Originally posted by Docrwm Sometimes its the photographer. I do own many electrically motored lenses and still find that ITS NOT THE LENSES. Again, sorry but I'm not buying the PLM for an array of reasons - even to satisfy you and your need for Pentax to be as good as other systems when it comes to AF. Bottom line, Pentax, by all non-fanboy accounts, still lags far behind in AF. My experience with working with Canon and Nikon shooters supports that contention.
Name calling rarely accomplishes anything. But Believe what you want....

All taken from Imaging Resources' Performance stats. No doubt, Pentax fan boys.
Only the best of the rest matches what i do much of the time, and many fall behind.
Educate yourself try out a K-P and 55-300 PLM. By the way we also have testimonials from at least one former Nikon user that this information is accurate.
So am I the Pentax fanboy, or are you the "any AF but Pentax" fanboy?
Your opinion is important to us.
Who's AF is best depends on how you use your camera. I regularly shoot beside Canon, Nikon and Sony shooters, and after a change in pose by the wildlife, I often get off the first shot off, the speed of Pentax AF.s in focus confirmation makes up for my 70 year old reflexes. I also find most of them so brainwashed by the same internet hogwash you've fallen prey to my camera turns their heads and leaves them groping for explanations.
But, if you want to present some actual facts to prove your case, I'll be happy to look them over.
Given a choice between someone who has actually used cameras from both systems extensively, I'm not really interested in anecdotal comparisons. Some guy saying "my camera is better than yours" doesn't make it true. Especially when they use one system full time and have just fooled around with the other a few times.
Please don't try and pull this B.S. on me (us) again.
Pentax is severely limited in tracking AF, though there are youtube demonstrations that it doesn't lag that far behind even there as Canikon people like to make out it does. IN AF.s it has an advantage over all but the most expensive systems. There's no comparably priced system that comes close to a K-3, which is now 6 years old. Different philosophies of AF design, with strengths in different areas. Don't mistake that as "one is better than the other."
I've learned how to get the most out of my system. It stacks up with the best in almost every situation I've used it, I don't listen much to people who claim I can't do things I do. Why would I?
