 5d MkIII, 6d and Sony A7r. The 6d had better low light performance, slightly sharper than the 5d MkIII and better controls and autofocusing than the A7r. I've also owned the Nikon D600. I'm so impressed with the 6D that I'm going to get one this week, it's bang-for-the-buck rating hits the mark for me. Well, at least until the 5d MkIV.... ;)

Okay, someone explain. Don't compare the 6D to its peers, compare it to a camera 2, 5, 10, 50 years ago when people were creating beautiful images. The ratings annoy me because they're based on current technology and not historical technology. They're not even based on picture quality. You're nitpicking, pixel counting. Except for a lab analyst, your reviews are totally useless.

Since they're totally different mediums, wouldn't that be comparable to the apples/oranges thing? I think in some ways it would be, and in others, no. Again, the beauty of a photo is always subjective; I probably lost a contest because of the judges, who knows? Some contests I didn't bother to enter back then, 'cuz you had to use Kodak film, and I saved a lot of money by buying Fujifilm at Sam's Club; A LOT of money! But, I'm getting off the subject here - this is a truly remarkable camera for the price. I've used one for a weekend, and can't wait to own one!

welll.. a camera is a box that captures light. Comparing the cameras is all well and good, but the thing that captures the light is the film.. or sensor.. or glass negative.. or whatever the "film" medium is. The glass-which lets the light in is comparable today to anything you used in the past- superior even.. so the question is.. are the final prints from your digital sensor as good as the final prints from your film days? Answer to that.. well yes i agree that there are BW mediums that result in fantastic images. Whether you can duplicate that printing process -- and what about that- Traditional enlarger and papers? Inkjet? Laser? == even in the days of film: Ansel Adams classic books.. the first serious books I ever read about photography: The Camera - The Negative - The Print. .. if you are only talking about one of these- the camera, you are leaving a whole lot out of the discussion.

Moiré patterns are visual interference patterns that can occur in high resolution digital cameras. Anti-alias filters are designed to reduce or eliminate moiré patterns, but have been left out of some recent cameras in order to attain the highest possible resolution. I'm not sure whether or not the 6D has such a filter. Dpreview explains moiré patterns at this address...

The BIGGEST WORST thing Canon did with the 6D,
is the omission of a headphone jack.

It's just UNFORGIVABLE.

Anyone who is interested in the 6D,
will end up getting a 6D,
simply because they can't afford (or justify the price of) a 5D3.

So why would you give them a handicapped tool?!

Call me old-fashioned, but I use an SLR to take photographs. The ability to shoot the odd video is merely a useful extra. I can understand the advantage of a headphone socket but it is hardly a deal-breaker for a still photographer.

I use my 6D primarily for video, but I record proper sound with an external recorder and only use the camera recorded sound as back up or for synching.

If that is the worst thing you don't like about the camera - you must really like what it was designed for ;)

Additionally, the 6D uses exactly the same digi video processor as 5D3... so no I considered the 5D3 but couldn't justify the addition $k for no functional value given how I planned to use it.

For my needs, the 6D really fell into a nice little niche. I don't shoot video, so the headphone jack was a non issue. I don't shoot sports, so the AF system wasn't a big deal.

It saved me a lot of money by omitting features of the 5DIII that weren't of huge (or any) importance to me, personally.

As someone who has shot numerous videos with DSLR's (5D mk2, Mk3) and a canon c100 i personally dont think the headphone jack is that big of a loss. Most of the time anyone really serious about audio for a production will use external recorders and HD processing for audio as the DSLR compresses audio a bit. There have been a handful of times I use the internal audio for the final edit, even with external wireless or boom mics. I prefer separate source, slate it and combine in post. But that's my personal preference after 12 years in the biz.

So, all that to say for the price different between it and the Mk3, I am getting the 6D for my stills and 2nd video camera on set.

This rating of the 6D is weird to say the least. Almost every reviewer out there rated video capabilities of 6D as definitely better then Nikon d610. How on earth here it gets much lower video rating then d610?? Yet focusing is rated relatively high? What's going on? What am I missing?

I bought this camera 7 months ago and I absolutely love it for what I use it for. I live to shoot Lightning, astrophotography, long exposure etc. and the 6D shines beautifully due to its amazing low noise sensor up to ISO6400. The standard kit lens 24mm-105mm f4 L series is amazing. So sharp and accurate.

Where it lets me down is in the studio. In the field I manual focus everything, in the studio however I prefer to use autofocus at times. The autofocus on this camera sucks. Yes it can focus on the light of a full moon, but for everyday use it’s about 3 years behind the market. My guess is that the 6D came out after the 5dIII and Canon had to make sure that people still bought the 5dIII even though the 6D sensor is better in low light hands down. The 5DIII focus system is great!

With regards to the multiple exposure and HDR modes. Both are features that I think all serious SLR cameras should have moving forward. They are fantastic!

> And as is Canon's wont, they have opted for the allure of familiarity and consistency

Am I living on a different planet? I have a 5d2, T3i/600d, and now a 6d. With just the 5d2, I got familiar enough with the user interface to work in the dark.

But the three cameras turn on/off differently. The LiveView works differently. The Mode PASM works different. Many controls are relocated. Magnify is different. Re-assign buttons is different, etc. etc. etc.

I get it that the UI has to change with fewer thumb wheels on the 600d, and missing the joy-stick on the 6d However, the on/off changes, Mode, etc. seem like poor choices.

I really didn't expect to have a re-learning curve from the 5d2 to the 6d. If I forget a head-lamp, it really slows me down at night.

Seems more like "change for the sake of change" rather than compelling improvement. "If it ain't broke, don't fix it!"

Am I the only whiner that feels this way?

Does the 6D lack an anti-aliassing filter?

0 upvotes
l_d_allan

It has an anti-aliasing filter. AFAIK, I'm not aware of any Canon camera that doesn't have the AAF (aka OLPF?)

BTW: the reviews I read on the Nikon cameras is that lack of the AAF is over-rated. The 800e implementation seems like a joke ... pay more to have them put a compensating "something" over the existing AAF.

Seems kind of like a lens having a UV filter built-in, then paying to have an anti-UV filter on top of that ?

You can fix the green tint with one click in the white balance menu...set one click towards magenta, and the green goes away. Forever. That's ridiculous to switch brands for that. Better yet, shoot RAW, and who cares what the white balance looks like? Fix it in post.

Finally ready to make the jump to full frame after 8 years with Olympus DSLR's. After considerable research and gnashing of teeth I pulled the trigger on the 6D. I really wanted to go with the Nikon D 600 based on DP Review and various other reviews, based on features, output quality and MP, but the ongoing concerns over the sensor dust and oil spots and Nikons recalcitrant PR approach to these issues pushed me to the 6D. I just could not imagine investing $3k in full kit only to experience ongoing sensor issues. I am excited to experience the full frame format and take my amatuer photography to the next level.
How is Canon's photo management & editing software? Should I look into purchasing another package, and what does the forum recommend?

Fully agree with your comments! I was about to go to Nikon D600 but was so much disappointed with their no-customer (snob) oriented approach that eventually decided for the 6D. I couldn't be more satisfied for such a decision. I liked Nikon so much in the past (before digital era) they made so beautiful film cameras, but this is the past...the present looks different.
As for the software: I always shoot RAW and develop with Capture One and that's excellent for other cameras, particularly for Fuji X raw files, but for 6D RAW files I found out that Canon software (Digital Photo Professional) gives better results. The only drawback of DPP is that it is very slow.

After a long deliberation, I decided to upgrade from my 5Dii to the 6D. Some may call it a sidegrade or even a downgrade, but for me, image quality is everything, and the ablity to focus and shoot in low light is paramount. I'm very happy with my decision, and so far I don't miss any of the 5D line features. I'm getting shots I wouldn't have gotten with the 5Dii (maybe not even with the mark iii), and most importantly I can afford to upgrade every one or two years with the current price point of the 6D rather than three or four with the 5D. I'd rather have more frequent updates of sensor technology instead of being left with a better built, feature packed but obsolete camera for the same money.

@ Alwynj:
The difference is more obvious when you look at the brown fibers right on top of the color chart with the lady's face. Also the black and white squares in the corners are a lot sharper with the Canon, but perhaps the used Canon lens performs better resolving detail in the corners than the Nikkor used with the D600 what might explain the difference in detail.

I don't understand DP Review. Compare the Canon 6d and Nikon D600 and they'll have you believe that the D600 edges ahead in the high ISO dept, but to my eyes the 6d wins when I use the comparative tool. Images appear slightly cleaner and sharper (in RAW). Move the box to the face of the lady and see for yourself

Some of that may be because the comparison may be on a pixel vs pixel basis. A single Canon pixel may have lower noise than a single Nikon pixel, but there are many more Nikon pixels.

And I tend to get fuzzy when comparing crop cameras to full-frames. It can be "apples and oranges".

The 6D would never be considered a great camera compared to the 5DMk3. More than likely the compromises that make the 6D "merely a very good one" are those with respect to the D600.

DPR: Can you please insert a photo in ALL your reviews showing the AF sensor array? Thank you.

0 upvotes
Maddrew

Assuming we are looking into the camera's OVF horizontally, the vertical coverage of the 6D's sensor array is about 1/3 the height of the OVF, spreading from the centre AF point. The diamond shaped array is slightly wider, almost covering 2/3 the width of the EVF, but just almost. Shooting vertical portraits with extreme DOFs (like using the 50mm F1.2 L wide open) can be tricky, because the furthest points of the diamond AF array misses the subject's eyes (under normal compositions) a little too much. But to be fair, the 5D Mark III's high density AF array is not that much spread out either, especially when compared to Canon's APS-C EOS bodies.
