I don't think much of it except: what aperture was the Leica shot at? The telecentricity of the Zuiko is obvious: sharp into the extreme borders. The contrast and color saturation is clearly better on the Leica.
Does the corner sharpness of the Leica improve at apertures like f/8?
I think 35mm is a bit of a weird focal length for m4/3's anyway: a bit short for portraits and not suitable as a walkaround lens like a 17/18/25mm would be. |

You've never heard of corner smearing with Leica M and other rangefinder lenses on m4/3's camera's and the reason why Olympus makes their lens designs telecentric? It has everything to do with the angle at which the light hits the sensor in the corners, which can be very steep with non-telecentric lenses. Digital sensors with microlenses don't respond well to this, whereas film didn't really have that problem. This is also the reason why it was so difficult to make the sensor of the Leica M9 (they did something special with offset microlenses I believe, to prevent dark and smeared corners).
Edit: oops, I thought yadisl was using a Leica M lens, but it's an R. Then I don't really understand why the corners look so bad. That shot with the Leica must have been take wide open then?

yes, very important remind
it is important to test a lens on film before sending it to bin _________________ T* |

I was curious about what this means. On the sample above with the Leica lens, I see corner and edge softness, while the Olympus lens is sharp throughout - is the softness what is expected from a non-telecentric lens? ...and if it is a softness, how does this happen? Is it refraction because light is hitting the sensor and the filter at oblique angles and bouncing around or...? I suppose I'll have to go re-read the 4/3 site, but although I am convinced of the high quality of the entire line of Olympus Digital lenses, I have alway assumed that "telecentricity" was just a new bit of jargon introduced to confuse me which I began to ignore as I discovered more and more MF lenses that worked well. |

check this link
we could conclude that telecentric lenses are needed for digital
but sensor have also other problems like vignetting
vigneting is much worst in digital than film and have the same origin, sensor only see straight rays
when the sensor microlenses will 'see' non straight light, non telecentric lenses will work fine, like they work today on film _________________ T* |
