Introduction
As soon as you pick up the 20.2MP Canon EOS 6D you notice that it's quite a bit different from the Canon EOS 5D Mark III. It's smaller for a start, being similar in proportions to the Canon EOS 60D. And although it still feels pretty durable, it doesn't feel quite so tough as the cameras further up Canon's DSLR line.
There's also no mini-joystick multi-controller for selecting the AF point, instead there's a navigation pad inside the dial large dial on the back of the camera.
The menu system also looks a bit different, with a long list of option tabs across the top of the screen. All the usual features that you would expect to find in there are present, with one or two new additions. The custom functions section, for example, has an Autofocus option, and it's possible to adjust how the AF system responds to a change in subject distance.
This makes the Canon EOS 6D a more versatile, customisable option than the Canon EOS 60D for sports photographers - although the maximum continuous shooting rate is only 4.5fps. There's no M.Fn button next to the shutter release for adjusting the focusing options, though.
There's an interesting option in the Playback menu that enables you to create a photobook direct from the camera. This is a pretty exciting option that ties in with Canon's Project 1709 cloud storage plans, since this will enable photographers to order prints and books to be made via the internet.
There are 'only' 11 AF points, but they are pretty well spread across the frame, and the system is as responsive as we have come to expect. The subject is brought smartly into focus after half pressing the shutter release, even when light levels are quite low.
Although the Canon EOS 6D has HDR capture like the Canon EOS 5D Mark III, this is a JPEG only option, so it's not quite as exciting for serious photographers as the raw HDR capture option of the Canon EOS 5D Mark III.
Making connections
Wi-Fi connectivity is a key new feature for the Canon EOS 6D. We weren't able to test this with the pre-production sample that we got to use, but it was good to see that you can create a nickname for the camera to make it easy to recognise when you're trying to connect.
We look forward to testing this function when we get a full production sample camera in for our Canon EOS 6D review.
Being able to upload and share images directly has obvious advantages, and it ties in nicely with Canon's Project 1709 beta cloud storage program, announced at the same time as the Canon EOS 6D. This enables you to store, index and view images on a range of devices, wherever you are - provided there's an internet connection.
An iOS and Android app also makes it possible to see the Live View image on a smartphone screen and trigger the camera's shutter remotely. We have yet to see if this will also enable you to remotely adjust key aspects such as the exposure or the focus point, but it's a step in the right direction, especially for wildlife and macro photographers.
The Canon EOS 6D also has GPS technology built in, which enables images to be tagged with location data as they are captured, making it easy to identify where they were taken post-capture, which is useful for travellers and forgetful photographers.
Even when the camera is turned off, the GPS can record your journey, and it will be interesting to see how this impacts battery life.
Composing images
Unlike the Canon EOS 650D, the Canon EOS 6D doesn't have touchscreen technology, and the 3-inch 1,040,000-dot Clear View II LCD screen is a fixed rather than an articulating unit.
This provides a decent view in a range of light conditions, but predictably direct sunlight is still a problem, and it's a shame that the screen can't be tilted.
One disappointment is that, unlike the Canon EOS 5D Mark III, the Canon EOS 6D doesn't have a rating button, so images can only be assigned a score out of five via the menu. It's an easy enough process, but it's not the same as simply hitting a button to rate an image and make it easy to identify when you download it to a computer.
Being a DSLR, the Canon EOS 6D also has an optical viewfinder, and this provides a nice bright view without any obvious dimming or corner shading.
Memory
One key difference from the Canon EOS 5D Mark III and Canon EOS 7D is that the Canon EOS 6D only accepts one SD card.
While this enables the camera to be smaller, we wonder what the implications will be for dedicated Live View users and video shooters, since there's bound to be lots of heat generated, which could result in extra image noise or recording shutting off. We'll be looking at this when we get a full production sample in for testing.
Speaking of videographers, these users will be disappointed to learn that the Canon EOS 6D doesn't have a headphone port to enable audio to be monitored - there's just a mic port to facilitate cleaner sound recording.
Image quality and resolution
As part of our image quality testing for the Canon EOS 6D review, we've shot our resolution chart. These images were captured using a full-production sample of the camera.
If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the Canon EOS 6D is capable of resolving up to around 26 (line widths per picture height x100) in its highest quality JPEG files.
For a full explanation of what our resolution charts mean, and how to read them, check out our full explanation of our camera testing resolution charts.
Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:

Noise and dynamic range
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.
Here we compare the Canon EOS 6D with the Nikon D600, Canon EOS 7D, Sony Alpha a77 and Canon EOS 5D Mk III. These images were captured using a full-production sample of the Canon 6D.
JPEG signal to noise ratio
These results show that the Canon EOS 6D's JPEG files have a similar signal to noise ratio to those from the Nikon D600 and Canon EOS 5D Mk III throughout the sensitivity range, beating those from the Canon EOS 7D and Sony Alpha a77 at every ISO setting.
Raw signal to noise ratio
The signal to noise ratios of the TIFF images (after conversion from raw) from the Canon EOS 6D are again very similar to those from the Canon EOS 5D Mk III and Nikon D600, although the Nikon's performance trails off at higher sensitivities. The 6D beats the Canon EOS 7D and Sony Alpha a77 at every ISO.
JPEG dynamic range
JPEG results for dynamic range are more confused than those for signal to noise ratio, with the Canon EOS 6D performing comparatively poorly at low ISOs, lagging behind the Nikon D600, Sony Alpha a77 and Canon EOS 5D Mk III but still beating the Canon EOS 7D. In the mid-range it picks up while some of the other cameras drop off, making it the second-best performer for a while, until it ends up on top by the upper end of the sensitivity range.
Raw dynamic range
This chart indicates that TIFF images (after conversion from raw) from the Canon EOS 6D have a similar level of dynamic range as the JPEG images. The 6D starts out producing less dynamic range than the Nikon D600 and Canon EOS 5D Mk III, but a greater range than the Canon EOS 7D and Sony Alpha a77. But by ISO 400 it is the second best performer behind the Nikon, and at higher ISOs it takes the lead by a significant margin.

Early verdict
All things considered, the Canon EOS 6D looks like a pretty decent DSLR, with the Wi-Fi and GPS technology being nice bonuses for the average photographer. At 20.2MP, the resolution is not a great deal more than that offered by Canon's APS-C format DSLRs, but there should be a significant image quality advantage.
Those upgrading from a Canon EOS 60D should find it pretty straightforward, without any major handling changes. You'll also be happy that the Canon EOS 6D uses SD format cards rather than CF, but we wonder whether this could be a limiting factor for video shooting.
Priced at £1,799/$2,099 body only or £2,519.99/$2,899 with an EF 24-105mm f/4 L IS USM kit lens, the Canon EOS 6D is appreciably more affordable than the Nikon D600. But the figure still feels a little on the high side for a camera aimed at enthusiast photographers, and many will wait a few months for the price to come down.
Our full review is no underway and will be published here soon.
