Look up M42 lenses on eBay and grab an m42 to ef-s adapter. You can find really cheap and good lenses that are old that have full manual capabilities. I have six different lenses that work well and I spent less than $150 dollars for all of them. Grab small ones that you think you need. That aps-c sensor size has a 1.6 crop factor and getting wides can be a pain in the butt because of it.
