To perhaps answer this question, shoot a series of pairs of images, each shot from the same spot, matching exposure, aperture, and ISO as much as possible, cropping the 135 to duplicate the FOV of the zoom and comparing the images side by side.

The OP suggested that since the 135 is a much faster lens, and sharp wide open, the iso would be lower than with the 70-350 lens and this what I'm curious about. I think with same aperture and iso, the 135mm would lose...but its the former argument that I'm curious about. I have 135 f2, and the 70 350 so I may just try it myself . According to the OP, The sony 135 is as good, albeit at a lower iso, when cropped to 350 equivalent.
