Wide Angle Len for D3100

[fmeeran]

btw anyone know those 3 lens recommanded by our friend in the 2nd post
what body can they support?
or anyone can intro me a website when i can check on what body can support the lens

Those 3 lenses are for the dx or aps-c crop cameras. All have nikon mountain lenses, and while you can also find canon mounts for the sigma and tokina.
They will all mount on the nikon D3xxx series, but only the versions with built in motor will Autofocus on it.
Try the nikon, sigma and tokina websites. They give body compatibility for the lenses.
Do note that in nikon you should look for af-s, sigma for hsm for built in motor to autofocus.

both the nikon and the sigma will be able to autofocus on any body, including yours. for the tokina, you need a D90 or above. it will still function with full metering, but you will need to manual focus.

You are looking at Wide Angle (Normal) or Ultra Wide Angle?

The Kit lens 18-55mm is a Wide Angle lens at the 18mm end (Full Frame (FX) equivalent 27mm). If you find that not wide enough, then you go down to the 11-16mm (Full Frame (FX) equivalent 17-24mm) and that is very very wide on the 17mm end.
