The difference between the full frame and crop sensors

by planetmitch10 Comments

The other day, Philip Bloom tweeted the video below which was shot by Mike Collins (whom I met at the Canon EXPO) showing the difference between the full frame Canon EOS 5D Mark II (reviews) and the 1.6 crop factor Canon EOS 7D (reviews) using the same lenses. Tho the title of the video talks about comparing lenses, in reality, what it is really showing you is how the same lenses are impacted by the different sensor sizes.

Since the 7D shares the same sensor with the Canon Rebel T2i/550D and the new Canon EOS 60D, then of course this comparison applies to those cameras (and any other camera with a Canon APS-C size sensor).

This is a short test with the tripod in the same spot switching between prime lenses to show how the crop affects the 7D. The subject, ace stand in Chris Clement, was roughly five feet from the camera. This isn't meant to be an aesthetic test to show the difference in image quality between the two cameras. It's a down and dirty field guide for myself and the other shooters we work with so we can quickly figure what lens we want to use on each camera.

We go from 20mm all the way to 100mm with a Lensbaby composer thrown in at the very end.

Our thanks to @mikespins and his crew for posting this!

So, post your experiences in the comments now.

  2. You don’t get the same compression with a 10mm lens as you do with a longer focal lengths….so while you may still fit everything in the frame on a cropped sensor, the bokeh and compression isn’t going to be the same.

  3. What I prefer 7D more than 5D mark II is 7D have more DOF at low light condition at same 35mm equivalent focal length =)

  5. This is stupid, it compares apples and oranges. It should have compared 20mm with 35mm and so on. The it would have been a fair comparison and people would have realized the difference.
