    18-55 Kit lens sweet spot

    Hi guys,

    Just wondering if anyone has found the "sweet spot" for this lens

    I have been fidling around with different apetures and focal lenghts but I still dont have a nice crisp shot

    You probably have no experience with DSLRs, most DSLRs give results that ar e alittle bit less crisp than other digital cameras because they process the photo less (apply less sharpening for instance). This is on purpose, because sharpening a photo will introduce artifacts that you cant take away anomore, so the photos are kept in a state that you can easily process them on your computer the way you want to.

    You can of course adjust the settings of your camera and increase sharpness and saturation, giving a more crisp feel out of camera.

    Your kitlens is least sharp wide open and you should use apertures between f5.6 and f16, above f11 the sharpness will probably go downward again.
    Of course the depth of what appears sharp in the picture will increase with smaller apertures (bigger numbers).

    Thanks Coldrain,

    True this is my first DLSR

    So what you are saying is all those awesome shots that people post on the forum here have been adjusted after shooting?

    Obviously better lenses will get better results

    They don't post full size full resolution photos, and so you can not see the pixel per pixel quality... something you do see on your own photos. Also, yes, most photos you see are adjusted in one way or another. If you do not want to do that, bump up the contrast and saturation to your liking, and maybe the sharpness.

    And yes, of course it is true that better lenses give better results in colour and contrast, and can be sharper.

    Well's here's a full size image taken with the kit lens at f10. I'd say it's OK for a $100 lens:

    In fact all the images in these galleries were taken with the kit lens:

    Stopped down it's not that bad.

    The kit lens holds it's own. Here are some recent pics from the Cape last weekend. Some USM and bumped the contrast a little:
