Canon, Nikon or Sony DSLR?

Hi I'm 14 an don't have a huge budget i'm interested in photography and videography I'm looking for a camera I can take and use for photography a level at college in about 2 years so I want the camera to last along time and have relatively cheap lenses such as less than £300
I would like to get lenses such as 8mm fisheyes
35mm
50mm
Which is the best camera in order Sony canon or nikon I would like to use it for a good quality short films to thanks

Hmm it may be a bit hard to get a DSLR for that price. I would go with the Canon EOS Rebel XS. I have the Canon EOS Rebel T3i and I love it! The Rebel XS is just an earlier model! I would recommend it for sure! It's an amazing camera if you're just starting out!
