Re: Any scopes as compact as the NF2.5x10 and magnif.
PC,
I'm a little surprised by the "red fringe" indicated by the arrow pointing toward the woman in the blue/white-striped bikini. She looks like a natural blonde to me (LOL).
In all seriousness, the "CA" you refer to can be caused by many factors, not all of which have to do with the glass itself. For example, do you wear any kind of corrective eyewear? It can cause differential effects depending on the type of glass (as in different manufacturers) you're looking through. Was the comparison indoors? You can get differential effects through different glass under artificial lighting. There are almost too many possibilities that could account for some level of CA. The best option is to compare side-by-side, outdoors, under actual usage conditions, if possible. Unfortunately, it's rare to have the luxury (or opportunity) to actually do that. FWIW, I have several NF including 1-4x24. 3.5-15x50, 5.5-22x50, and I just ordered another one this morning. I have not observed the type of CA as shown in your pics above in any of them. If you end up going with the 2.5-10x32, hopefully any CA will be minimal in the one you get. Good luck.
