This previous week I was happy to be out shooting with a local photographer Jason Thomson. We set out to see the differences in shooting stills with the Canon 5D and the Canon 7D. We also wanted to see if the small sensor in the Canon 7D could over come the 5D’s larger sensor advantage in low light with a slightly faster lens.

We chose twilight shooting to dark scenarios. Both cameras were set up with the same attributes.

 

  • ISO 800
  • Shutter Speed 125
  • Picture profile Standard.
  • Lens 50mm

The only real difference was F-stop in the lenses. The 5D had the cheaper 50mm f/1.8, while the 7D was fitted with 50mm f/1.4. Now it may seem that the 5D with its larger sensor would come out on top. But after working in various lights, we were both surprised to see the difference.

Now this was by no means an exact science comparisons. We just wanted to compare lighting situations against larger senors and lenses. With only .4 of an f-stop difference, and ignoring the the  Canon 7D crop factor,  it proved out perform the 5D in low light situations.

We were both shocked at the results. We immediately assumed the 5D would have come out on top given the f-stop difference was minimal. However, It really continues to show that a proper lens is always important. (Check out my review of the Canon 50mm f/1.4 here. ) Jason and I plan on following up with some more more extensive testing. But in the mean time what do you think is more important camera body or lens?
