Robin Wong makes it quite clear that he cannot be really objective on his reviews so such a comparison only makes sense for those who are aware of his bias.

The main thing here is that there are 3 domains where the oly lens appears superior and where the camera could make the difference:

-CA (I believe there is no CA corrections at all for panasonic lenses on the em1)

-corner sharpness (the em1 has profiles of the lenses and applies selective sharpness filters). This point has NOT been mentioned by Robin Wong.

-brightness (1/3 of a stop is quite a subtle thing in an uncontrolled environment and could be camera related as well )

The build quality is also to take into account : my 45 f1.8 is definately NOT on the level of my PL25 in this regard.

Definately seperate? (two English words in which I hate misspellings worst, and they often come together).

I got 45mm F1.8 in 2011, from very first batch and it still holds well. I don't get why people enjoy touching large chunks of solid surface, being it metal or hard plastic. The lens just works, as long as you don't use it as a hammer.

Let's bookmark this post and return to this when DxO Mark, Lenstip and SLR Gear reviews appear. I think, regardless of Robin Wong being Olympus employee it is clear than Olympus lens is a bit better at corners but Panasonic lens is slightly better in center. Otherwise the lenses are very similar, except for 2/3 stop aperture Pana advantage and Oly size advantage. And I think the future reviews will show exactly that.

Heck with CA on old Oly bodies, it is automatically removed by Lightroom. I know this because I used PL 25mm on E-PL5 and E-P3. It works just fine and AF is fast and reliable.

There are still some questions left about bokeh differences on background with bright spots, can't tell if any lens has an advantage.

PL 25mm misfocus issue is I think an operator mistake as I've never seen it on Oly bodies. I focus carefully, though.
Also, I think difference between F1.4 and F1.8 can be a bit more pronounced, but not sure about T-stops. In all other aspects it's a fair review, I think.

Now the new oly appears to be quite good, and looks like the better choice on an olympus body.

Time will tell, but I find it a pity that panasonic and olympus compete directly on the lenses. It seems that more and more, the m4/3 is loosing its advantage of having two manufacturers.

What's the point of sharing the mount if manufacturers are doing everything to prevent you from buying the competitor's lenses ?

Perhaps the point is that you are wrong and manufacturers don't do what you accuse them to do.
