    Just because we can! Nothing too technical about this, I just wanted to see the difference with the 2 lenses.

    I'm sure some people have wondered about the difference out there, so I did a quick little test with the E-PM1.

    First shot, OM 50mm 1.8, ISO 200
    50mm1.

    Now for the 45mm, ISO 200.
    45mm.
    Really, really impressed at the rendering of the 45mm, really great.

    I also shot a couple at 1600...once again, just because we can.
    50mm, may have missed focus slightly
    50mm1600.

    45mm
    45mm1600.

    That's quite a strong yellow cast on the 50mm. Is it radioactive?

    It was under pretty dim light, I think AWB just manages to work better with the digital lens.

    Adam,

    I did something similar (also unscientific and not well controlled) with a nondescript legacy 50mm, an Oly 14-42mm and the 45mm on my EPL1.

    Here's the general scene. I took the same photo with all three lenses. Since it was a bright day, I set the apertures all to f5.6, which negated the 45's main advantage. It's also a naturally contrasty scene.

    Here's three crops, all at 100X. Which of the three is the 45mm version? I looked hard at all three images and really didn't see much difference in the edges and center.

    Not saying my other two lenses are as good as the 45mm, but in good light, they work OK.

    Is the 3rd the 45mm? Whichever lens it is, the 3rd image is significantly sharper and more detailed than the first 2 at 100%

    Agreed - if the 3rd is the 45mm I'm sold. Subtle differences, but definitely sharper.

    Yes it is the third image. Kit zoom is the middle one.

    The only negative I have on the 45mm is that the front ring has come off on me twice. Perhaps I should have left the blue tape in place.

    that probably would just make it worse as the tape hung off the side =P I'm contemplating gaffers tape. It's getting pretty annoying. Or leaving it off, but then it feels and looks incomplete, heh
