NIKON FIELDSCOPE WIDE MC EYEPIECE 40X, 60X, 75X
AM considering getting one of these, but I would like to know if they have rare earth glass eg lanthanum?
I know from my old scope, ed50 that nikon ep are good quality, but how do they compare vs pentax xw ? or vixen nlv ep ? or even televue nagler?
`FIELDSCOPE WIDE MC EYEPIECE` has 72 degree fov right? = same as pentax?
DOes exotic glass affect BOTH colour aberation AND brightness or just CA?
