Their cinematography primes are not bettered by anyone in any department. Other optical companies with innovative optical histories like Nikon and Canon can do it. The Canon 10x42 L first came out in 2003 and the point of focus is the same at the edge as at the centre. Astigmatism is very low. Rolling ball is eliminated with traditional levels of pincushion distortion off-axis.     Using the Allbinos scoring methodology the Noctivid is not going to topple the Nikon EDG 10x42 off the first place ranking !<a href="https://www.allbinos.com/215-binoculars_review-Nikon_10x42_EDG.html" target="_blank">https://www.allbinos.com/215-binoculars_review-Nikon_10x42_EDG.html</a>Looking at the low element count the EDG must be using expensive glass aspherical elements to control spherical aberration. Imagine what would happen if Nikon updated the design with fluorite glass which their  Akita plant (Hikari Glass Co.Ltd.) now make for the lens division. You would have an instrument with perfect baffling, sparkling view, no aberrations, distortions or focus anomalies. Game over.BTW. Does Roger Vine post in this forum ?</blockquote>
