Wondering which one would be better with this kit? I'm thinking the 105 would be better on paper since it seems you can rotate it and get it more dialed in compared to 90 degree increments of adjustment with the 4x4 CPL if you're using GND filters. Since I already have a regular CPL that threads onto the lens, this whole kit is strictly for using GND and ND filters and I want to use a CPL with it as well. Just wondering what everyone's thoughts are on this and if anyone can give me advice from personal experience. Both of the CPL's are hard to find as they're about always out of stock, but the difference is price......the 4x4 is about $180 and the 105mm is $300. This kit with almost exclusively be used with my 17-40L if that makes any difference. Thanks!
