The one thing about the ART system is it tells you what reticle mark to hold on for increments of 25 yards Does the BRH system work similar?
Yes, it does. See my post in your other thread about ART reticles.
I've been evaluating Z5 scopes recently and have already reached a few conclusions. I will probably post a review at some time. Here are some of my notes.
What sets Z5 scopes apart from other high magnification ratio scopes is their outstanding optical design. The objective is a triplet (three lenses) instead of the more common doublet. The triplet gives the scope better correction of chromatic aberration so that color separation is nearly nonexistent. The triplet also reduces off-axis aberrations so that the image remains crisp and clear at the most extreme elevation/windage settings. By comparison, a doublet begins to lose resolution when the elevation/windage adjustment exceeds about 20 MOA.
The internal surfaces of the scope have a stepped microtexture surface that is coated with an ultra-low reflectivity black material. Stray light is suppressed so well that glare is almost undetectable, creating an exceptionally high contrast image.
The Z5 erector tube optics are derived from the truly excellent Z6 models. The high resolution, low glare and high contrast produce a bright, clear image across the field of view. The field is flatter than competing scopes in this class. The contrast and resolution are so good at high magnification that these scopes can be used as spotters in the field. Unlike many high-zoom ratio scopes, the Z5 models do not exhibit tunneling at low magnification. That is, the field of view continues to increase as the magnification decreases all the way to the lower limit.
The sight picture is clean at all magnification settings, with no vignetting at any combination of magnification and elevation/windage setting. A large exit pupil diameter of about 10 mm at the lowest magnification setting enables rapid target acquisition.
