A FLASH BEAM TAILOR-MADE FOR MACRO
Most of the conventional wisdom surrounding underwater strobes is that brighter and wider always equals better. If you're shooting macro underwater photography, you want the exact opposite. You want a tightly controlled light to pinpoint the subject and keep the background as dark as possible. The Backscatter Mini Flash MF-2 is the perfect light + snoot combination for any serious underwater macro photographer. Its tiny size can get into the tightest spots and the companion Optical Snoot OS-1 makes it the perfect macro strobe to give you the creativity you've been missing.

STREAMLINE YOUR MACRO RIG—STROBE AND FOCUS LIGHT ALL IN ONE
If you’ve ever used a larger strobe made for wide-angle, you know it can be hard to get in tight spots, especially with dual strobes and managing a separate focus light as well. The small size of the Backscatter Mini Flash MF-1 makes it easy to manoeuvre and get into tight spaces. With powerful LED focus lights built-in, there’s no need for a separate focus light to manage on your rig. It makes a perfect companion for compact camera shooters looking for a great all-around streamlined strobe solution. It’s also the perfect solution for Advanced mirrorless and SLR shooters looking to reduce their footprint and simplify their lighting and lighten their rig for easier shooting.

THE EASIEST TO USE MACRO STROBE + SNOOT COMBINATION
Using a strobe with a snoot was once really difficult. Aiming a snoot took lots of practice. We designed the Mini Flash and Optical Snoot together with the purpose of making shooting with a snoot as easy as possible. With bright LED lights that project the same beam pattern as the flash through the snoot, you can easily see the exact placement of the snoot beam on your subject when framing a shot and know you are hitting your target. Have a critter that doesn’t like a constant light on all the time? Use our short duration modelling flash to check your snoot placement without continuously disturbing a light-sensitive critter.

The Optical Snoot OS-1 is easy to mount, with a simple click on/click off. The Optical Snoot OS-1 is small enough to keep in a pocket, allowing for a quick and easy switch from wide to macro.
