The S1 AC/DC 500Ws HSS TTL Pro 2-Light Kit for Sony was put together by B&H to offer total wireless freedom from power and PC cords plus TTL exposure to photographers who work on locations without an immediate source of electrical power. The kit includes 2 Interfit S1 AC/DC 500Ws HSS TTL monolights and a TTL transmitter for Sony with an operational range of 300', and two 10' air-cushioned light stands are included to support them. Light modifiers include a Luxbanx 36" Octagonal Softbox and a Luxbanx 15 x 55" Strip Softbox, both with speed rings. It all fits in the kit's padded carrying case.

  • 2 x Interfit S1 500Ws HSS TTL Battery-Powered Monolight

    With the introduction of the S1 500Ws HSS TTL Battery-Powered Monolight, Interfit joins the small group of manufacturers producing TTL monolights. The flash head is powered by an internal, removable 4500mAh lithium-ion battery that fits inside the head's housing. It has a 350 full-power flash capacity and can also run on AC while your battery is charging. It's controllable wirelessly at distances up to 328'.

    The S1 has 3 shooting modes: Wireless TTL for Canon, Nikon, or Sony; Manual Mode; and High-Speed Sync. Wireless requires purchase of a Nikon, Canon or Sony dedicated transmitter, but once that's done, you can basically treat these studio strobe units as you would your on-camera flash. In TTL, the camera's flash technology takes stock of the scene and automatically adjusts the power from 7.8 to 500Ws across a 7-stop range. If you want to fine tune your exposure, there's +/- 3 stops exposure compensation adjustable in 1/3 stops.

    Traditional manual mode is available for those who want complete control. Manual mode is also how you access HSS (High-Speed Sync). This mode uses the flash's top 4 power levels (from 62.5 to 500Ws) to allow you to access sync speeds as short as 1/8000. HSS presents a new world of exposure possibilities whether you're trying to overpower the sun, control the background's brightness, or use wider apertures.

    The S1 recycles to full power in 3 seconds and a fraction of that time at reduced power levels. Thanks to the incorporation of IGBT technology, the flash can also reach flash durations as short as 1/9000 sec for the ultimate in stop-action while still maintaining a steady 5700K color temperature.

    The S1 ships as a complete system including a 350-shot Li-ion battery with a charger that powers it up in about 3 hours. Since the S1 is AC/DC, it can also be plugged into a wall outlet for use regardless of its voltage while the battery is charging. The S1 also includes a 7" Bowens S-Type reflector, an AD adapter and a mini USB cable.

    Complete Package
    500Ws monolight with High-Speed Sync, TTL for Canon and Nikon, IGBT technology, lithium-ion battery, and multi-voltage AC power pack in one complete package
    S1 TTL Remote
    The S1's TTL remotes give the users direct control over any S1 light in any shooting mode from the camera position. This camera-mounted transmitter is available for both Canon, Nikon and Sony cameras. Having three individual groups gives users the freedom to control lights individually to create dynamic lighting ratios with a working range of up to 300' (100 m)
    Power Supply
    Each Interfit S1 comes standard with both battery and AC-power sources. The interchangeable 4500mAh Li-ion battery provides up to 350 full power flashes in Manual and TTL modes and over 400 full-power flashes in High-Speed Sync mode. This wire-free power source gives photographers the freedom and mobility to venture out from the studio and rapidly set up and reposition lights on location. For traditional studio work, the S1 also ships with an AC power pack (adapter). This multi-voltage (100-240V) adapter can be used anywhere in the world and lets photographers continue to shoot while their battery is charging
    Shooting Modes
    The S1 has three different shooting modes, each to serve a different purpose and shooting style. Interfit's S1 Remote for Canon, Nikon or Sony enables photographers to take advantage of their camera's TTL system just like they would with a speedlight. This automated light output uses the S1's entire 7-stop power range (500W - 7.8Ws), is automatically calculated in 1/10th stop increments, and allows for +/- 3 stops of exposure compensation
    Manual Mode and High-Speed Sync
    For those that prefer to have complete control of their light and have time for fine-tuned adjustments, the S1 can be used in the traditional manual mode. Manual shooting mode also utilizes the entire 7-stop power range, controllable in 1/10th stop increments. While in manual mode, users can access the S1's High Speed Sync mode, reaching shutter speeds up to 1/8000th of a second. High-Speed Sync mode utilizes the top 4 stops in the power range (500 - 62.5Ws) and is manually adjustable in 1/3-stop increments
    IGBT
    Utilizing IGBT technology, the S1 is able to offer short flash durations while maintaining color accuracy throughout the power range. Flash duration ranges from 1/1000 at full power, to 1/9000 at minimum power. While shortening the flash duration, Interfit was also able to improve color accuracy, giving the S1 a consistent 5700K (+/-100K) color temperature throughout the entire power range
  • Interfit S1 TTL Remote for Sony

    Dedicated to the Interfit S1-series of monolights, this S1 TTL Remote permits wireless TTL control over the light when working with Sony cameras. It supports the Sony P-TTL protocol and permits working with three distinct groups (A,B, and C) for creative flexibility and greater control over lighting ratios. The remote is designed to be mounted via the camera's hot shoe and enables control over the S1 monolights from up to 300' away. Users will appreciate features such as control of audible recycle beep and LED modeling lamp, and sync speeds up to 1/8000 second.

    Firmware Requirements
    May require updating the firmware of your S1 light
    Power Adjustments
    Allows for precise power adjustment in Manual, TTL and High-Speed Sync modes

  • Impact Luxbanx Medium Strip Softbox (16 x 55")

    The Luxbanx Medium Strip Softbox from Impact is a light shaper with a high degree of directional control thanks to its long narrow form factor. Designed to illuminate a "strip" of the subject as compared to other modifiers, this 16x55" size softbox is ideal for fitting into tight spaces with low ceilings. It's often used to photograph large products or in full length portraiture to edge light the subject, and it's a good choice for hairlighting large groups and lighting cycs and backgrounds. This size is also often used to provide highlights in car and motorcycle photography.

    This Luxbanx softbox features a soft white interior, removable front diffuser and removable inner baffle. The diffuser and baffle can be used together for maximum softening of the output. Removing the inner baffle will give you a more crisp light quality with higher contrast, while shedding the front and inner diffusers turns the Luxbanx into a large reflector with maximum brightness and contrast.

    The versatile Luxbanx has an additional control via the optional fabric grid which mounts to the recessed lip of the softbox with touch-fasteners. The grid narrows and concentrates the light's beam forward, controlling spill and adding directional control to the Luxbanx's attributes. The long, narrow shape of the softbox makes it ideal for side-lighting in portraiture, accenting cars and bikes and photographing glassware and other reflective objects. Every Luxbanx comes with a carrying case and a spare Flex Rod. Separate purchase of a speed ring that matches your strobe's mount is required for use. Impact makes models to fit most popular brands.

  • Impact Luxbanx Small Octagonal Softbox (36")

    The Luxbanx Small Octagonal Softbox from Impact is a highly versatile tool for strobes, LEDs, and fluorescents. This 36" diameter softbox is large enough to exhibit the wrap-around light quality that this octagonal shape is known for, yet small enough to use in tight spaces. The softbox features a soft white interior, removable front diffuser and removable inner baffle. The diffuser and baffle can be used together for maximum softening of the output. Removing the inner baffle will give you a more crisp light quality with higher contrast, while shedding the front and inner diffusers turns the Luxbanx into a large reflector with maximum brightness and contrast.

    The octa Luxbanx has an additional control via the optional fabric grid which mounts to the recessed lip of the softbox with touch-fasteners. The grid narrows and concentrates the light's beam forward, controlling spill and adding directional control to the Luxbanx's attributes. The large surface area of this octagonal-shaped softbox gives you a unique wrap-around quality of light that gains emphasis as you move it closer. Catchlights in the eyes of your subject are round and natural. Every Luxbanx comes with a carrying case and a spare Flex Rod. Separate purchase of a speed ring that matches your strobe's mount is required for use. Impact makes models to fit most popular brands.

  • 2 x Impact Speed Ring for Impact, Bowens S, Westcott

    The Speed Ring for Impact, Bowens S, Westcott from Impact features indexed flex rod holes that allow you to effortlessly mount any square, rectangular, strip or octagonal Luxbanx softbox to Impact, Bowens and Westcott flash heads. The ring will also fit most other brands of softbox. The sturdy all-metal ring rotates 360 degrees to facilitate orientation or to clear obstacles in tight quarters. It has 3/8"-16 taps on two sides to allow mounting directly to grip gear such as Impact's Swivel Umbrella Adapter, 3 Section Double Articulated Arm, Super Clamp, and more.

  • Impact Light Kit Bag #2 (34 x 13.5 x 12")

    The black Light Kit Bag #2 (34 x 13.5 x 12") from Impact makes transporting your lighting kit easy and secure. The bag is designed to hold three monolights along with their reflectors (such as Impact VC500LR), four stands, boom, umbrellas, cables and other support gear but can also be used to hold other lighting equipment instead. You'll have plenty of room to take along enough lighting gear for a portrait session - all packed in an organized and accessible way. A touch fastened divider tray separates the stands, boom and umbrellas from the lights preventing them from bumping together and causing scratches or damage. For additional smaller equipment such as cables and small accessories, there are three interior 10.5 x 8.0" zippered mesh pockets.

    The bag is made from soft, padded water-resistant nylon and contains six movable touch fastened interior dividers (6 large, 2 small) that will permit you to configure the bag to accommodate the gear you need that day. The Light Kit Bag is carried by its two 2" wide overlapping top carry handles that can easily be extended into dual shoulder straps. The contents are accessed via dual zippers that when placed together will accept a user-supplied lock. For even more protection, the bottom of the bag contains three rubber feet for when the bag is placed on the ground. And the bag folds down to a quarter of its height for convenient storage and easy setup. Whether for storage or transport, the Impact Light Kit Bag will serve both pro or amateur well.

    The soft padded carry case is designed to hold three monolights with reflectors, four light stands, umbrellas, cables and other accessories
