As analog photographer me were such aperture has always been important. Unfortunately, this is true only to a limited extent for digital photography. Nevertheless, I considered the panel whether the extremely small aperture of the lens would be useful. Practically I did not take any positive experience. In addition, the panel can not be mounted vice versa - very annoying. In addition to it, no camera case fits more to a lens with lens hood - double annoying. The optical performance of the lens at maximum aperture with backlight is also catastrophic - triple annoying (if the panel could help the lens dirty anyway everything). Thus, there is in my view very few arguments for buying this product. Since the Nikon 1 V1 also hardly stands in the photo studio, the article is rather dispensable.
