This is a special reverse version of the DSLR Hotshoe adapter. The slot for a finder mount is on the front side instead of the rear.

This a Vixen Style Finder Dovetail Bracket for hot shoes on DSLR or older SLR cameras. Our solar finder can be mounted directly on it or you can directly mount small guide scopes or finders. Made from all-aluminum construction. Also has a 1/4-20 threaded hole on the bottom for mounting on tripods, ball heads, or any other standard camera mounting. Is compatible with GSO, TPO, Vixen, X-class, Zhumell, etc.

The fourth-generation hot-shoe adapter comes with a D shaped central pillar to prevent loosening or movement.  We have also added a second thumbscrew. This allows better lockdown, but also gives you the choice to use a right or left thumbscrew if either is in the way.

This adapter is for Vixen style FINDER dovetails, not for telescope mounts.

Fitting tips: For a new camera hotshoe, use both thumbs to push DSLR adapter into the hotshoe, then tighten down the ring. If there is any side to side movement at the interface between the adapter and your hotshoe, a simple toothpick into the side of the hotshoe will eliminate this movement.

This hot shoe adapter has another great function. It has a 1/4-20 mounting hole in the center, so you can turn your camera tripod or anything with a 1/4-20 screw into a finderscope mount.

Not compatible with Sony proprietary hotshoes, like on the Sony A700.
