    Cons: busy (poor) bokeh

    Pros: good optical quality, small size, great match for smaller m43 cameras

    Summary: This is a good lens and I was using it as a _walk-around_ lens, but the bokeh was not very pleasant so I switched to Olympus 25mm f/1.8 instead.

    Cons: Slight CA Issues Soft Corners unless stopped down a ways Not silent for video

    Pros: Super sharp in the center from wide open on The corners come around by f2.8 Great color rendition Instant focus on the newer Panny bodies.

    Summary: This is one of the "No Brainer" lenses if you own a Micro 4/3rd system. A virtual MUST HAVE for portraits and lower light shooting. The svelte size and weight make this the go to street lens as well.

    Cons: The lens changes length when it focuses. I fear for its sturdiness compared to fixed length ones.

    Pros: Good brightness, image quality

    Summary: Rocks!

    Owner since: 3 months
    Price: £240
    User profile: Amateur

    Cons: A bit over-priced perhaps, but otherwise none.

    Pros: Fast, extremely sharp and bright with good colour rendition. One of the few stand out lenses I've tried that because of it's compact size and quality fully justifies the choice of the M43 system. Hopefully this will set the standard for others to follow.

    Summary: Virtually every review I'd read before buying this lens was highly favourable and I must agree. Not an essential purchase if like me your photography is mostly outdoors in reasonable light, but a valuable addition in any case. Very few of these lenses become available second-hand and with good reason.
