Was testing mine against a 20x50 just last night, for me it was a lot better in the dark corners at 50 mag. I have got the ft2 ret in second plane. Testing it at night i have found i can see more thro the scope than i can with naked eye. There is a lamp post at 30 yards in front of my house and i could not see the id plate on it. Using the scope it was not a problem could read and range the tag no problem.
...ah and forgot to mention that I was ranging thro double glazing as well so the "real" image would have been even better - but was still clear and snappy on range
The ret was a little hard to see, but I got the illuminated ret so a single click on the dial and ret was back but bear in mind that it was DARK ! not dusk, but dark.
