Originally posted by MitchellScott Hey everyone I'm new to photography and just got a Pentax K-X with the DAL 18-55mm kit lens. I was wondering what the difference between the lens I have now and DA 18-55mm lens is. Also what would be another good lens to start out with? I'm looking into the SIGMA 50-200mm f/4-5.6, Pentax DA 50-200mm, or Sears 1:2.8 135mm. Here is first photo I took today with my new camera. Any feedback would be greatly appreciated! Thanks!
Nice Wayfarers.. Had a pair just like them since 1995 and is the only pair of sunglasses I've bought in that time.. You'll probably get more mileage out of a 50-200. Can't speak on the Sigma but the Pentax is pretty good. Didn't care a whole lot for it myself, 200mm was never enough so I sold mine years ago.
If it hasn't already been mentioned (I would be surprised), be careful on that sears 135. They are NOT all created equal. Some have large flanges that prevent them from going on to the DSLR Pentax mount. Even though they fit the Film camera Pentax mounts. Others suffer from the dreaded Ricoh Pin Syndrome (RPS) where a pin on them will drop into the AF screw on the Pentax AF mount. That will essentially lock the lens on the camera. Some of the sears 135s have Both these issues. If you're willing to tinker with them, both problems can easily be overcome but do be aware of them.
Really though I would suggest getting to know the camera and practicing a bit before jumping into Lens buying. Unless you really know what you want to do, you'll end up with a shelf full of glass that never gets used (like I have)...
Good luck and enjoy the new camera..
