k5 intermittent fault
Don't spend any more time trying to diagnose faults - get it back to the shop that sold it to you, or send to Pentax. Even though the one-year warranty may have expired, the camera must be "fit for purpose" for a "reasonable" amount of time. If you don't get any satisfaction, try issuing a claim thr...

af adjustment on zoom lens
Hi Joe, your profile seems to indicate you're having a nightmare with lenses although your gallery looks fine. If camera or lens isn't doing what it should then surely it's a problem for the retailer. Until joining this Forum I'd never heard of such problems. I've asked pro friends of many yea...

af adjustment on zoom lens
What are you trying to shoot, Redbus? And with which body? I presume you have experimented with the in-camera focus adjustment? In most cases, stopping down a little will allow DOF to take care of minor focus problems,but if you are shooting wide-open it's another matter. The problem SHOULD ...

Biotar unable to infinity focus
Hi I cannot focus my Biotar lens to infinity, even though I have a genuine Asahi Pentax mount adaptor (or so I hope: it fits flush and it has the words ASAHI PENTAX JAPAN engraved on the front). The actual lens model is: Carl Zeiss Jena Biotar f2/58 mm (10 Blades). Has anybody experienced this pr...

Biotar unable to infinity focus
Valentinus, Have a look at c't Digital Photography 4 (2011) They have a great article on using M42 lenses and adaptors on bayonet mount cameras. Seem like there are certain combinations which will not focus at infinity, or conversely focus at infinity a long way before the lens marking. Conclu...

Biotar unable to infinity focus
... there are certain combinations which will not focus at infinity, or conversely focus at infinity a long way before the lens marking .... Conclusion is that it is really a matter of trial and error as to which combinations of lens and adaptor work, and which don't. Like bento2 asks - do you me...

Biotar unable to infinity focus
Hi Doc and Bento and thank you very much indeed for your kind and very useful answers. Sadly, I don't think I'll have a chance to verify what the real problem is, since I've lost both my K-x and Biotar lens. Just as I was going out of the train I got a phone call that made me forget to pick my rucks...

K10D focus problems
My K10D has developed focusing problems. They just seemed to become more and more common, and right now its completely off. At first I thought it just focused on the wrong place, but then I realized it seems to be horrible front focusing. These are consecutive images, both focused on the horse, ...

K10D focus problems
The subjects you have photographed are not the best for demonstarting at 800px what is and isn't in focus. Try being at 45 degrees to a brick wall and mark a spot on the wall that you focus on. Then use the widest aperture and see what happens. If you use a tripod you will eliminate camera shake....

K10D focus problems
This is not a camera shake issue. I have reset the camera through in camera software, is there another way? Maybe these will help elucidate the problem (click for original size): BTW, I typical point the center square between a contrast line (colour divide, skyline, etc): Focused on the top of ...

K10D focus problems
Not the right sort of subjects I'm afraid, we need something more obvious at closer distances. Buildings, brick walls, etc lens themselves better, so we can see where you are focused. Camera shake is always present without a tripod, and sometimes with. It is just vastly reduced as shutter speeds ...

K10D focus problems
I agree with John and would add that atmospheric haze isn't going to help when you are focusing on such distant objects. I did once have a problem with my K20D when it started back-focusing with every lens and I lost a lot of good images. It was particularly noticeable on portraits with sharp ear...

K10D focus problems
Gartmore, I have made the hack. Then I had the problem of huge deviations for different focal lengths. I don't believe its any of that because my camera has had its failed focus and not so sharp images before. Not like these though. When, as evidenced by the shot of the horses with the stone i...

K10D focus problems
So I eventually got tired of this and sent the camera to Reflecta in Spain, which is the reference support for Pentax in its portuguese site. A slow and opaque process followed (codes to track repair budgeting didn't work), I've gotten a quote for 314 Euros. "Main base cam dig" + labour + postage...
