Some comments on the recently announced Panasonic lenses point to a very interesting article which explains why the aperture values are not the same on CSC, crop size, full frame, medium format ... this brings me to the question:

The aperture of f2.8 on the Sigma DP Merrill cameras, what aperture would this be on a full frame camera?
