see some people talk about FA35 above, my FA35 has no problem with front / back focus in low light both before and after update. Auto focus accuracy is also working as good / bad as before.
Cool.

Thought I'd add my 2 cents. V1.13 my AF fine adjustments were set between +4 and +10 for the three lenses I have left. The DA*55, DFA100mm/WR and the DA*300mm. Oddly they'd need re-adjustment at random intervals, sometimes the next day, no idea why and that part I'll continue to watch. However I updated today to 1.14, and so far with random testing of the three lenses (indoors, over a couple hrs with multiple lens changes) I've not had to manually refocus yet after AF lock. Currently option 26 is turned Off for the first time since I've owned it! I'm hoping I can leave it that way and put this headache behind me At this point I'm not prepared to say any of them focus faster, just a lot more accurately.

It shouldn't matter, but I did resets (all three places) before I upgraded, not after.

Updated my K-5 to V1.14. My DA 55-300mm focusses much better now, without the endless back-and-forth focussing :-)

Cheers from Berlin, jephi

Oh thats good news. Must try mine out tomorrow, I had been finding it a bit disappointing. My DA35Ltd is behaving better too. But then, I was still running on 1.03. So I guess I would notice differences

Nothing new in low light

Ok, I have been very happy about AF improvements, but low light photography is where the magic stops :P

I am not sure about this but I have noticed that my lenses still struggle in extremely low light. When I say low light I mean in a pitch dark nightclub with hundreds of people. When there is enough light for the AF to lock on quickly it's fine, when there is any delay and the lens takes a moment to lock on most of the time the image is out of focus. This type of behavior was frequently experienced with my D700 using a Tamron 28-75 and SB-700 so I can't blame it all on Pentax.

There is only so much firmware can do -- if the sensors can't handle the low level of light, then they can't handle it. Firmware can't work magic.

I agree, that's why I don't think the firmware has anything to do with that issue. However, I really think the AF speed has increased after applying the latest firmware, which is fine with me.

Just updated today...and for the 1st time in history, my K-5 is able to function with AF calibration OFF!

Sounds like a great achievement, but in reality it's sort of dumb since my k10d and k20d never needed any AF adjustment, they were just magically correct.

The low light AF has not changed, some lenses are good with it, some are terrible with it.

Just out of curiosity, which ones are good?

Just to mention a few good ones: Tamron 90mm macro, most of the limiteds (have not used the 15 and 21 indoors, so I can't really tell on those), Sigma 50 1.4, DA*55 1.4. The last 2 are sort of obvious because of the speed.

So far, in my experience, the Tamron 90 macro has been my most reliable (and used) lens. It's got a pretty nice FL for me, good for portraits and macro, AF never fails to lock, and the AF is highly accurate.

While I was testing the AF with my lenses, I noticed something strange...

I was testing AF-C, using a Tamron 70-200/2.8 @ 200mm, and I was quite blown away by the speed and frequency of the AF. The camera was constantly on the move, the AF motor always whirring and quite nailing the focus, without hardly a heartbeat between focus updates... Felt like a machine gun!
But when I tried with shorter focal lengths (@70mm and with a FA50/1.4 and a sigma 30/1.4), AF-C became very reluctant to move, doing updates every half seconds at best...

Don't know if it was that way before 1.14 (never really tried), but I don't understand why there is such a difference... I'll try some more tonight...

I just updated and think my Sigma 70-200/2.8 HSM II focuses a little more accurately and far more distinct in a really dimly lit room. It feels a bit as the searching range is smaller when it's close to in focus. I can't say that this is the real case but my gut feel says it is. I upgraded from 1.12.
