Thank you Paul, Jim and Frank. No, it's not an F1 lens. I tend to use legacy glass on my Nex -- and so the exif data doesn't record the aperture correctly. This is just part of a very large bubble someone created on the beach. So-- it's bubble solution. If you look at the picture I posted in exhibition (and will probably be putting in pending) -- that's where this one was cropped from. ~Melanie
