- Impressively fast f/1.4 maximum aperture affords control over depth of field and also greatly benefits low-light shooting, making this an ideal lens for astrophotography applications.
- Optical design includes ultra-low dispersion (UD) and Blue Spectrum Refractive Optics (BR) elements to reduce chromatic aberrations for impressive clarity and color accuracy.
- Air Sphere (ASC) and Subwavelength structure (SWC) coatings reduce flare and ghosting for improved contrast.
- Contrasting the ultra-wide field of view, this lens also excels with close-up subjects thanks to a 7.9″ minimum focusing distance and 0.19x maximum magnification.
- Rounded 11-blade diaphragm creates a smooth, rounded out-of-focus rendering.
- Manual aperture ring with de-click switch to make smooth, silent iris pulls.
- Focus breathing is especially well-controlled, helping to maintain a consistent composition and field of view when racking focus.
- Linear focus motor for intuitive manual focus control.
- Matched design with other Hybrid series primes; all lenses have the same 67mm front filter ring and general size for ease in rigging and working with multiple lenses on a shoot.
- Nano Ultrasonic Motor (USM) is used to control a floating focusing system while a Voice Coil Motor (VCM) adjusts a rear focusing group; together, these two systems offer an ideal mixture of speed and quiet performance that is especially beneficial to video recording.
- Floating focus design also helps to maintain consistent image quality throughout the focusing range, from 7.9″ to infinity.
- AF/MF switch and full-time manual focus override for intuitive focus control when needed.
- Effectively the same dimensions (3 x 3.9″) and weight (1.1 lb) as other Hybrid series prime lenses; these lenses also share a 67mm front filter ring diameter.
- Included filter holder attaches to the rear of the lens and accepts pre-cut gel filters; this is ideal for scenarios when more than one filter might be needed or if one filter will be used for a sustained amount of time.
- In addition to the manual aperture ring, this lens has a customizable Control Ring and Function Button, which can be programmed to control a range of shooting settings.
- L-Series level durability and weather resistance for working in inclement conditions.
