Hi everyone. I just gotten my first macro lens, a minolta 100mm f2.8 RS 1:1 macro, and promptly took it out to find something to shoot. Prior to this I've already read numberous guides on macro photography on the net,and know about the extremely shallow dof and I set about using f20 on my camera. However even at f20, I still find the dof way too shallow. I took some pictures of a dragon fly and it turn out blurry.
Just wondering what could be the cause of the images being blur? My shutter speed is 1/80 but image stabilizer is on. Aperture f20. No tripod was used as I'm trying to shoot living things... so is the blur cause by insufficient shutter speed, incorrect focus (mf) due to shallow dof,or is it diffraction caused by using to small aperture?
I have an external flash, but didn't use it when taking the photo of the dragonfly, as I'm worried the lights will scare it away lol. Should I hv use the flash?
