DC,
Are you sure the multicoatings are in view and not the lenses? That would be new information to me, but I don’t know that much, so I would not be too surprised.
Additional: If you are correct, don't think I am challenging that. I simply don't know enough. In fact, as I reread, it sounds like I was wrong. But I need to know definitively. Thanks. S7
Here's a recent correspondence between me and Hawke that I am repeating from another thread. I may shed some light on our conversation, but I am not sure. He seems to be implying that the Frontier does have more lenses than the Sidewinder, which still does not prove my point, however, as the number 21 and 18 could refer to coatings and the Frontier have one or two more lenses than the Sidewinder--or not!
First, my question, and then Hawke's response:
Question: "I and another guy on AirGun Nation are curious about how the light weight of the Frontier line is achieved. Typically, as scopes have more lenses and go up in quality, they seem to get heavier. Yes?
Is it different materials? Is anything sacrificed?"
Hawke Answer: "Unfortunately this isn't a simple answer, and of course our overall designs are proprietary. Yes, the lenses are the heaviest component in a scope, but no - adding lenses does not necessarily improve optical quality. At a minimum in fact, you will always loose a degree of light transmission with every added lens - everything is a compromise. That said, the Frontier line of scopes utilize a high grade, low-dispersion Crown glass and carefully paired lens coatings, helping us achieve efficient optical systems which perform well beyond their price."
