I'd be interested to see one of your full frame raw images at native resolution. Without seeing that, I couldn't say for certain, but I suspect your system limit is charge diffusion. For a given focal length, that's as good as it gets from the perspective of the application of opto-mechanical principles pertaining to ccd imaging.
