Spent some time at Balboa Park trying to play around with depth of field on my new camera and lenses.
This first example shows a comparison of how finely you can control the depth of field and focus points. This is a pitcher plant (a totally cool carnivorous plant), with the focus points in two different spots (the first on the little “teeth” on the left, and the second on the bottom “lip” on the right.
In this next photo, I was trying to reduce the depth of field as much as possible. It’s taken at a focal length of 250mm, and a f5.6 (as wide open as my lens gets at that zoom). As you can see, the DoF is impossibly shallow. I thought I had the fig in focus, but it looks like I focused in on just the upper right of the stem, which left the fruit itself blurred.
