Designed for the digital cinema market, the Leitz Cine 18mm T2.0 Summicron-C Lens PL Mount Feet(C for cinema) features a stainless steel PL mount and provides a smaller, lighter, albeit slower option to the renowned Summilux-C series of lenses. The 18mm focal length is a common choice for a wide angle lens in the Super 35 format as it provides a strong wide-angle effect without extreme distortion. The small size of the lens makes it suitable not only for regular production but also for stabilized rigs, aerial cinematography, and stereoscopic 3D capture. Projecting a useable image circle of 36mm in diameter, it is compatible with a variety of cameras that have sensors that are slightly larger than Super 35. The T2.0 maximum aperture is consistent among the range, so there is no concern about exposure variations when cutting between Summicron-C lenses. Each lens incorporates geared focus and iris control rings, which share the same position, so swapping lenses can be done without having to adjust your follow focus or lens control system.

The lens features an internal focus design, which means a non-rotating front perfect for clip-on matte boxes. A generous number of focus marks are distributed along the dual focus scales, and the 300° of focus rotation provides for accurate focus pulling. The 95mm diameter front is standard across all Summicron-C lenses, and, except for the 15mm and 135mm, they feature similar weight and the same length.

The Summicron-C lenses have an image circle of 36mm, which is more than generous enough to cover the sensors of many popular cameras, including the 6K Red Dragon Sensor, without vignetting. For reference, the image circle requirement for Super 35 is approximately 28mm.

The lens is telecentric, which helps reduce illumination fall-off from light hitting the sensor at a sever angle outside of the image circle.

The modern lens design as well as the cine manufacturing process and tight tolerances ensure low distortion, high resolution and excellent color rendition. Although made using spherical elements only, the Summicron-C lenses provide a sharp image with a naturalistic Bokeh.

The 300° of focus rotation provide for extremely accurate focus marks and focus pulls.

Consistent front diameter and shared focus and iris ring position from lens-to-lens in the series allow for faster lens changes requiring less adjustment of matte boxes and lens accessories.

Q: 1. What is the minimum focusing distance of this lens?

A: SLR Magic does not list a minimum focusing distance for this lens. However they do list a Closest Focusing Distance of 0.66' / 0.2m for other models of 18mm lenses that they have. It should be in the same range with this model as well.

Q: 2. Can you have both the full frame adapter and the anamorphic adapter on this lens at the same time?

A: No you cannot.

Q: 3. Hi there, what are the 6 screws for that come in a pouch with the lens?

A: The Screws are for focus assistance and would give you more of a grip to control the 7artisans Photoelectric 50mm in a more easy fashion giving you something to hold onto. Also the package does not include a pouch.

Q: 4. What focal length it will become when shouting in a crop mode, like 4k60 on S1?

A: In Super35 mode, the Viltrox 20mm will be more like a 30mm.

Q: 5. Could this cover the s35 sensor of the z cam s6 w/ MFT mount?

A: No, it will not. Although this will mount on the MFT mount, it will only cover an MFT sensor. It would be suited for a Blackmagic Design Pocket Cinema 4K.

Q: 6. what is the focal length on a bmpcc?

A: The original Pocket Cinema Camera has a 2.88x crop factor which will make this lens the equivalent of a 51.84mm. While the Pocket Cinema Camera 4K has a 1.9x crop factor for a 34.2mm field of view.

Q: 7. Does this include lens support? If not, is it fit screw size with ARRI Lens Support LS-9?

A: There is a lens support stud/foot on the bottom of the lens that will mate with any industry standard 15mm/19mm rod support system.

Q: 8. Does this lens work with speed boosters like the Metabones Ultra?

A: It will not. This lens only covers up to an APS-C or Super35 Sensor and Speed Boosters require a full frame lens.

Q: 9. Since this says it covers a super35 sensor, is it 25-100mm on a super35 or would there still be a crop factor of ~1.5x (Making it 37.5-150mm)?

A: Yes, The native crop of a S35 sensor is about 1.5x. The view of the Venus Optics Laowa OOOM 25-100mm T2.9 Cine Lens would be 37-150mm.

Q: 10. Will Tilta Mirage Matte Box fit on this lens?

A: No, the Venus Optics Laowa OOOM 25-100mm T2.9 Cine Lens (PL Mount, Feet) has a 100mm front diameter and the Tilta Mirage will clamp onto lenses with up to 95mm front diameter at maximum.
