Viewfinder size measures, rougly, how large the image appears in the viewfinder. In general, larger values are better.

Manufacturers sometimes advertise this value as viewfinder magnification, which has a very specific meaning: the amount of magnification observed when viewing a scene through the viewfinder on a 35mm (full frame, in DSLR terms) camera with a 50mm lens vs. viewing the same scene with naked eye. This definition, however, is problematic when comparing digital cameras with different sensor sizes. Snapsort corrects the published viewfinder magnfiication to account for crop factor, thus enabling meaningful comparisons of viewfinder size across cameras with different sensor sizes.

Viewfinder comparison

The following image shows the relative size difference of a scene viewed through viewfinders of a number of cameras.

Relative size of viewfinder across a number of cameras.

Details for geeks

To come up with our viewfinder size number, Snapsort uses the following forumla:

    viewfinder_size = viewfinder_magnification * (1 / crop_factor).

Yeah, Canon crop cameras have some god-awful viewfinders. Starting with the D80, Nikon started to get it right. The 7D improved a little bit, but the rest of the Canon crop cameras still lag behind.

Very helpful! I remember shooting with an AE-1 and being blown away when I picked up a working OM-1 at a thrift store for $3. I didn't realize at the time I was looking through the largest slr viewfinder... ever? Now I'm stuck with a 300d and it kinda blows.

Maybe you should include also viewfinder coverage in comparison?

For a more complete comparison you should also show the smallest Nikon viewfinder size (D50 & D70) and a medium one (D60 & D40) and the largest DX viewfinder (D7000).  Good work!
