Robin Wong has compared the Panny 25mm 1.4 to the Olympus 25mm 1.8.

There are some interesting points. First, the Panasonic required a slower shutter speed at the same aperture, meaning there may be a difference in the way Olympus measures their f/stop and the way Panasonic does.

There seems to be very little difference in background blur, but there is a hair more with the Panasonic.

The Olympus lens was sharper at times, but not all the time. The Olympus lens did have better corner sharpness.

After reading this, I would choose whichever lens was cheaper, though you should note the Olympus lens is smaller and lighter.

The Olympus will work better on Olympus bodies if CA is a concern. It may be the reverse on Panasonic bodies.

This review demonstrates the points of made before on this forum (but usually people just get mad at me when I make these points).

Panasonic lenses do NOT work as well on Olympus cameras as they do on Panasonic cameras.

I'm noticing that the contentious issue is also the reported mis-focus of the PL25.

I always wonder whether issues like mis-focus relate to body-lens mismatches i.e. Pany lens on Oly body or vice versa. Theoretically, it shouldn't be an issue because we're talking about a standard, but reality tends to be different.

Anecdotally, I would say I have had mis-focus issues with my PL25 on my E-M5 than other lenses, but I also use it in those conditions because they will be challenging. This is not brand bias either, I own 2 Oly lenses and 8 Pany lenses.

Heard the same thing before about the purple spot issues on the 7-14 with the E-M5 and all the Pany body owners saying that it didn't exist.

I'm guessing that both manufacturers spend a significantly greater amount of time testing their own lenses on their own bodies than that of their partner("competitor") companies.
