Binocular tripod adapter: which one fits your binocular

When a tripod adapter earns its place

ZEISS says free-hand binoculars typically have 7 to 10x magnification. Celestron says a tripod is not required at 8x to 12x but becomes necessary at 15x and higher.

The British Astronomical Association puts the line at 10x: anything giving more than 10X magnification is difficult to hold and should be mounted. The RSPB says 8x or 10x is the best compromise for birdwatching, and that stronger binoculars are hard to hold steady without a tripod.

Audubon explains why. Binoculars that magnify an image eight times also magnify the small movements of your hand eight times. If you own a 15x56 or an 18x56, an adapter is part of the kit. See when binoculars need a tripod for the full case.

Check whether your binocular takes an adapter

Of the models in the catalog, 259 carry a printed answer on tripod mounting, and 237 of those are tripod-adaptable. The rest give no thread or socket for an adapter to use.

Vortex states that its adapter fits tripod-adaptable binoculars and tripods with a 1/4"-20 socket or thread. That wording is typical: the adapter bolts to the binocular, and the tripod head takes the 1/4"-20 thread.

Nikon says a tripod is effective for long observation or at high magnification, and it offers adapters for that purpose. Use the binocular finder to narrow the catalog before you buy a mount.

Adapters by maker

Vortex sells two. The Sport Binocular Adapter uses a quick-release connector, and its slim profile lets it fit between the barrels of the largest high-powered binoculars. The Pro Binocular Adapter is a two-part system with a 1/4"-20 socket and thread. Both appear on the Vortex brand page.

Nikon prints four adapters, each tied to named series. The TRA-2 fits the ACULON A211 series and 10x50CF WP. The TRA-3 covers the EDG, MONARCH HG, M7, M5 and 5 lines, the PROSTAFF 7S and 7, and the Action series. The TRA-5 and TRA-6 serve the large 7x50 and 10x70 IF models and the 18x70IF WP WF. Nikon does not state the mount type. See Nikon binoculars.

Swarovski Optik offers the UTAs universal adapter, which is Arca-Swiss compatible and fits the whole EL family, the EL Range, NL Pure (except NL Pure 10x52) and the SLC 42. The TAs-SLC has an integrated tripod plate and fits the SLC 42 and SLC 56. More on Swarovski Optik.

Zeiss lists two for conventional video and camera tripods. The Binofix fits all binocular models with a 30 mm or larger lens diameter. The 1/4" Tripod Adapter fits the SFL, Conquest HDX and Terra ED 42. See Zeiss binoculars.

Leupold, Celestron and Field Optics Research

Leupold lists three designs. The Binocular Tripod Adapter Tray uses a hook and loop strap, attaches to any tripod with a 1/4"-20 mount, and holds any size roof prism binocular. The Quick-Stem replaces the front pivot cap on the hinge with a universal stud, and its Arca-Swiss base has integrated 1/4-20 threads.

The Field Clamp grips Leupold's gridded, ergonomic body, so it suits that body only. Leupold's full range is on its brand page.

Celestron prints one Binocular Tripod Adapter that allows you to mount a porro or roof binocular to a tripod. It does not describe the mount. Its binoculars are listed under Celestron.

Field Optics Research makes the Rapid-Release GEN 2. It has a receiver nut with tool-less quick release, and the base offers Arca Swiss, Manfrotto 200PL and 1/4"-20 on the bottom. The maker prints no fit list.

Choosing between them

Start with the fit line. Swarovski Optik and Nikon name their models, so match your binocular to the list. Vortex, Leupold, Zeiss (Binofix) and Celestron describe fit in broad terms.

Then match the tripod. A 1/4"-20 thread suits most camera tripods, and an Arca-Swiss plate suits heads with that clamp. If you use stronger models such as 15x56 or 12x50, pair the adapter with a binocular harness for carrying between stops.
