so from what I'm seeing you have to wipe both off for it to be particularly useable.

here's my ACRO. Literally the first ACRO p2 ever posted by someone on /k/ btw, I got the very first batch shipped to people who weren't reviewers. Shooting side by side in constant rain I found no practical difference between it and my friend's RMR, except that the ACRO was much harder to see through with water on the rear lens. Both needed cleaned to really use properly.
