35mm Cine Lenses vs. Stills Lenses
35mm motion imagery has been captured using PL-mount Cine lenses for decades. They are the standard of motion picture production. These lenses are designed with the highest quality, most efficient acquisition for Cine style shooting. It is for this reason that SSV offers Super 35mm digital Cine cameras with the PL-mount rather than still photo lens mounts and stills lenses.
Advantages of PL-mount Cine Lenses:
PL-mount stands for "Positive Lock", the most rigid, exacting and rugged lens mount available for digital Cine cameras. This is important for precise flange distance on sharp lenses, support of heavy lenses and eliminating frame movement due to torque exerted by follow focus systems and zoom motors.
PL-mount cameras can take advantage of any Cine lens built in the past 30 years, the lenses that Hollywood depends on everyday.
Cine lenses offer the highest quality available, are much more rugged and reliable than stills lenses. They are built especially for the image quality and rigors demanded by professional Cinematographers.
Cine lenses have fully manual, de-clicked, numbered iris rings for precise exposure setting and on the fly exposure changes, unlike most modern stills lenses. They also have gears for remote activation. Cine lenses often feature more iris blades for a more pleasing, circular "bokeh" when specular highlights are out of focus. These lenses are typically optimized for good sharpness and contrast when wide open.
Cine zoom lenses are Parfocal, meaning that when zoomed, they track focus, unlike many stills lenses that require refocusing every time focal length is changed. They feature smooth, dampened manual operation and precise markings on both sides of the lens(for operator and Assistant Camera) with gears for precision zoom motors. They usually feature constant aperture throughout the zoom range vs. low cost stills lenses that "ramp" downward in light transmission when zooming in. They typically have less chromatic aberration or soft corners than low cost stills lenses.
Cine lenses often have much greater focus rotation(throw) for much more precise, repeatable focus pulling. A typical stills lens has a focus rotation of around 100 degrees, whereas a Cine lens is often over 300 degrees. The focus barrels have calibrated distance marks on both sides of the lens. They are geared so that follow focus systems can be used. Cine lenses are less likely to "breathe" while focusing. They are not optimized for auto focus, found on modern stills lenses, where manual focus is an after thought, and barely turning the focus barrel changes the focus setting significantly.
SSV offers full Cine lens focal length coverage from 11mm to 200mm with speeds of T1.5 to T3.0. Most of our Cine lenses rent for no more than a typical good quality stills lens(we offer some rehoused stills lenses that are modified in the above ways for Cine housings). Cine Support accessories include Arri, Elements base plates and rods, 12" dove tails, Arri, Chrosziel matte boxes and Arri, Zacuto follow focus systems for ultimate support and control of Cine style shooting.

New HD Gear Keeps Coming!
2012 brings new gear to SSV. While we have over the past few years become more involved with film style camera packages and accessories--such as our Panasonic AF100 large sensor digital cine cameras, Arri Alura 35mm Cine zoom and Nikon 35mm SLR prime lenses, and camera support--we are investing more into multi-camera HD equipment.
We have just completed an HD Fly Pack featuring the new Panasonic HS410 production switcher. This system can be used with any camera, and offers a very small foot print and affordable rental rate combined with an amazing amount of power and flexibility for signal distribution, transcoding, scaling and routing.
The Panasonic HS410 HD switcher has 13 inputs, including SDI, HD-SDI, DVI(digital and analog) and 5 HD-SDI outputs, plus component and 2 DVI outputs which are scalable to various computer resolutions. The HS410 has a multi-viewer, a built-in 7" LCD display for menus, images and scopes, 4 auxiliary buses, and many advanced features previously not seen at the price point. This switcher is available separately with multi-viewer display or with our new HD Fly Pack. We offer various camera/CCU options, and recording options, such as AJA Ki Pro ProRes decks.
Also new at SSV is the Panasonic HPX250 P2 full raster HD camera that brings a 10-bit, 100Mbps, 4:2:2, I-Frame codec to a palmcorder form factor for the first time with AVC-Intra 100, the same recording format found in our HPX2700 P2 Varicam HD camera. The HPX250 excels at green screen work and heavy grading, color correction.
We also have several high quality HD LCD production monitors/scopes by Flanders Scientific, Leader, Panasonic and TV Logic, ranging from 5.6" to 21" to compliment our cameras and HD fly pack.
Finally, in addition to our Analog Way Di-VentiX 2-channel HD seamless switcher/scaler, which is great for projection and flat panel display switching, we've added an Analog Way Pulse 300 2-channel HD seamless switcher/scaler, offering many of the same features of the Di-VentiX at a lower cost. Either of these units compliment our new HD fly pack for live production nicely.
We plan to add a new Super 35mm Digital Cine camera very soon, because we remain committed to film style production with its cinematic imagery. This means SSV will have cameras with 1/3", 1/2", 2/3", micro 4/3" and Super 35mm sensors and several recording format options to choose from. We're happy to help figure out how to apply these options to best suit your specific project--contact us anytime!
