... Can someone help educate me on why I may/may not want to use a CPL?

Thanks.

Have a look at the link below. It's specific to car photography so might be of use to you.

this thread just made me want a CPL filter, i love automotive photography but the reflections especially in the windows kill my shots.

i dont have money to buy a CPL filter for each of my lenses but maybe just one filter.
should i find a b+w cpl filter for my 10-22mm, 50mm, or my 85mm? im thinking 10-22mm (for rig shots) and the 85mm (for the distance shots) but if i only had to choose one, which would yall say?

^ The one with the biggest thread size which i'm assuming is the 10-22 and then buying step up rings for the other thread sizes.

This. All of my screw on filters fit my larger zooms, and I just have step down rings to mount them to my primes. Beats buying multiple filters.
