[QUOTE="480sparky, post: 437103, member: 15805"] Incorrect. A 50mm DX lens will project an image large enough to cover the DX sensor. A 50mm FX lens will project an image large enough to cover an FX sensor, .................. [B]but if both are placed on a DX camera[/B]............[B] they will be the same image[/B]. Once again, this is incorrect. It will NOT be the "FoV of a 20-21mm equivalent on his DX". It will be the FOV for a 14mm. The lens is 14mm. Period. It's immutable. Unchangeable. It's 14mm. [B]And it will have the FOV a 14mm lens will have on a DX body[/B]. Let's try this angle: Specs from Nikons' web site: 14mm Nikkor FX lens: ([URL="http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/AF-Nikkor-14mm-f%252F2.8D-ED.html"]AF Nikkor 14mm f/2.8D ED from Nikon[/URL]) FOV on DX: 90° 18-55 DX lens: ([URL="http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/AF-S-DX-NIKKOR-18-55mm-f%252F3.5-5.6G-VR.html"]AF-S DX NIKKOR 18-55mm f/3.5-5.6G VR from Nikon[/URL]) FOV at 18mm on DX : 76° From Samyangs website: (who makes the lens, and is rebranded as Rokinon) 14mm ([URL="http://www.syopt.com/en/camera/photo-lenses-14mm-F2.8-ED-AS-IF-UMC.php"]Samyang Optics, Lenses for Camera â€“ Cine â€“ Photo - VDSLR, Prime Lenses & Third party Lenses[/URL]) FOV on DX: 93.9° Both 14mm's are FX lenses.
