Originally posted by gump I have been using the K70 for over a year with the 18-55 kit, 16 mm rokinon, and 55-300 PLM. It has served very well for outdoor photography. It is my first DSLR and the learning curve was not too bad. Upon reflection (and money) I would have gone with the 18-135 based on reviews and opinions on this site.
I'd say go for it, I've had an 18-135 for many years now, at least 8, and it has been by far my most used lens. That being said, buy a DA 55-300 to compliment it. With those tow you're all set to start looking at primes, like the DAF 100 macro and DA* 55 1.4.
With those 4 lenses you can do just about anything.
