Canon EOS 6D Sensor

The Canon EOS 6D Sensor:

It's a healthy 20.2 MP Full-sized CMOS sensor.  

It's data is handled by a Digic 5+ processor. 

14-Bit A/D Conversion (Analog to Digital)

The introduction of the canon 6D was very significant.  It is a great opportunity for photographers to enter the high-quality world of full-sized-sensor digital photography.  

When the original 5D came out, I was thrilled to get a full sensor in a camera body that didn't come with the bulky size and price of the 1D series of Canon cameras.

The EOS 6D bridges the divide even more between cropped sensors and "professional full-frame bodies.

Canon EOS 6D Sensor Bit Depth

One of the big benefits of the 14-bit conversion is that there is more color and brightness information in each RAW file.

For those techies that really want to know.

This little chart show the relationship between the bit depth and the number of shades of color represented.

A 14-bit conversion gives you 4 times as much information as a 12-bit.  

Most original digital cameras only had 8 bits or only 256 shades of a color.

In practical terms, more bit depth means smoother gradations and transitions within an image.  

The results show most readily in photographs where there are solid areas that change in brightness, such as the gradation from light to dark in a beautiful blue sky.

It also shows up in portraits where the transition from bright highlights to shaded areas.

Another important upgrade for the Canon 6D is the superior 9-point focusing grid.  Even the Canon 5D Mark II only had a 9-point focusing grid.

Canon 6d Sensor Size Comparison

You can see how much bigger a full-frame sensor is compared to other popular formats. You can also see why I like my G1X Mark II so much.

Size matters and the G1X Mark II has a very large sensor for such a small compact camera body.

The use of WiFi and GPS combined with the Digic 5+ processor of the 6D, and the handling all of the data produced by the big 6D sensor, create a need for extra battery power.  

It might be a good idea to have a Canon 6D battery grip added to your collection of accessories.
