論價錢論質素, Nikkor AF-S 14-24mm f/2.8G一定係首選.
Recommended Gear
Fisheyes with software: I dislike this way because it's too hard to guess composition, but it is the least expensive. The best setup is the Canon 5D and 15mm fisheye, which is far sharper than the Nikon D3 and Nikon 16mm fisheye. You're going to need all the sharpness you can get in the corners when you stretch it out.
Small-Format Digital: On Nikon, get the Tokina 11-16mm. On Canon, get the 10-22mm EF.
FX Digital, Nikon: Get the 14-24mm. It's the world's best 14mm lens ever for 35mm format cameras. The Nikon 14mm f/2.8 is also great, but not not as sharp.
Full-Frame Canon: I've used the original 14mm L, some of whose results I've shown above. The newer 14mm L II is supposed to be sharper in the corners if you can't shoot at smaller apertures as I do. Neither can use front filters, but the 16-35mm L II (examples also above) can.
Film: Of course you can use 35mm cameras with the above lenses, but real film shooters use larger formats. My favorite hand-held camera is the Mamiya 7 with the spectacular 43mm lens is a favorite, although the goofy viewfinder setup requires me to move the camera into the same position as the finder before exposure for precise composition The best results of all of these technically are a 4x5" camera, on which I use a Schneider 75mm f/5.6 Super-Angulon lens from the 1960s.
Another camera is the Horseman SW612 with Schneider 47mm XL.
