The Canon CN-E 135 mm T2.2 L F Cinema Prime Lens (EF Mount) is a nifty accessory that is capable of shooting impressive photos and 4K-quality footage from any Canon EOS cinema or DSLR camera with an EF mount. The lens features an 11-blade iris aperture diaphragm, which delivers a beautiful bokeh for the background of your subject. The markings on the barrel’s angled surfaces on both sides allow you to read settings from behind or from either side. You can switch the focus markings from standard labeling to the metric system to ensure a versatile shooting experience. The glass construction of this lens prevents temperature-induced marking discrepancies. The control rings are designed in such a way that you can always maintain a consistent operating torque. Also, the lens’ 114-mm front diameter is similar to that of other CN-E lenses.
This is the size of a front lens cap. Standard sizes for snap-on lens caps include: 27mm, 28mm, 30mm, 34mm, 37mm, 39mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm and 86mm.
