Wednesday, August 22, 2007Good spotting scope
"Why is a good spotting scope so darn expensive? Why can't I get one that is tack sharp at 60x for under $500, even? "
These are questions that I get all the time on spotting scopes. The problem is magnification. As magnification goes up in any optical system, the demands on the optical system also go up rapidly and thus the more critical optical quality becomes. It is relatively simple to make an optic sharp at 8x and even with two optical systems, you can get a relatively sharp 8x binocular for under $200. 60x, on a spotting scope, however, is a different ball game, entirely. You don't get sharp at 60x with a poor lens, anywhere in the optical system, be it in the eyepiece or the objective. In fact, you don't get sharp at 60x with even an average quality optical system. If you want a spotting scope that is as sharp at 60x as it is at 20x, it is time to pull out the credit card and spend at least $1000. Sorry, there are no shortcuts, here. Comments: |
