The majority of the members in the Photo Club I belong to use the Better Beamer. Both price and function are the determining factors. We use the Better Beamer when we go photograph Hummingbirds in a canyon near Tucson. I suggest calling B & H or others that sell the Beamer to get the correct fit, that is what I had to do. Good Luck Doug **Q: will this fit on a NW680 Neewer** A: Measure the height of your flash head or refer to the flash manual for exact measurements. Then compare the measurement with the dimensions below to determine the right size Better Beamer flash extender for your setup.

Then I met a photographer at Balboa Lake, Ca. who was shooting with a Better Beamer. He let me try it with my equipment - - - then I ditched my homemade version and bought one. I have found that it is effective with my setup to about 100 feet. Beyond that a little iffy. The ability to fold it flat is a strong plus. It is not indestructible, but with care it should last a long time. Here is a photo I shot at the L.A. River Narrows, Glendale, Ca. You can see the area covered by the Beamer. The specs on this shot are: f/6.3@1/2000, ISO 800, Sigma 150 - 500 @ 400 mm, Nikon SB-800.. ### ⭐⭐⭐⭐⭐ The Beamer is a better way. *by A***R on August 11, 2014* I use the Better Beamer ('Beamer') for small bird photography in low light and high contrast conditions such as against bright skies. It is intended for use with external flashes and telephoto lenses of 300 mm or greater focal lengths. The Beamer can easily make the difference between getting the shot at 40-50 feet or not at all because it focuses the external flash's normal output so that it effectively reaches further while at the same time reducing the TTL's measured light requirement. It is light in weight and one has to be careful to keep the fresnel lens pointed away from the sun to avoid burning either equipment or surrounding area. It can put enough light on the bird to easily create a catch-light effect but if the Beamer is mounted too close to the optical axis of the lens it produces "steely eyes". That is, the bird's eye appears to have a large white spot instead of a small catch light of reflected sun (flash) light. To avoid this requires a bracket to move the flash up and away from the lens axis but this simply demonstrates the power of the Beamer to get the light you need out to the bird. With the Beamer on an external flash mounted on a bracket to move the flash off the optical axis of a large telephoto you've got a serious looking and slightly cumbersome rig but that's what it takes to get shots of small, frequently jittery birds in the wild. Get a Beamer and you'll be amazed. ### ⭐⭐ I have trouble lining up the flash beam to the ... *by L***L on August 22, 2015* I have trouble lining up the flash beam to the subject. Took some test photos the main beam of the flash was either to high of to low to the target area. Takes a lot of time to get it right, which you don't have when photographing wildlife. It is flimsy don't know how you would use it in windy conditions. Its $35+ for a piece of plastic. ## Frequently Bought Together - The Flash X-Tender (Better Beamer) FX-4 Flash Output Booster for the Nikon SB-600 and SB-800 Flashes with Lenses 300mm - SanDisk 128GB Extreme PRO CFexpress Card Type B - SDCFE-128G-GN4NN, Silver - Nikon EN-EL15c Rechargeable Li-ion Battery for Compatible DSLR and Mirrorless Cameras (Genuine Accessory) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/1201192-the-flash-x-tender-better-beamer-fx-4-flash-output](https://www.desertcart.ph/products/1201192-the-flash-x-tender-better-beamer-fx-4-flash-output) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-23*
