This Sigma FF High Speed 7 Prime Lens Kit with Case includes 7 full-frame Canon PL mount cinema lenses in 14mm, 20mm, 24mm, 35mm, 50mm, 85mm, and 135mm focal lengths . The 20mm through 85mm open up to a bright T1.5 while the 14mm and 135mm open to T2. Similar physical properties between the lenses in this set allow for quick lens changes in the field. Lens markings in luminous paint against the black finish help to clearly identify focus and iris position in dim conditions.
