Tom Calton had the unique chance to play with the massive Sigma 200-500mm f/2.8 lens (listed here at BH). Tom writes:
For some reason Sigma were happy to lend me their colossal 200-500mm f/2.8 BAZOOKA lens for a day. This thing is HUGE – it weighs 15.7kg (553.7oz) and costs £15,000.
This lens also comes with a 2x teleconverter which jacks it up to a 400-1000mm f/5.6 lens. Shoot with this thing on a crop sensor camera and you can get an equivalent focal length of up to 1600mm! To see what that looks like, check out the full video below.
