I bought it mainly for the shooting 25m, 20x and frankly, this is the right magnification to frame c50 sounds spot a target, it is even slightly increase the magnification to tighten a bit more on target. The brightness is decent against by the treatment of the lenses is not really that (price requires) the day are against too big to avoid. A 20x quality is at its pinnacle as very good dive in both brightness and decrease as you get closer to 60x while still correct. If I had a bad word to say it is only on its size, 44 cm long, but even in its case she gets right in my camera bag (large camera bag) in which I carry the stuff. I put 3 stars for the quality of all that is good (notice of a retired person the photograph.), And 5 star see 6, value for money.
