First Official Statement by Pentax about K-5 "Sensor Stains" Issue

They have just published their official statement directly from themselves about the issue for the first time, ever:-

http://www.pentax.jp/english/news/announce/20110126.html

Quoted:-

"To PENTAX K-5 Digital SLR Camera Users

We would like to express our heartfelt appreciation for your patronage of PENTAX products.

We deeply regret that the first shipment of our PENTAX K-5 digital SLR camera included some products with a stained image sensor — a problem which we believe was caused during manufacturing — causing them to occasionally produce images with spots which look something like water drops, and which users cannot remove with ordinary cleaning methods.

All users of these defective products will receive free repair at our service center.

We sincerely apologize for any trouble and inconvenience this problem may have caused. We also promise to do all we can to achieve the highest level of quality control in the future, and eliminate any worries our customers might have about our products. We sincerely appreciate your kind understanding and cooperation regarding this issue.

Detail of problem:

Spots looking something like water drops may appear on recorded images under certain conditions.

But would this be the end of the story? I am afraid NOT.. Just see a few of all those recent reports by various different K-5 users about the re-occurrence of the same issue after repair/replacement/cleaning of their original K-5 units, as below! :-o It seems that the *root* cause of the issue has not yet been completely located and totally eliminated. >:-(

Not really.. The statements made are rather vague.

RH, the real info what you should report is: "O" mark next to SN# on the box means - checked OK, no stain. Please be helpful instead of "Not really..vague". Thanks!
Who said that??

You are funny, it's the fact. The circle mark is positively on our 2nd body's box placed in front of SH# 3909xxx. Not on the older 38xxxxx though... Read the link I provided as well...
You're Pentax? Nope!

Read again the PF s/n database, the last reported sensor stains affected K-5 is with s/n 3959 something. So, your claim of s/n 3909s do not have the issue is not substantiated. And bear in mind K-5 people have started to report the "stains" re-appear again after more use.

Anyway, good luck to you! My humble blessing..

No, as you, I'm not Pentax. If stain appears, they will give me a new one. No big deal...
