I've found that using a 2X flip-down eyepiece magnifier improved my focusing, especially when using a lens wider than 50mm. But the more than once the magnifier's rubber eyepiece caught on my hard contact lens, in one case making me lose the lens. For this reason, I no longer use it.
It's unsettling how often my beloved Vivitar 28/1.9K shows a reading of only 6 feet when I'm focused on a subject 10 feet away. I really must check out how much of this discrepancy is real, and how much imagined. [EMAIL PROTECTED]
