Here's my question, is "really bad" edge distortion abnormal? Or any edge distortion whatsoever?
Because if any edge distortion whatsoever is abnormal, they have a lot of work to do. All four NX8s I have looked through had it. The 20x versions were quite noticeable, pretty much in the "really bad" category. The 32x not quite as much.
That's a very fare question. I believe mine came from the very first batch so at the time there wasn't much hands on reviews. I sent mine back. It was worth doing so for me. But the fact that so many are noticing it speaks more of the norm rather than mine having been a lame duck.
How bad was the distortion? It was annoying and very noticeable. I can't say I've really critiqued it a lot since, but the use I have had with it it hasn't been there enough (if it is there) to bother me.
