Thanks for the reply Navcom. The reason Iam looking at the Z series filter system is that Iam worried about vignetting. I have read that with the P series you can go as wide as about 18mm (DX) to about 24mm (FX) with out any problems. But if I want to go wider then the P series is going to cause problems. As Iam considering moving to a FX body in the near future I dont want to have to buy two sets of filters. I want to get one setup and have it running well into the future.
My use of HDR up until now has been to merge different exposures to get as natural as looking output as possible (EG
Flickr Photo Download: Rice Fields). I dont enjoy looking at overcooked HDR images. But sometimes the work involved in getting it right becomes a pain. The picture before took considerable time to get that small tree right with as little ghost as possible. I have never used graduated neutral density filters but think getting it right in camera at the start will give me better output.
When you say you are using the P series filter holder, how wide are you shooting? Are you using a polariser filter as well as graduated neutral density filters....or are you using just the wide angle version filter holder which I believe only lets you use one filter.
Thanks again for the help.
