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.

I think Robin Wong just fooled you all. He minimized the differences in the background blur by carefully adjusting the framing of the shots. Were you looking at the out-of focus areas? Good, now please look at the in-focus images.

Olympus is (according to the Robins observations) a wider lens... So the man's face should occupy smaller part of the frame if shot from the same position, or the same part if framed correctly for comparison. What do we actually see? The man's face is bigger in the Olympus shot! Look at the ear crop in the cropped-frame comparison to compare the relative image sizes.

Obviously Robin got closer to the target for his Olympus shot, and naturally focused closer too. Of course the background blur is exaggerated there, and the differenced with a faster lens successfully minimized/hidden!

The same applies to the market shots: the pile of red peppers is obviously photographed from closer distance using Olympus than Panaleica, putting a faster lens at disadvantage.
