CN-E135MM T2.2L F
- Compact 135mm, T2.2 prime lens.
- Spectacular 4K image quality.
- Full frame image circle.
- Industry standard manual control.
- 11-blade diaphragm for attractive blurring.
- Designed for EF mount 35mm and Super 35mm cameras.
EF LENS MOUNT COMPATIBILITY
The CN-E135mm T2.2L F lens is designed for use with EF mount cameras with either full frame 35mm or Super 35mm-type sensors – perfect for Cinema EOS cameras as well as Canon's range of EOS DSLRs. Contacts on the EF mount facilitate communication between camera and lens for recording of metadata, and other functions.
OUTSTANDING OPTICAL PERFORMANCE
The lens delivers exceptional 4K (4096x2160 pixels, compared to the 1920x1080 pixel count of Full HD), optical performance and offers compatibility with Super 35mm-equivalent cameras, full-frame, APS-C and APS-H cameras.
Employing anomalous dispersion glass that's effective in reducing chromatic aberration, plus large-diameter aspherical lenses, the lens achieves high-resolution imaging from the centre of the frame to the outer edges.
CINEMA USER-FRIENDLY HANDLING & FOCUS/IRIS CONTROL
The CN-E135mm T2.2L F lens offers a sturdy build that’s user-friendly for demanding productions. It features focus and iris markings that are engraved on angled surfaces for improved readability from behind the camera.
Featuring the distinctive ‘resistance’ of cine lenses the lens offers outstanding manual control. The lens offers a focus rotation of approximately 300 degrees and facilitates precise focusing performance.
An aperture diaphragm with 11 leaves creates gentle, attractive blurring for cinematographic effects.
This prime lens can be used with standard manual and electronic movie industry accessories, and other equipment such as matte boxes. Featuring a unified front lens diameter and uniform gear positions, this enables film crews to quickly change lenses without adjusting rig setups.
ANOMALOUS DISPERSION GLASS
To reduce chromatic aberration the CN-E135mm T2.2L F prime lens employs anomalous dispersion (AD) glass. When light passes through a lens, it refracts (bends). It also breaks up into its constituent colours, just like light passing through a prism. The lower the refractive index of the lens material, the less it bends and the sharper it can be focused. Similarly, the lower the dispersion ratio, the less the light is broken up, which makes it easier to correct chromatic aberration.
AD glass is similar to fluorite in that it features a low refractive index and low dispersion. Using AD glass Canon has been able to manufacture lenses with superior performance at a lower cost.
LARGE ASPHERICAL LENSES
Within the optical construction of the lens, large aspherical elements are deployed to reduce distortion and deliver unrivalled optical performance. In the early days, all lenses were spherical – they are the easiest lens shape to make, but are not best suited to rendering a sharp image as they cannot make parallel rays of light converge at the same point. This causes a problem called spherical aberration. Canon designers discovered that an aspherical (non-spherical) lens shape would eliminate these spherical aberrations, because the curvature of the lens could be used to converge the light rays to a single point.
