Been playing with the Vivitar 2x Teleconverter for 50mm lenses. Above shot was taken with my Mamiya Sekor 50mm 1:2 SX m42 mounted on the teleconverter. Using minimal lightning from a halogen lamp wich resides on my desk for light during the nighthours.
Editing is done using cameraraw 6.3 ps cs5 and silver efex.
