Thanks, Eric.
The two berries in the second photo show interesting optical effects. I tried to focus on the larger berry, but there was too little depth of field to put the sepal (brown triangular thing in front of the berry), the front of the berry, and the small projection on top of the berry (pistil) all in focus. The photo I posted showed what I decided was the best compromise focal zone. Even so, focus is a bit soft due to aberrations; remember that the lens is on extension. I get a slight sense of almost a 'glow' about the berries, which may be due to spherical aberration.
