[1][2] The 70-200mm f/2.8 lens is popular among event photographers and photojournalists where the lower light capabilities are required.
Some portrait photographers also prefer this lens for the improved background blur produced by the f/2.8 aperture.
The lens showcases an off-white weather resistant plastic and metal exterior with a rubber focus and zoom ring.
It also features three external focus-hold buttons for locking in focus on a subject in motion.
When using the 1.4x and 2.0x teleconverters, image quality falls off overall but remains fairly sharp.
