OK- I have a question...Just got my Canon 100mm macro(not IS) I didn't have a lot of time to play with it. These were the first few shots I took, but it seems to have really good focus but in a strip? Is that because of my settings? I was just wondering because in the spring when I want to shoot flowers & bugs I don't want the focus in a strip?? Thanks in advance for the advice
I only looked at the exif on one of your shots, but yes, settings play a huge role with this lens. When shooting 1:1 the DOF literally becomes paper thin, this is why you are only seeing a "strip" in focus. IMAGE LINK: http://www.flickr.com/photos/lenzfreak/11040094454/ Ladybug40
To get more in focus you really have to stop the lens down when you are planning to shoot really close. Unfortunately the trade off is a huge loss of light, either forcing you to slow your SS down, crank your ISO or both. You can combat this by using a flash, or adding more ambient light.
