A nearby plaque reads: “In memory of Benjamin F. DeFrancesco 1898-1993. As the flag flies freely, so do I.”
I took this with a Sony NEX 5N and 16mm f2.8 lens and its matched ultra wide angle converter. I recall that I used this combination, but it’s hard to be sure as the metadata provides only the focal length of 16mm with or without the converter. The converter makes the lens focal length 12mm (18mm 35mm equivalent), which is pretty wide. It distorts quite a bit and is pretty soft in the corners. It’s an inexpensive alternative if you have only an occasional use for an ultra wide lens, particularly if you already have the 16mm (otherwise you would have to buy it as this converter is designed to work only with this lens).
