Having recently upgrading to FF 5D mark III, I now find that i am getting vigneting with my 105mm Lee Circular Polariser when using it with my Lee filter holder with 2 slots and wide angle lens adaptor on a 24-105mm F4 L lens. The Lee polariser has got a fairly thick rim which is why probably and i want to keep the 2 slots for filters, My question is i'm sure this is fairly common. So what is other people using instead?
 
I have the same Lee setup - 2 slots, wide angle adapter plus the 105 CPL and have no vignetting at the 24mm end of my 24-70L on a 5D Mk2 - so there's the answer - buy a new lens!! Only kidding.......

TBH - like Mark I very rarely use a CPL with a very wide lens - I get a small amount of vignetting at the widest end of my 17-40 - but that's from "experimenting" - can't remember it causing an issue "in the field".

Maybe worth seeing if a single slot setup would sort the problem - know it compromises the number of filters you can use but a second foundation kit with one slot and the polariser ring might be cheaper than a decent quality thin screw in CPL. Also trying to use the Lee holder on the front of a thin screw in CPL could be a nightmare to keep everything rotated correctly.......... (And still might result in vignetting from the holder)
 
I keep two holders built up, a one slot with the 105mm ring and CPL and a 2 slot.

I use the 2 slot most of the time, if I need a CPL I use the one slot, which lets me use a grad. If I really really need more slots than that I use a tandem ring to join the two holders together, that gives me 2 slots and the CPL, although it vignettes below about 24/25mm I am rarely needing it wider than that.
 
Thanks guys, I guess rather than using a slim CPL on the front instead another holder might be the best solution which i hadnt realy though off :bonk:

Do you only get vigneting with the lens wide open or regardless the aperture?
