Canon’s EOS 6D is a full-frame DSLR sporting a 20.2 megapixel CMOS sensor. In a clutter of APS-C sensor powered DSLRs the EOS 6D stands out with its full-frame sensor deceptively camouflaged as yet another small sensor camera. That is until you read the specs. The 6D does seem like an APS-C camera and that is probably the biggest USP of the camera, the small frame that houses a large sensor. Let’s find out more about it.


As already explained, the sensor inside this DSLR is a 20.2 megapixel full-frame CMOS (35.8x 23.9mm) one capable of producing large fine JPEGs of the size 5472 x 3648 pixels. Larger sensors are better when it comes to gathering light. Low light imagery is one area where the large sensor will come in handy. You also get shallower depth of field for the same composition, compared to something like the 7D.

Image Processing

The 6D is powered by Canon’s DIGIC 5+ image processing engine.


The 6D is slightly better in terms of AF sensors when compared to smaller cameras. This is a dated model in anyways and that shows up on simple things such as the number of AF points. The EOS 6D has an 11 point AF system.

Comparatively, the entry level EOS Rebel SL1 has a 9 point AF system. The center AF point on the EOS 6D is a cross-type. The 6D, however nails AF in most lighting situations. With that you have the iFCL 63 zone dual layer metering sensor.

The thing that is missing is the sensor based (on-chip) phase detection technology. This would have been a mighty help for shooting in live-view as well as when shooting videos.

ISO Sensitivity

The native ISO capability of the sensor is 100 – 25600. It can be further extended to 50 – 102400.

Still Shooting

The continuous shooting speed of the EOS 6D is only 4.5 fps when shooting at full resolution.

Video Shooting

Canon’s DSLR cameras are good video shooters as well. The 6D is no different. It can shoot full HD videos at a frame rate of 30 fps. You have both All I-frame (IPB) and H.264 (MPEG 4) options for compression. A maximum of 29 mins and 59 seconds can be recorded in a single clip.

You have the option to record sound via an external mic. A feature of the camera is that you have full manual control over the exposure and the sound levels. That way you can control the exposure, the depth of field of your footages as well as the sound levels for a precise treatment.

Rear LCD Screen

Rear LCD screen of the EOS 6D is a decent 3” with a resolution of 1040,000 dots. The screen does not articulate, which is disappointing. Neither does it have touchscreen properties with the ability to touch and focus. This would have been perfect when shooting in live-view mode. The LCD screen, however, gives 100% coverage.


The 6D enjoys good connectivity parameters with a built-in wireless connectivity and GPS. Built-in wireless ensures the camera can transfer images and videos when a wireless connection is available. With GPS location data of the images can be embedded seamlessly and then later accessed via a map application.

Build Quality and Weather Sealing

The 6D is strikingly similar to the design and looks of the mid-range EOS 60D. The layout and button styling etc., are all taken from this very popular APS-C system. The 6D retains a few premium build quality features that are otherwise retained for pro-grade cameras. This includes a pentaprism instead of a pentamirror. Coverage of the viewfinder is however only 97%.

The camera has an aluminum alloy and polycarbonate chassis and then on top of it magnesium and polycarbonate has been used for the exterior. Overall weight of the system is 770 grams.
