K10D Back focusing Issue
I use two lenses with my K10, the Pentax 50-200mm kit lens and the Sigma 17-70 EX 2.8. I seem to be having BF problems with both lenses. I use the 17-70 a lot more than the 50-200. I am thinking about switching to Nikon, but I want to give the K-7 a test drive. Can I fix the BF problem I am having w...

K10D Back focusing Issue
Wrong forum to ask such a question I'll second Amin's post, we have a few sensitive people on here:lol: As for the focus problem you can get that with any camera so changing brands isn't the answer. If you can afford it then the K7 would be the obvious choice to go for as you already have two len...

Wrong forum to ask such a question I'll second Amin's post, we have a few sensitive people on here:lol: Precisely why I have decided to stay on the sidelines lately and enjoy just reading rather than butt in as frequently as I used to before :wink:. Brad, I would certainly advise you to not ...

K10D Back focusing Issue
I have just gone from a K10D to a K-7 .. huge improvement. I echo that - my K10D back focusses (or front whichever way it is!) Have had no such issues with the K7 - haven't even had to use the focus adjust that is available Andy

K10D Back focusing Issue
I can't actually see a question about Nikon .. just a post about backfocus on a K10D and someone who is considering a move to Nikon wanting to try a K-7 first. My advice is try the K-7 and if you aren't happy then look at another brand. For me its a cracking little camera in most respects but ...

K10D Back focusing Issue
I have seen and read about the K-7 and would prefer it over any Nikon. The problem with Pentax, is that most camera shops don't carry Pentax anymore. I know a place where I can hire Pentax Cameras and Lenses. The K-7 goes for about 50 quid for four days. Pentax and rain go togwther, try that with an...

K10D Back focusing Issue
Find the debug mode on the web, download and then set to work with a focus chart. It`s a global adjustment but you believe you have a problem with both lenses then you ought to find it a help. I set my K10 t0 +200 and it`s fine for me. The K20 by the way has input for making alterations for up to 20...

The original Russian software doesn't work properly in Windows 7, and the MODSET.TXT doesn't seem to work in firmware 1.31. :cry:

K10D Back focusing Issue
Wow, that works now. Thanks again Stefan.:) My K10D had drifted a little - I had to add +6 to get it correct. The GX10 hadn't shifted at all, but then this camera gets far less used/bounced around/etc. That technique is (IMHO) far, far easier than using the Russian software.

K10D Back focusing Issue
When the AF confirmation says it's focused on the subject, but in reality it's focused some distance behind the subject.

K10D Back focusing Issue
What's back focusing? It's when the camera focuses the lens behind the point that it is supposed to be focusing on. Front focusing is the opposite. What causes it is a more difficult question (that I dare not even begin to try to answer at the moment as it's such a complex and peculiar thing).

K10D Back focusing Issue
What's back focussing? Back or front focussing is only a problem that occurs with the use of auto-focus (AF) lenses in AF mode. If a lens/camera combination is back focussing (BF), when you use AF to fix the focus point, that focus point will be slightly behind (further away from) your intended f...

K10D Back focusing Issue
Back/front focusing can occur with manual-focusing when there is a misalignment with the focusing screen or sensor. Then what appears to be in focus through the viewfinder is not in focus on the photograph. There also can be an error with the focus confirmation system (the green hexagon indicator...

K10D Back focusing Issue
This problem does not occur with MF lenses, or AF lenses in MF mode. Is this really true? Given that you get focus confirmation when focusing manually, why might the actual point of focus not be different from where the camera thinks it's focused, and for the same reason as with AF?

K10D Back focusing Issue
In that instance Chris we would still be using the AF system to confirm focus. If the camera's collimation is correct then using our eyes should get the right point of focus, subject of course to our ability to judge that point.
