Hey ho, folks. I'm new to this forum, and am considering one of the sinar p-slr systems to hook my Nikon D700 and D3x to. Just wondering if anyone out there has any experience of these systems, and, if so, how you find it. I'm also wondering what the difference between the p2-slr and p3-slr systems are? I see there are different bellows available. Does that mean a different bellows for standard and wide angle use, or lens type..? Totally new to view cameras, so please be gentle with me. Thanks in advance for your comments.
