This lens may seem big and heavy until you realize it’s equivalent to a 80-300mm lens on full frame. With the included teleconverter you your reach extends to 210mm or 420mm FF equivalent (only works with this lens! attempt to mount on other lenses will damage it!). With a long lens like this you can separate your subject from the background with ease, or you can compress distance to create almost surreal compositions. Great for tight headshots.
This lens is always mounted on one of our cameras when we record live shows or seminars. Do note that doing video with such long focal lengths requires a good video tripod and head, such as the Sacthler FSB-8.
