Fig 11. Aperture f5.6 comparison (three lenses)

100% crop of the quail head. I focused the center sensor on the eye of the quail. Even at a 100% crop is difficult to detect any differences in the optical quality of the lenses tested.
Click on "original" on the "other sizes" line below to see the largest image. The focal length of the 100-400mm lens was set at 400mm.

other sizes: small medium large original
