7D vs 6D
Or Crop Sensor vs. Full Frame
First off, why the 7D vs 6D comparison doesn’t really make sense: The Canon 7D and the Canon 6D are cameras that are designed for two different user segments. But as the prices of these two DSLRs from the same manufacturer are quite same (at least the body), let us look at the differences and see which one is the best.
The Canon EOS 7D is distinctly aimed at photographers who are more interested in a smaller sensor, more affordable and yet decently powerful DSLR.
The Canon 7D: Crop Sensor
The new 7D mark ii has a 20.2 megapixel APS-C CMOS sensor. While the resolution has slightly improved over the older 7D which had 18 megapixels, what’s eye-catching is the dual DIGIC 6 image processing technology.
Comparatively, the 6D had a DIGIC 5+ image processing technology. With the new 7D mark ii you should get a much better low-light performance with reduced noise signature in your images.
Please bear in mind that the 7D mark ii (and the older 7D) is an APS-C DSLR with a crop sensor much smaller to that of the full-frame sensor inside a 6D.
However, since both the new 7D and the old 6D has the same resolution, Image sizes are going to be the same. In fact, the largest image size you should get is 5472 x 3648 pixels.
Auto-focusing: The New 7D vs 6D
The older 7D had a 19-point all cross-type AF System with a center AF point that was dual cross-type of f/2.8.
It was much better compared to the 6D which only had an 11-point AF system with a single cross-type center AF point of f/5.6.
The Canon EOS 7D wins!
But the new 7D mark ii beats both hands down. It has a 65 point all cross-type AF system with a central dual cross-type AF point of f/2.8.
With the new 7D mark ii Canon has employed the Intelligent Subject Analysis (iSA) which has an independent RGB+IR sensor for faster and more accurate auto-focusing, better detection of subject’s faces and colors.
Drive Speed: The 7D Wins!
7D does 10 fps vs. 4.5 fps of the 6D
The 7D always satisfied the voracious appetite for photographers who love spraying. If you love sports and fast action photography the 7D was always a safer bet compared to other APS-C DSLRs.
The new 7D mark II simply upped the game from 8 frames per seconds (fps) to a mouthwatering 10 fps.
The 6D comparatively finds itself beaten for speed with a drive speed of 4.5 fps.
Bound with the continuous drive speed, the 7D mark ii can capture a phenomenal 1090 jpeg images or 31 RAW or a combination of 19 RAW+ JPEG images in a single burst before the buffer overruns.
Screen size & Viewfinder: Canon 7D vs 6D
Winner: The 7D gives you 100% Screen size & Viewfinder
Both the new 7D mark ii and the old 6D has a 3” LCD screen with a resolution of 1,040,000 dots.
While the 6D only gives a 97% viewfinder coverage, the 7D mark ii gives a 100% viewfinder coverage. Bigger frame coverage allows you to compose an image better without having to worry about catching anything unwanted in the final image.
With the 7D mark ii, you get exactly what you see through the viewfinder.
Dual Pixel CMOS AF system
Better video with 7D
This feature is not new to Canon systems. We have already seen this in the Canon 70D and the new Canon 80D. With this technology the 7D mark ii has a significantly better auto-focusing capability when shooting videos compared to the 6D and the older 7D.
