There will always be QC issues involved in whatever product man will make. That’s why a warranty is made compulsory in every product.
Thankfully with Pentax K10D, one can access the Debug Mode and fix any focusing problem without sending the camera back to the company. Imagine spending weeks without your camera. It’s just like not having your (2nd) wife for a long time.
I knew my camera was back-focusing a bit. It was bad enough that it forced me to buy the Katz-Eye Split prism and stick to manual focusing. However, there are some situations that MF is just impossible, especially in capturing fast moving events.
Last night, I had the courage to fiddle with the Debug Menu using MAKC the Russian’s hacked program. It worked. Using Yvon Bourque’s Focusing Test Chart, I was able to correct my camera’s back-focusing problem by dialing +140um adjustment. It was that bad. I knew someone else dialed only +90um in theirs.
I wonder if anyone else has done any AF recalibration with their K10D. If you have, what setting do you use?
To those that have problematic AF, I suggest they do the same. It is not that difficult to do and I guess it will improve your percentage of keepers!
