Xtend-a-Sight™ Plus Red Dot Sight Mounting adapter
for connecting a Red Dot Sight to the flash shoe of your camera.

The Photosolve Xtend-a-Sight Plus is now in its third version. The Xtend-a-Sight allows you mount a Red Dot sight (typically found attached to rifles and pistols) to the flash shoe of your camera. This allows you to track moving objects much more accurately than the LCD or the viewfinder because the LCD generally "locks up" for a short while during processing of a picture and the viewfinder of a DSLR is "blanked" during the mirror up routine, or because of its limited view, it's difficult to keep a moving object in sight.

Xtend-a-Sight Plus
The redesigned Xtend-a-Sight Plus! Much quicker to mount and unmount, with no play in the shoe. Featuring 3/8 and 7/8 (sometimes seen listed as 5/8) Weaver mounts for Red Dot Sight mounts.


For reference: The shorter 3/8" mount rail is 1.6" long, and the overall length of the larger Weaver rail on the unit is 2.75".

Important Note: The Xtend-a-Sight is designed to work with a "standard" flash shoe...the type that's been around for a very long time. If you have an earlier model Sony camera that sports a proprietary type shoe used in Sony models introduced before 2012 (like the A100, A200, A250, A300, A350, A330, A380, A500, A550, or A700), you will need the Sony Adapter which is an optional add-on. When you shop, just select the adapter (under the name SHOEADAPT in the listing for the Xtend-a-Sight Plus) and when you click ADD TO CART, the adapter will be added as well ($3.95 additional).
Essentially, the Xtend-a-Sight is a modern "sports finder" and you can put the strap of the camera around your neck, push the camera out in front of you, with the strap tight to your neck, look through the Red Dot Sight optics at the object using the "red dot" that shows in the screen, half press for focus, and then take as many frames as your camera will allow as you follow the moving object.
If you don't have a flash shoe on your camera, you've still got a solution. Xtend-a-Sight shown with Daisy Red Dot Sight mounted (3/8" standard Weaver mounting) on the special "C" flash bracket. You can also mount it on a standard bracket
The all new locking foot, custom designed for the Xtend-a-Sight. While it is SIMILAR to a flash shoe mount, it's been designed to fit more closely into the flash shoe, so that when you adjust the knurled knob, the Xtend-a-Sight will lock in place with no unwanted movement of the Xtend-a-Sight.
Xtend-a-Sight Foot
IMPORTANT NOTE: This latest version of the Xtend-a-Sight Plus features a custom designed foot with a locking thumb wheel. This eliminates the previous hex wrench adjustment, and the potential up/down or side/side movement of the mount depending on the camera you have. We have determined that while most camera manufacturers agree on a standard flash shoe, they do not all follow the rules, and flash shoe width dimensions vary by several thousands of an inch. We've redesigned the locking wheel (it grabs the top of the shoe much more firmly), and trimmed back the foot so that you should not have the extra work. We haven't had any negative feedback from any of the hundreds of customers of of this new version, so we're hopeful that we've hit on just the right combination. If your particular camera still requires it, we're asking you, our customer, to carefully grind each side of the foot so that it will fit YOUR camera specifically. We apologize for the inconvenience, but we cannot control the manufacturing inconsistencies in the camera manufacturers, or their suppliers. A bit of wet/dry sandpaper placed on a flat surface. Press and carefully grind ONE side of the foot, checking periodically to ensure that you're not taking off too much.
Xtend-a-Sight shown with BSA RD30 mounted (7/8" standard Weaver mounting). This larger optical element size (30mm) of Red Dot Sight is a bit easier to see through, compared with the smaller sight shown below. However, this sight is typically 4 to 5 times as expensive as the smaller Daisy unit shown below

IMPORTANT NOTE: If you get one of these RDS units make CERTAIN that it comes with 7/8" mounting hardware. At least one unit (MADE IN CHINA) had 3/8" hardware and will NOT fit the Xtend-a-Sight as the spacing is too long between mounts.

Xtend-a-Sight shown with Daisy Red Dot Sight mounted (3/8" standard Weaver mounting). While this size of sight works just fine, it's a bit more difficult to use, given the smaller size of the viewing screen. The good news is that it's a lot less expensive.

Red Dot sights are available from numerous sources. The two shown here were purchased at WalMart, far below the regular retail pricing.

For the Amazon search box above, just put in "Red Dot Sight" (with the quotes).

In addition, many "paint-ball" outlets carry Red Dot Sights.

The only thing to remember is that the Xtend-a-Sight can mount 3/8" and 7/8" Weaver mounts (which are pretty typical), so get one with either of those two sizes.
