Thank you, Chris:
This was a good review, at least as good as practicality would allow it to be, the resolution test in sunlight and shadow was a good example. They went to the right town, the right college, and the right person. What was NOT said, however, might have been of benefit to some of the more opto-geeky observers and hunters among us.1. Of the hundreds of brands and models being imported from prominent Asian sources, most come from a handful of actual manufactures. When the AD-7 (manufacture designation) disappears from being the XXXXXXX XXXXX in some importer’s inventory, if it was popular enough, it would show up as the XXXXXXXXX XXXXXX in another’s. It would have been changed in cosmetics, perhaps coatings and, of course, price, so as not to look exactly like the AD-7s being sold by a dozen other importers.
2. The testing was one of the most realistic and rigorous I’ve seen. But, truly waterproof instruments deserve much more than a dunk in a 5-gallon bucket. A fifteen-foot submersion at the end of a pier for 1 hour, and an overnighter in a freezer, should start the acceptability meter, nicely. It should be remembered that most moisture damage or fogging is not caused by being splashed, rained on, or dunked; it’s caused by rapid temperature changes in a humid environment.
3. “We can’t rank by reputation, but Steiner does have a name for making glass that lasts, which may help justify the cost.”
Many of us in the repair fleet referred to them as “the disposable binoculars” and the peeling of the “armor,” when used in a hot environment, was a major factor in causing the Army to drop the Commander from being their M22. Also, Steiner has been part of Beretta Holding since 2008 and a good many to most units are actually coming from China—not Germany.
4. Binoculars don’t provide “pictures”; they provide images. 5. Finally, I would like to know more about his collimation test, specifically whether or not spatial accommodation played a role in the results.
