After months of hunting and waiting on the-bay, I finally bought a Vivitar Series 1 90mm f/2.5 macro lens — the Tokina build. This lens is called the “Bokina” for obvious reasons. Something spectacular happened in the optical design that resulted in very smooth out of focus backgrounds. Hence derives its nickname.
I bought mine in Nikon mount, which means it will work on all of my Nikons, be it a film or digital camera. I am going to enjoy working with this lens. It is a classic by numerous standards.
