The OMNI™ 18-inch Reflector is a multi-purpose modifier system for all shooting styles, fitting on the faceplate of all standard BUFF™ flash units (including standard AlienBees™ units, Einstein™ units, both current and retired White Lightning™ units, and the retired standard Zeus™ units).

DIRECT COVERAGE

Using the OMNI™ reflector directly (without the included diffusion sock) produces very even 30° coverage with smooth feathering. Its extreme output is ideal for overpowering the sun and for sports and other uses requiring long light-to-subject distances - f8 achievable at 56’, ISO200 for gymnasiums, etc. For girl-on-the-beach shots, light placement of 14’ to 20’ eliminates the unnatural look and wind-prone nature of softboxes and umbrellas, yet still allows f16 to f22 exposure at ISO100, 640WS. This configuration is additionally useful for high-key shooting in the studio and on location, from a modestly large, punchy light-source.

ADDING THE TRIPLE LAYER DIFFUSION SOCK (included with the OMNI18R)

Adding the 3-layer diffusion sock to the reflector (fitting over the outside lip) creates exceedingly even 120° coverage and manageable exposure levels, making this the perfect choice for high-key, mid-key, and group lighting - your go-to studio modifier. The 18” diameter is considered ideal by many pros for sweet-spot contrast, specularity and shadow control. Relatively low output and buttery-smooth coverage make this configuration ideal for beauty-dish style, close-in lighting where f4 is achieved at 30” (5WS, ISO100). We suggest using the OMNI™ with the included diffuser in place of beauty dishes or softboxes for many shooters. For even more control and 6/10f lower output, the optional 20° honeycomb grid spot (sold separately - coming soon) can be used with the included sock.

ADDING THE 20º GRID (NOT included with the OMNI18R - sold separately - coming soon)

Coming soon - an optional 20º grid for the OMNI™ reflector (sold separately) that can be used directly on the reflector, with or without the diffusion sock in place. The grid snaps into the recessed outer lip of the reflector alone or on top of the diffusion sock. When used directly on the OMNI™ reflector, the grid and reflector are ideal for high output, Hollywood-style selective lighting with superior spill control and isolation. For close-in mood lighting, place the grid over the triple layer diffuser to further reduce the output and achieve high fall-off, high contrast low key lighting effects. The grid reduces the light output another 2/3f stop, allowing even closer placement at wide-open apertures without the “dark center” that is typical with beauty dishes.

FACE VIEW WITH THE DIFFUSION SOCK (included with the OMNI18R)

The OMNI™ reflector is designed so that the light rays strike the surface of the triple layer diffuser evenly - from center to edges. This detail is ignored in most other reflectors. The result is a degree of evenness across the diffuser face unrivalled by the best softboxes or beauty dishes. This yields an extremely even, perfectly round light-source for great catchlights and beautiful rendering of reflective objects such as silverware, vases, etc. High diffusion reduces light output to allow low depth-of-field shooting with close light-to-subject distances. Adding the optional 20° honeycomb grid (sold separately) over the diffuser further reduces output and eliminates spill light for even closer lighting, enhanced mood and soft/selective lighting.

The reflector is not compatible with the AlienBees™ ABR800 Ringflash, the retired Zeus™ Ringmaster head, or the retired WL Series™ (5,000 and 10,000) units.

Honeycomb Grids: Coming Soon! The optional OMNIGRID20 20º Honeycomb Grid is designed for use with the OMNI18R and can be used with or without the diffusion sock in place. Other grids will NOT fit the OMNI18R.

Carrying Bag: For around town travel, the HOBD-BAG 22-inch carrying bag can be used to carry one OMNI reflector. The bag additionally includes a zippered compartment to hold a grid (once these are available).
