I am disabled and can't walk as well as I used to. My wife got me a microscope for Christmas with a Canon Eos adapter.
Shot with my Canon 5D MK II, 1/125 sec. f stop unknown, ISO 1600, focal length unknown. Lens is a microscope. I was very surprised to see what the edge of an African Violet leaf looks like. Looks very sharp compared to how soft they feel.
