olympus e30 or canon 40d?

[Anbesol]

I wonder how true that really is ? And what the numbers are with other brands ?

Or is it just something I hear repeated over and over about how the 4/3 sensor is "bad" because of it's size

Cheers, Don

It isn't "bad" about it, but it is what distinguishes it most from other DSLR systems. With that, a long list of pro's and cons. I personally much prefer the 3:2 aspect ratio in and of itself (as well as all the other benefits of the APS sensors), but I can see the appeal of smaller, lighter lens and bodies, and more telephoto reach in crop factor.

Brings me to another thought - I was wondering about how the crop factor worked for Olympus, I know its stated 2x, but the 35mm equiv being a 3:2, it could only be a 2x crop factor either horizontal or vertical. I assume they measured the vertical - which would make the horizontal crop factor more like 2.4x. If anybody knows specifically please clarify, thnx, just a random thought I had today.

It's measured diagonally. It's 2X on the diagonal, slightly more than 2X on the horizontal, slightly less than 2X on the vertical.
