Actually, I have purchased the pro version of the Reikan software.

Unfortunally, my 85mm and 50mm f/1.8 primes show different correction values at close range vs distant range. I.e., a single MFA cannot correct them for all distances. I was under the impression that Canon service had more parameters at their disposal, meaning that they could do more than the MFA implementation in my 7D allows.


My 7D will not nail a focus with the 50mm f1.4, 1.8 or the 85mm wide open (only stopped down). I am in the same boat even after multiple repairs by Canon....I am moving on, selling this POS. Good luck!
