Well there's still a  lack of telephoto lenses above 300mm unless you're into paying $6000 or more for the DA 560mm monster which nobody seems to have bought, (I have "never" seen one post from someone who has purchased this lens and only a couple from people who have borrowed it). 

    There range is very complete but some of the designs date from far back and are a bit long in the tooth, also their limiteds lack lens motors and are not cheap but are lenses for life, when compared to the Canikon range Pentax is way behind especially in AF. I also think Pentax needs to address the AF speed situation which limits it's sports usage.

  However, in comparison with Sony, Panasonic, Olympus and Samsung things are pretty bright! 

 

Yes in telephotos there is a gap, but those are mostly expensive niche lenses for bird nutters and management probably doesn't think they can sell many. Low volume also probably explains the ridiculous price of the 560mm. 

 

As far as AF goes the latest cameras (well the k3) are getting competitive (finally) so I don't think they are "way behind". Canon is definitely the leader though when it comes to their high-end AF modules.

 

With the limited lenses they can be small due to lack of in-lens motors and drive speed is never a concern. The only issue may be in-body motor noise, but I am not sure how many people really care. All in all there is a pretty big selection unless you need exotic and expensive fast primes/zooms, however Sigma mostly takes care of that gap. Sure things could be better, but they are far from dire as people suggest.
