I love the nx8 SFP haven't really noticed it being bad at all, I have four of them and can tell you probably the problems people are having is they set the optic up on lowest power for their shooting style and eye relief only too find that the on the high power is where you should be setting it up at as with any high mag scope
On 32 power the eye box is very small. The length of the tube is the issue. Some love it some like me sold it.
go look at one before you buy if possible.
