I occasionally mention how shallow the plane of focus is when I’m shooting bees. And the closer the lens is to the target, the narrower that plane becomes. Consider the first picture: I was really close to this one…the bee nearly filled the screen. And I missed the bee with the focus and caught the tip of a hyacinth blossom. And the bee is…a blur.
I was a little farther out with the lens in the second picture and managed to get the pollen basket in focus. But most of the rest of the bee is not tack sharp.
So…in addition to a great look at a bee (in the second picture, at least), I guess you get some perspective (again) in this post.
