Please help out a NOOB!!

I'm totally new to the DSLR scene but I was planing on getting a Pentax K-X camera and have a Sigma mc 100-200mm f4.5 macro zoom pentax k mount lens. Will this lens fit on the camera without an adapter??? Thanks for all input...

I didn't see a 100-200 in the lens database - did you mean the sigma 100-300mm f4.5-6.7? As long as it is K-mount, it will fit, and if it is autofocus that will also function normally. Pentax is VERY backwards-compatible when it comes to lenses.

All k-mounts will fit.
