Focus Adjustment

Greetings all,
My apologies if his has been discussed before but I am not very good at doing the search routine!

My K5 has not impressed me as regards sharpness, so yesterday I downloaded Yvon Bourque's focus chart and using the FA77 set at 1.8 did some test shots and found that I was approaching middle field (centre point focus) at +10 adjustment. I then tested my other AF lenses - some Pentax, some Sigma and one Schneider and found them to all be pretty much the same as the FA77. I repeated the tests with my K20 and found that at 0 adjustment the AF was correct. This leads me to believe that the camera is at fault.
1.Can I calibrate the camera myself in some way?
2. Sending the camera in under warrenty is not realy an option as I am in South Africa and I bought the camera at B & H in the US.
3. Can anyone give me the contact details of the authorized Pentax repair operation in South Africa?

Thanks in advance!

Hi, have you tried upgrading your firmware.
Some people have reported similar problems disappear after upgrading.

Answer to 1. : no, you cannot. It requires special Pentax s/w not available to users.
Answer to 2. : did the camera come with an international warrenty?
Answer to 3. : PENTAX

Cheers, Bert

Focus Adjustment

Hi Bert,

Thanks for the reply!

I believe I have all but the very latest firmware update and if I am correct that was just to fine tune the GPS aspect. I will however try that just to be sure.

Pentax have outsourced camera maintenance in South Africa and I have identified theam as a company by name of Camera Tek. They also do Canon, Fuji, Samsung et al. Their closest branch is about 350 km from me so not too far - a trip I make quite often.

I presume my warrenty is the standard US one but will look tonight to make sure.
