Canon Eos 50d 17 85mm Is Lens

I want to get a Canon EOS 50D DSLR?

I'll be all right trigger days. especially the nature probably. and activities daily with my family. What type of lens I suggest you start? Some I've looked. 18-200mm 18-135mm 17-85mm EF-S does not really know. Thank you a lot!

might be a little more to be used alone every day to take pictures of the family only, try a cheaper SLR like XS
