3x9x52mm scope is as clear as it can get at 20 yards with the front objective lens set at 15 yards. I can adjust the front objective lens to 100 yards with 3x magnification and it's still clear as a bell. If I increase the magnification over 5, the image gets very blurry set at 15 yards or 100 yards, and the scope is useless at that point...any thoughts?
