Re: 18-135mm lens advice Pentax or Sigma AF

It's a sharp, contrasty, fast and quiet-focusing, relatively light WR lens. It maintains good contrast even in midday sunlight, similar to the DA limiteds. I'm not sure you'd be able to get that with the Sigma.

It has issues with border performance, but I knew that when I bought it. It's my lens for pictures of my kids at school or the park when I can't chase after them with my DA 70mm. I don't care about the border for that kind of stuff, or flowers either (which are my second most photographed subject).

Don't expect a DA* lens, and it will give you better results than you thought you would get. I find the focal length perfect and a lot of fun. My other zoom is the DA 55-300, which, I think, complements this lens perfectly. Lots of overlap for when I need it.

Good luck.
