I have a 45mm Pentax lens for my 67ii. I noticed when I put the P sized cokin filters on it I get the corners of the filter holder. Which size would I need for this lens? The X-Pro or the Z-Pro?
if you find a spare Cokin P filter holder, cut the first two rows, this will allow only one filter and the polarizer. that should remove the corners from the shots. useful for the extra wide angle lenses that need grad filters.
