I've got Canon EF35-80mm and EF 80-200mm kit lenses (They are autofocus) from a old EOS 3000 kit. I'm thinking of purchasing a 600D. The camera will be primarily for photography but I will need the video facilty for school concerts ect. Questions? Will my lenses work with the 600D? I'm considering a 18-200 particularly for video work and binning the kit lenses, what do you think? Will teleconverters work with zoom lenses? Or should I look at perhaps a prime or two and use my current lenses. I've got about a 1000 to spend.
