Originally posted by dgaies Have you considered that candlelight, which had a color temp of 1800-2000K, might be outside the range for which the AF system was designed to work? It's certainly outside the range where AWB works.
Maybe I'm wrong, but I would expect a semi-pro camera like K-5 (or any similar model from any brand) to be able to focus in these circumstances. But no matter, I have replicated the same results in tugnsten light in my living room.

Do you have a K-7, and if so, does it respond the same way in this focusing test?
I don't, sorry. It'd be interesting to know, but the test setting is simple enough for any forum member to try and reproduce it with any camera/lens combo.
Originally posted by Pentaxeros The problem is only with lens focusing screw, and only in low tungsten light conditions.
SDM or HSM lens, it does not, with SDM or HSM, the focus is perfect in any lighting.
Pentax, correct this by firmware soon.
Greetings ...
Two important things:
1) It's not tungsten light
only, as I've shown in my post here, (Pentaxeros probably doesn't remember that I have posted the same images at the Spanish forum; either that, or he has tested his K-5 units in candlelight and has not encountered the same problem).
2) The automatic translation of his post is wrong. It should read "Pentax
will correct this by firmware soon", which is what he's been saying over at the Spanish forum for two weeks already. Given his tight connections with the Spanish Pentax distributor, I think we can take his word for it.
