OK I am going to give it a rest. Having made your purchase the die is cast and it is up to you how well it is used. To my way of thinking the only abberation not influencing MTF is distortion and that is listed seperately. In addition to that field illumination is also important.
Unless as a result of damage or of a faulty lens slipping thru the system one is fortunate because almost any lens made in the last 30 years is quite a marvelous instrument.
If one wants to be a fanatic abiut lens quality, in my opinion, they should do it with enlarging lenses because that is the most important lens you are likely to own.
Please, no remarks about CZ enlarging lenses.
