Originally posted by Digitalis The Lee Filter holder does take polarisers, I use them on a regular basis.
Remember, we were discussing the super-wide bulbous lenses like the Nikon 14-24mm and you brought up the concern of not being able to easily use filters and, to do so, you need to pay A LOT for Lee's design. But, Lee's version
for the 14-24 lens (SW150 System) does NOT take polarizers. See this link to their video:
The LEE Camera Filters System - Includes Filter Holders, Adaptor Rings and Lens Hoods. On the bright side, Fotodiox already has such a filter system for the 14-24 that takes polarizers at a much more affordable price and soon they'll be offering split grads for it. When trying to bring down the sky exposure, combining a split grad with a C-Pol allows for a less powerful grad to be used, making the transition much cleaner and natural. This is important for my application.
If Fotodiox split ND grads are truly neutral (and not screw things up like Cokin did with their more recent X-Pro filters), then Lee is going to have a lot of competition on its hands. Resin is fine for me because I can live with a few minor scratches if the price is right, given that you can never see them anyway (they're so close to the lens). I don't know how expensive it is to make a good split grad, but the way Lee prices them, you'd think it was close to impossible.
As far as the Pentax 645D new 25mm lens, it's a $5K lens. For that price it should have a rear filter slot, given how Pentax designed the camera for landscape photographers. And, you're still stuck buying a filter system for split grads.
