#26
Well, as we state as often as possible: comparing lenses across different test systems is not valid. At least as long as we are talking about pure MTF numbers. You may still roughly (!) compare lenses by the rating of our MTF skale (poor-excellent), but one should be absolutely aware that there is way more than one factor (the lens) that influences the MTF results (AA-Filter, sensor design, demosaic and sharpening of the raw converter, etc). In addition, there are some design differences that make some properties easier or harder to achieve (like low vignetting on the M9... or good borders on the NEX7 Wink ).

So, since the OM does not fit on the M9, it will be difficult to compare directly. However, if someone is willing to provide the lens plus adapter for F-mount (or a Leitax modified one)... sure, why not Smile
