K-5 AF under tungsten light issue ....
Well, arseholes! I finally got round to checking the replacement K-5 tonight, and.... it's got a problem. It focusses great in good light, focusses great in all light oudoors, and even focusses well in darkness if the AF beam comes on. It focusses great by live view in all lights,too. Under...

K-5 AF under tungsten light issue ....
I finally got round to checking the replacement K-5 tonight, and.... it's got a problem...... .....Under dim tungsten light and focussing by the viewfinder it focusses in front of the target. At f/1.4 - f/3.5 it's enough to leave the subject completely out of focus. Well, this could be good news...

K-5 AF under tungsten light issue ....
hmm. That matches with last night and today trying to focus on the moon. Last night with only the K5, the first shot was good, the remainder pants. Today during the day on the K10 the same lens was fine and all the k5 shots are good. Other focus in daylight was absolutely spot on. Calibrated m...

I messaged again 03/03/2011 - 16:10 and Chris did reply and said he'd call Pentax in the morning ( today, 4th march ) and let me know what they say. Haha you and me both Smeggy. I got various responses from Chris, today he said that he has left multiple messages for his Pentax contact but has had n...

I'm going to ask Pentax UK directly tomorrow at the Focus on Imaging show in Birmingham. Unfortunately had to cancel today. If anyone is going to the show can you ask them about the Low Light FF issue

Did anyone who went to the Focus on Imaging show today ask Pentax about the K-5s low light front focussing problem?

K-5 AF under tungsten light issue ....
I can't do anything until this serious issue is fixed. I don't really understand this front focus low light problem, but as my finances are almost at the point of me buying the K-5, should I hold off a while. The K-5 appears to be a wonderful camera, but reading various posts on this forum there app...

K-5 AF under tungsten light issue ....
There are always some issues in specific circumstances. It wouldn't put me off, and it won't, because I don't use AF is marginally lit situations. Even if I did I would be happy that if it wasn't that, with some other camera it would be something else. My K20D doesn't lock focus in all circumstan...

K-5 AF under tungsten light issue ....
John, I have been discussing it with Chris at SRS. There are 'rumours' that the next firmware fix will solve the issue, unfortunately the fix was 'due' three weeks ago now... There seems to be a lot of mis-information flying about whether all cameras have the issue or only some. Some people have...

K-5 AF under tungsten light issue ....
copied from my post in other [1.03] thread ... OK, not so impressed now .... .... been doing a lot of tests ... I will say there is some improvement, but the AF performance on my K-5 is still way behind the K20D. I'll post pictures tomorrow sometimes as it's 3:30an here, but here's the test I...

K-5 AF under tungsten light issue ....
OK .... GOOD NEWS for now. After installing 1.03 I got 100% success in focussing at EV2. Most of the time. V1.03 gives inconsistent focussing. it focusses accurately at EC2 say 8 times out of 10. V1.01 and 1.02 front focussed consistently EVERY TIME!!! With my old K-5 V1.01, 1.02 and 1.03 fro...

Here's the LensAlign I made .... thanks to xbow for the graphics. :) Now I've noticed a strange behaviour with my replacement K-5. I put my sigma 30/1.4 on it and it focussed spot on in daylight without any AF fine tuning. Cool! - it also focussed spot on at EV2 ( most of the tim...

Well the 2nd k-5 is working OK front focus wise. What I've noticed with all 3 K-5s now is that with 1.03 focussing is inconsistent
