oh, really?
And how do we know that?
By searching this forum, and several other outdoor forums in which professionals and amateurs alike have done personal, side by side viewing and comparing. I've done it myself with my own trinovid, a SLC, and an EL. The view is better in my 10x Zen ED2 than my own 10x trinovid, my neighbors 10x SLC, and I cannot tell much of any difference in it and my neighbor's 10x EL. That's how I know, personal use. How do you know they're not? (No I don't work for, nor paid by ZR)
