This seems to contradict previous statements. Photozone always said that the lens data IS comparable in respect of the same lens mount system. Consequently, if you know how (i) Canon lens A performs in relation to Canon lens B, (ii) Olympus lens A performs in relation to Olympus lens B, and (iii) Canon lens A performs in relation to Olympus lens A, then you can also conclude how Canon lens B will perform in relation to Olympus lens B. As already mentioned, I am not talking about corner performance.
Pratical conclusion: I already agreed that this test would be rather academic and would probably not result in a lot of revenues/clicks. It would only answer the frequently posed question whether Canon glass is clearly inferior to Nikon or Olympus glass (or vice versa). I doubt that there are huge differences.

No, they are only comparable with the same test system.
A system is a combination of a specific DSLR + Post-Processing.
We never stated something else - see the Lens Test FAQ.
This is, BTW, true for all lens testing websites including the big one.
Some do still attempt to allow comparisons but this is technically invalid.
