Optimize focus for UV?

Postby adambx » Sun Jul 13, 2014 11:56 am

Hi all,

has anybody tried to focus a tad further than usual because UV has a shorter focal length than let's say red if using the same lens. I haven't done the calculations, but if it might make a difference in sharpness I would certainly give it a try.
Any thoughts?
