Just to mention - if someone is willing to provide Olympus Zuiko lenses for testing I would be more than happy to do so ...

Will you also test the 50mm/2.0 Macro?

Well, one motivation for the tests is a guidance for MTF users. The 50/2 may be nice (and possibly tested at a later stage) but the other lenses are more interesting because there's no equivalent offer.

A strange selection of hugely expensive as well as big and heavy Zuiko lenses, which have been built for a by now pretty obsolete system. The 50/2 is said to be one of the sharpest on this planet and would surely be of interest. It is also somewhat more affordable than the other stuff on your list. Finally, there are some equivalent offers around when you have the MFT mount in mind:
Olympus Zuiko 7-14mm f/4 - one would probably prefer the Pana 7-14, a native MFT lens, and way cheaper too.
Olympus Zuiko 150mm f/2 - the Canon 135 mm f/2.0 L is very nice, at less than half the money and weight.

Leave me a couple of hobbies, please. :-)
MFT is done by Sebastian so we are talking about two different queue here.
Besides this is a free service so what is so bad about these tests anyway.

How do the Olympus 150mm f2 and Canon 135mm f2 L USM compare???
The Olympus is 300mm f4 full frame equivalent.
So, it would be more sensible to compare it to a Canon EF 300mm f4 L IS USM.
Or on APS-C? Then it would be more sensible to compare it to a Canon EF 200mm f2.8 L USM II.

Klaus mentioned "equivalent offers" for MFT. The 135 mm Canon is a 270 mm lens on MFT while the Olympus delivers 300 mm. Understood?

No, I would also compare the Zuiko to the 200L (APS-C) or 300L (FF).
In any case - there's no MFT offering like it or the 14-35/2, 35-200/2 and 150/2.
You may debate whether the 7-14 makes sense but that's a very personal interest.

No, I still do not get it. In no way the Canon EF 135mm f2 L can be considered workable on MFT, so you can't even consider it equivalent there. So.. not in the MFT context, not in the APS-C context, and not in the FF context...

The Canon is about as workable on MFT as the 150 mm Olympus. Both need an adapter, both would not provide AF functionality (on Panasonic MFT bodies MF only, on Oly MFTs AF may work to some extent with the Oly lens, but it is likely to be slow as mud and/or inaccurate without correction by manual focusing).
