Hi just got my Canon 100mm macro lens and tried a shot. I tried zooming in and seems to be blur. The setting was AV f2.8 on tripod as I was testing it and would like to know if it's due to lens blur or it's normal? I did some other shot in daylight using tripod with Auto Focus and when zoom in also blur? So don't know if it's due to camera shake or lens problem? Any advise. Attached is photo taken at night.
