The NASA claims on image quality are laughable. No matter the quality of the glass or the light sensitivity of the CCD, a one megapixel digital image is nowhere near the overall quality of a standard 35mm image much less IMAX quality.
The negative area of an IMAX camera is 2.772” X 2.072” which is almost as big as some of the smaller digital cameras on the market! It’s a 56mm acquisition and 70mm projection format.
Now, if they said the images captured by the rover’s digital camera offered the same (or even better) clarity per megapixel that would be a different matter altogether. I’d buy that. But that’s not what they’re saying.

Actually...that should be 65mm acquisition and 70mm projection. Damn dyslexic fingers.
