Hey so I have an NX8 4-32 F1 MOAR and have had it for about 2 years now and earlier this year it seemed like I couldn't get the target image to focus as well as I got accustomed to. So I sent it in and they said the internal focus ring broke so they fixed it and sent it back. It was all back to normal until the other day seems like the same thing is happening again. Have any of you guys every experienced this issue?
