Riton has recently introduced their new 5 Primal 15-45×60 Spotting Scope.

The 5 Primal comes in a nice, protective hard-case.  It features ED glass and an angled ocular lens for easy viewing in the prone position and less neck-strain. The body is nitrogen-filled and sealed to make it waterproof and fog-proof.


There is a little chromatic aberration visible at the edges, but it doesn’t interfere with a clear image of these mountains roughly 100 miles away.

.22-caliber bullet holes at 100 yards can just be made out with this optic. Notice the parallel lines from the joints between these backstop ties indicating a small amount of pincushion distortion.


Chromatic Aberration 4/5 Chromatic aberration (when high-contrast objects can be edged by blues and yellows) was more pronounced in this optic than some other Riton optics I have used.

Distortion 4/5 There is a little bit of pincushion distortion (straight lines at the edge of the optical field curve inwards slightly – you can see this slightly exaggerated by the camera in the magnified view of the railroad ties above).

Field of View 3.5/5 The field of view on this spotting scope is roughly 20%-35% smaller than similarly priced and powered competitors.

Weight 5/5 This spotting scope is almost a pound lighter-weight than similarly priced-and-powered competitors.


The main benefit of this optic over similarly priced-and-powered spotting scopes is its lighter weight. It is a functional, durable spotting scope in a useful power range.
