Are you one of the originators of the FA test? Resolution is not too difficult to understand. "Same place, same time and same person" does indeed cancel out most of the environmental complications. Having a reference scope helps greatly as well. Things get a little more complicated for a few other reasons: resolution alone is not an especially good measure of imaging performance under adverse conditions. It is a good predictor of imaging performance under favorable conditions. To get a better (although still subjective) measure of overall imaging performance of a riflescope, you should be looking at MRC, which is difficult to do. Either way, the basic problems with standardized test done by users is that the results are only relevant to a particular user. Comparing between users who did not do the test together is impossible and that is what is likely to happen. Additionally, there are perceptual issues with bar targets. I am transitioning most of what I do to the TOD methodology and it seems to be more repeatable. |
Yes, test was done between me and my colleague.
It is simplified version from our own in-house test that we use for benchmarking. Also very handy checking tool when our customer feels there is something wrong with optical performance with scope.
Resolution with colors is rude and simplified test alright. But we decided to offer it with with idea it is still much, much better than nothing- as forums are full of endless debate about "glass quality".
I tried hard to figure out how to produce sensible contrast part for test too, but it is impossible for many reasons. Bar test is bar test- easy to understand and produce- and with some practice it gets the job done IMO.
Idea was, and still is, to make database where each scope owner can add their own results. This way part of variation would be averaged away- but it is still rough method and naturally far from actual objective testing.
