Does anyone know of a wide-angle matte-box or filter holder that will take 4X4s and not vignette on an 11mm focal length? I really need to use ND grads and the shot needs to be wide as possible.
I'm sure I've seen some pros just taping their filters on the front side of the very wide angle lenses, but I can't find the link now (I think it was on Shane Hurlbut's blog)
