Hiya, we all know the nice thread about the DX 10.5/2.8 fisheye. I am in the midst of a transition into FX and would like some comments, pro and con, about the Nikkor AF 16/2.8 and possibly the Sigma EX 15/2.8 diagonal FX fisheye lenses. Film and/or DX performance is not relevant, since the wide angle and fisheye lenses behave very differently on FX sensor. There aren't so many Nikon FX bodies out there yet, but perhaps the situation is a bit different by the end of the week... :biggrin: (Nope, I haven't pre-ordered so I won't be one of the lucky ones). So, please comments (also speculative), first hand experiences and sample photos are welcome.
