    Cons: Poor corners, especially wide open at 18mm Distortion at shorter focal lenghts Must change to MF to attach/detach lens hood or attach:detach to/from camera.

    Pros: If you have a Canon D30, D60 or 10D it's a great low price solution for a wide lens. Also works on other Canon APS-C bodies. Performance not bad when stopped down to f/8 or 11.

    Summary: Great value for money. Be aware of its limits and work around them for best results. Comes with lens hood.

    Cons: weak, not so sharp in the corners, colours not so brilliant,plastic lens

    Pros: stopped down you can use it for close-ups

    Summary: between all my lenses for Pentax digital;I've used it sheldom.original kit lens of the camera manufacturer is quiet better. A bit disappointing for a great lens name

    Cons: AF slow and very unreliable on a Canon 10D quite heavy distortion and vignetting at short end not very sharp (see summary)

    Pros: Build quality reasonable considering the price

    Summary: Despite being designed for crop cameras, this lens can be mounted on old Canon DSLR with EF Mount such as the 10D, D60 etc. where there is no ample choice of true wide angles. Wanted to give it a try for this reason and borrowed one. Turned out to be a decentered lemon. Not recommended.

    Cons: Not so durable build quality, but better than EF-S 18-55. AF is a little bit slow and very noisy.

    Pros: Sharp and very good colors.

    Summary: A good kit lens for FourThirds, but Zuiko optics are better. Not so bad at all.

    Cons: - Not terribly sharp. - Slow max. aperture

    Pros: - Not really bad unless you abuse it. - Built better than comparable kit lenses.

    Summary: A bargain bin kit lens which I found quite usable in daylight. It's in about the same class with the old Canon kit lens, and clearly better than the KM 18-70.
