Re: [APML] Nikon 180mm f/2.8 ED

I've seen some sort of abberation (fan shapped stars at edges) with TP at
f/4 and even f/5.6 with my Pre-D autofocus 180 ED. It's also there with
color film but barely noticable except under high mag. I assume this is
chromatic abberation of the UV wavelengths, but I'm not the optical engineer
for sure!
