    Unlike different lenses I find the focus is soft in various bits when using the Canon 100mm Macro lense......
    Finding it hard to figure out why....tried MF/AF, checked the distances etc
    Tried various P/Auto/M/Macro (not really up enough on M yet)
    This is not a C&C. more like HELP!

    I learned alot from the Cricket thread but def need help/tips on these pictures, I ended up getting into a foul mood after this session.

    As you get closer your available depth of field gets narrower and narrower, those shots look as I would expect. Even using a small aperture (high f number) you will still have very little DOF.

    A better explaination here.

    If your camera has live view, this is invaluable for macro

    Well i don't know what camera you have but, did you check the Focus points in the screen? is it all or just some spots?

    if you want all focus you have to set the camera focus points to be used all at the same time, and also as you get closer to the object the camera can't focus some parts as they are too close...
