The Nikon Monarch 7 series was launched in the middle of 2012. At first only two models were offered – the 8x42 and the 10x42. Both instruments are Schmidt-Pechan roof prism devices and their prisms are made of BaK-4 glass covered by both dielectric and phase-correction coatings.
handy casing; huge field of view; good transmission; well-corrected chromatic aberration; moderate astigmatism; sensibly corrected distortion; good whiteness rendering; high quality of prisms and coatings; clean and black inside the tubes
