All,
I just picked up a demo 17-35 from a reputable dealer. There are some grease marks (I think) on the rear element and some spot marks (water, drool, something) on the front element. I do not "clean" my lenses often and I was wondering if the front element, in particular, sports a tough coating (I know it's a T coating) that can be effectively cleaned.
I have Opticlean so there should be no need to rub but I just wanted to know if anyone has had any issues cleaning this beast before I try it.
Thanks in advance for the tips.
