>>2627523being a beginner you wont want to get caught up in which lenses are best or comparing cmos sensors between DSLRs. Buy what you can get your hands on. The K-50 is a great first camera and those lenses will be fine. You need to focus on realizing how difficult it is to take a great picture versus a boring picture you didnt put much forethought into. Look for photography cheat sheets like this one
