Building upon the foundation laid by their S-series, Maven’s S1.2 spotting scopes incorporate new features and options that make them very competitive.


Maven optics wasn’t taking any chances with clarity on these optics.  It’s obvious they had the discerning end-user in mind.   The lenses are fully-multi coated and phase corrected.  The S1.2 also uses fluorite glass lenses.  Fluorite is a crystallized form of calcium fluoride first used in microscope lenses, where it was found to reduce chromatic aberration to extremely low levels. Chromatic aberration occurs when light passes through a glass surface due to various wavelengths of light being refracted at different angles. This makes the red, green, blue, etc… light converge at different focal points which causes color “fringing” where high contrast areas show blue or purple tints on one side and green or yellow tints on the other.  At high magnifications, this can make the total image look generally hazy and color definition is lost.  Fluorite lenses have much lower dispersion which significantly reduces this effect.  The end result is a razor-sharp image with excellent color definition.


One of the key features of the S1.2 is the interchangeable eyepiece.  Users can switch from a 25-50X zoom lens to a fixed 30X Milliradian or MOA reticle eyepiece in seconds. Having a reticle reference in the spotting scope enables quick, accurate adjustment calls to shooters, getting them on target faster.  Being able to swap out to a zoom-lens without a reticle is great for wildlife, scenery, or even some astronomical observation.

The S1.2 also integrates an Arca-Swiss foot which adapts to any tripod head that accepts this universal quick-release mount system.

An integrated lens shade is incorporated to minimize lens flare, particularly in high-contrast lighting conditions common with mid-day sunlight. 

The model we received for evaluation is the angled version, but a straight version is available based on preference. The angled model features a side tripod collar adjustment knob, enabling precise rotation along the X axis to align with the tripod angle and viewing preferences.

One of the benefits of the direct to consumer model is savings.  The nearest competitor in terms of features and performance has a price point roughly $1400 higher.  The S1.2 is a few ounces heavier, but an inch shorter. It has slightly less field of view at the highest magnification, but a little better field of view at low magnification.   Are those margins worth the extra price tag offered by the big-name competitor?  My personal opinion is no.  I think Maven walks away with the win here in terms of performance vs. price.

With this optic, Maven is proving their commitment to quality and features that the end-user wants.  There is an emphasis on optical clarity and toughness for a professional-grade optic that will put up with harsh field conditions.
