I'm in the market for a filter holder and GND filters for landscape and time-lapse photography. I don't know a whole lot about these filters and holders, but I do know the Lee filter is too pricey for my budget.
That puts me in the market for a Cokin Z-Pro and X-Pro holder. I know the Z-Pro is slightly smaller, takes 4x6 filters, and is able to use Lee and HiTech filters as well. The X-Pro is larger at 5x7 and only takes Cokin filters which may not be best for future proofing.
Does the Z-Pro vignette a 14mm and 16-35mm on full frame? Any suggestions on which holder to get?
