17-40 - slim fit filter required or not ?
« on: December 13, 2012, 11:45:25 AM »
Hello,

I have a Canon 6D and I want to order a 17-40. I am wondering what filter I need, slim fit (slim size, ... whatever you call that) or regular size. If I use a regular size filter will I see vignetting?

In addition - is it possible to stack filter? E.g. add on top of the UV filter a pol filter or will I see vignetting? My question is not related to the mechanical possibility but just on the optical, so will I see at 17mm the filter in the picture?

Thanks a lot for any help.

Best regards

I am using the Hoya Pro1 Digital filters, which have a 4mm rim and don't cause any issues with the 17-40. Stacking a second filter does produce very noticeable vignetting at the widest setting, however. I'm guessing the maximum stack height is 5-6mm.
