K-5 AF under tungsten light issue ....
Not sure how much it's developed since you posted this, but there doesn't seem to be much support of the same intensity as the OP! Agreed. The support from Pentax in a calm and polite manner. :) Dear Sir, Thank you for your enquiry. Pentax is allready aware of this issue. This issue ha...

JR is partly right, in interpreting what I meant. The other part of what I meant is this.. Go read Ricehigh's Pentax blog, then look at a few rants around here and other forums and answer this: Does it really help a company that has such a small market share as Pentax if a handful of excessively vo...

I do a lot of F1.2 and F1.4 shooting so this issue is important to me. The f1.2 is manual focus anyway, but I'm learning to ignore the AF indicator with it use my eyes. However the Sigma 30mm f/1.4 is a lens I want to use the AF with. I'm sure it'll get fixed before too long. :)

Focussing is fine with the assist lamp but that doesnt' come on until it's darker. I don't understand why it has to be so dark before the focus assist light comes on ... why not have it so the user can switch it on or off at will rather than letting the camera decide.

Surely all cameras will mis-focus under artifical lighting due to the slight difference in the wavelength. After all the focus point for infra-red is noticeably different. Come on you Wikipediacs! (Where is Anvh when you need him?) :?

AF systems cannot focus in every situation. Some examples are listed in the handbook. There's still a place for manual focus and the human eye.

Ok, just tried the silent 1.02 firmware update - the v1.02.21.10... (official one was v1.02.21.07). It has NOT cured the low light FF problem on my K-5. I did exactly the same focus tests with my K20D to compare and it focussed spot on everytime.

Falconeye from the 'Other forum' said ... I can assure you that Pentax management (in Europe at least) is urging Tokyo to solve this as soon as possible. It is a meeting topic. It definitely got full awareness from Pentax management. I also heard between the lines that engineering is working on...

Carry over from my youth when I was in Martial arts. I couldn't agree more. But we can't assume that people providing, even noisy, constructive feedback on the 'Internet' aren't also applying temporary workarounds when they can. The behaviours aren't mutually exclusive ya know :) Try the work...

Could it be that not all K-5's suffer from this? I had my first one replaced by SRS last week and apart from the now clean sensor it seems to focus faster, I do not seem to have any FF issues or suffer from AF issues at low light even when I try plus I no longer have any issues with may flash on pTT...

Have you done anything about it, e.g. contacted your dealer? Same as smeggy. Just waiting for a firmware fix (hopefully). I came across it by accident, thought it was me doing something wrong, tried a few more times and got the same FF and then found and read the various threads... :( Yeah I came...

My replacement arrived today. I've just done some very quick testing, and it appears to be a lot better than the first one, if not suffering no FF at all at f/1.7 in low tungsten light. I'll do some more testing tomorrow, but my instinctive advice, based on a sample size of 1, would be to send...
