How does the sharpness of the positive compare to the original negative ? Could you check it out with a loupe for us if it there is no obvious difference ?

I realise the emulsions are quite thin (perhaps 10-15um), but there would also probably be some supercoating/anti-scratch layer on top of that too. I guess due to diffraction the positive can never be as sharp, but I wonder what practical results you are getting.
