WOooosei! canon better la! fr MIQ…guess who?
Wish i can help u ^_^…
All Canon camera has built in AF-motor. like EOS 550D
Nikon D3100 does not has build in Af-motor.
But the D3100 can do much better than EOS550D
Try think your budget 1st, and then select a camera. Although D3100 don’t has build in motor but u can try select the lens that include AF motor… If u are a beginner then u can try to buy D3100, D5100 or D90.
Furthermore, u can also buy the Tamrom lens like 70-300mm (Quiet cheap) and this lens has it AF motor.
In simple way, Camera body don’t has built in motor. Then your should get a lens that has a AF motor.
Camera body has built in motor = Lens don’t need has AF motor also can…
