[QUOTE="BackdoorArts, post: 233755, member: 9240"] OK, here's a very quick and dirty comparison of field of view between the Sigma 15mm full frame fisheye and the Rokinon/Samyang 8mm DX fish. All are straight out of the camera with no post processing corrections, only resizing for uploading. Sigma 15mm on a D600, f/9 [ATTACH=CONFIG]63198._xfImport[/ATTACH] Rokinon 8mm on a D600, f/9, DX mode [ATTACH=CONFIG]63199._xfImport[/ATTACH] Rokinon 8mm on a D600, f/9, FX mode [ATTACH=CONFIG]63200._xfImport[/ATTACH] File size on the DX crop is about 1/2 of the full frame shot. As you can see, the 8mm will give you a slightly wider field of view, around 12mm in the DX crop, and you can squeak out a little more if you crop on your own and shoot in FX, and even more if you leave in the black corners and do some content aware fill in Photoshop. That said, you're getting only about 44% of the resolution of the full frame shot (~10.5MP's with the D600, less than 5.5MP's on the D3). [/QUOTE]
