The closest focus distance of the 100 F2.8 is about a foot and I think that I was pretty close to that limit. The background was also about a foot or foot and a half away. The closer you shoot with a lens compresses the depth of field. So at one foot, even at F14, there is only a relative shallow depth of field at that distance. All I got in focus was the top of the buds and no more. I had to jack up the ISO to use F14.


I was out looking for frost on leaves and the snow flakes caught my eye. I'll try to find some 100 macro flower shots using the 580EX. (That was two seasons ago!)
