I usually shoot with my Canon 450D with the 60 mm lens from canon. I am often disappointed with the lack of sharpness I get when shooting macro. Is it because of my camera, lens, aperture, light?
Would be really interested to read what you have to say
One thing that will make it not so sharp is if you have your shutter speed to low, hard to say for you but when I shoot with a 105MM most of the time I am using 1/200th or faster. Also a very steady hand, sound obvious but true, I usually take the shot the split second the focus locks to avoid as much hand movement as I can and then take several shots, or more, you can then pick the sharpest of them all.
