I am glad to hear that you have no problems with your mkI, I tested mine with the 50mm 1.4 again but although the autofocus is pretty instantaneous it is not accurate at all..

I haven't took it to the service center yet

I spoke on the telephone with the authorised service center and they told me that that's the first time they hear about such a problem with this model (autofocus inconsistency if I explained/described it right and he understood what I meant), strange..


they need to check the camera first and they will inform me..

If this is such a common problem they should cover the costs of a repair, that's the way for a company like Pentax to build confidence.
Anyway I've just searched the Pentax site and found the authorised service center in my town, I hope they will have a solution to this common issue, be responsible and with a realistic cost

More news on Monday

Thanks again for your concern and for sharing your experiences.., live view for a weird reason kills my battery but besides that the meaning of a dslr is to compose your photo in the viewfinder otherwise is like using a compact.


The K-5II may be really great (just as K-5 was when I was searching for reviews..) but I don't care, I have a faulty camera which I can't sell due to that and even if I did I need extra money to get a K-5II which I don't have at the moment. All I am saying is that I don't care if Pentax fixed the problem in the next model, that's their problem. I bought a K-5.
I accept the fact that products have weaknesses but this is unacceptable, there should be a firmware update to fix that or free technical support. The thinking "find a way to live with that" is not enough for me this time.

I took some test shots again and it's disappointing, it was set at -4 giving a raw of fair results in the afternoon, I had to take it to -7 some shots ago and now it back focuses thus I have to move the adjustment again which is meaningless.


I don't now what to do, excuse my whining but I really feel stupid to make sacrifices and wait so long to get my hands on a K-5

yes that's what I am saying too, I read every review on the net about K-5 and everybody seemed to love it.., now I feel a little @#$%!

anyway as long as the focusing problem is not present in all the bodies I am confident that a technician can fix it so it can work like the ones of the lucky K-5 owner's


until then I feel very insecure of what I actually shoot and this is a very bad feeling..

I can't thank you enough for your kind gesture but unfortunately I don't live in the UK, I live in Athens.

I made some more tests with the AF fine adjustment today and it behaves good some times, some other it focuses aproximately 3cm in front and some others 6-7cm back, all this in bright light, with a high contrast (I hope..) center focused item and with f2.0

I purchased the camera used in excellent condition (770 shots) in a trip from a big store in Japan therefore I don't expect support of any kind.


I have used the 18-55 kit lens for a while and I don't think it had issues that I am aware of (but that's not for sure mostly because I used it for scenery etc), for now the only lens available is the FA50mm f1.4

If there is somewhere a k-5 mkI that works fine then there is something that can be done to sort the focusing problem out.., if not there is no chance to keep the camera..


Unfortunately I see apart from one or two cases (Mr Riley's for example) that this model is faulty, worse than that nobody somehow solved the problem. Am I right ?

as far as I remember that's what I did but I just saw that the result which was either very good or..... not good at all, the differences I am afraid is something difficult to measure with accuracy..
