A Pentax K200D is an older camera APS sensor... K-Mount DSLR. Takes great photos... Only 10.5 Pixels, NO VIDEO... however the images are very good.. Probably pick one up fairly cheap since It was purchased in 2008.

Well you can go the "Hard knocks" route, and kind of learn that way..or you could join a local "Hands on group". or you can find a school or class and sign up... Photography is a learning experience.. Different situations dictate what you need to do in order to get a 'shot'... Learn the basics; ISO,Shutter, Aperture... the rest can come from trial and error, or mixing with other photographers, and a beginners course.
