Don't let this one go guys, check out the fish eye thread to see some amazing shots from this lens. I had one, and stupidly sold it, to fund a home purchase.

Relevant news re malfunctioning AF under artificial light

Dear Jolepp , In case a person uses the camera only in daylight the relevance is not there at all. It would be the same though to have the following situation:

You buy a JEEP but with this JEEP you can only drive on tarmac. In case you go offroad your car will get stuck !!!!!!!
How many people do you think will buy this JEEP ? For most of the consumers of JEEPS these days the off road capabilities are not very relevant but you want to KNOW that it can take you throug terain in case it is needed.
A K5 owner wants to be sure that in case he or she takes a pic under artificial light with wide apertures that the focus is correct as the camera is valued as a "king of the dark" in APSC size by us photographers . Wide apertures and low light go together very well as you know.
I don`t know why your postings are all directed towards "softening" the issue and not in forcing PENTAX to act towards an UNACCEPTABLE issue. Maybe you should put your tamron 17-55 once more on your K5 at 2.8 aperture and shoot a bit in your living room or wherever the artificial light is on. I bet with you that with this aperture hardly any of your pics are in focus . (having the settings unchanged compared to proper daylight shooting)

I want to ask you kindly you being a Moderator to help us shooters that experience high relevance with the issue to bring it towards PENTAX attention rather than trying to smooth the matter.

Real photos (not test shots) showing the "string of pearls" stains?

A quick lesson in history! After WWII, the US began in the rebuilding of both Europe and Japan. When Japanese manufactures began producing, they quickly got a reputation for two things: cheap prices and junk (ring a bell with China today?). The Japanese turned to Dr. Deming to learn how to stop making shoddy products. Deming taught them that quality doesn't cost, it pays. The way it pays is two fold: it actually lowers manufacturing costs by eliminating needless inspections and waste, plus it enhances the public product perception and garners more sales. The Japanese literally took this to heart, designing their processes to eliminate the need for inspections by incorporating systems that made defective items so infrequently, inspection was not needed.

Think of it in these terms: what is better, a system that makes 5 defects out of every 100 parts, requiring constant monitoring and inspections, or a system that makes 5 defects out of every 100,000 parts. In the later system, the end user becomes the 'inspector' at the extremely low cost of the replacement of the 5 defective items.

Whether you agree with the philosophy or not, it's how things operate there, and has been in the process of being adopted worldwide for at least 30 years.


All of this is not to say the Japanese do no inspections, because they do. However instead of inspecting individual parts, the inspect the end result. In our conversation / regard, that would be the K5. So, they pull one off the line and check it thoroughly for all aspects of function. If it passes, they may not check another one for the next 1,000 (or more) units. Playing the lottery for a minute, if they check a bad one, then inspection intensifies to see if there are more or if they merely got the "one out of 100,000". If on the other hand, they pull a good sample from the que and it checks out OK, they don't check another for 1,000 units. That means it's conceivable a run of at least 2,000 could have undiscovered issues, and this could escalate to higher numbers if by chance the next inspection reveals another good unit. At some point however, end user reports start to surface indicating an undiscovered problem. Those end user reports are what we are seeing now. The same thing applied to the Toyota throttle issue, and many other problems that lead to the product recalls we have all become familiar with.

Did I say 'quick'? Sorry for being so long winded, but having worked in manufacturing for almost 40 years, I often take things for granted that others may not fully understand, and I wanted to make sure you understood the point I was trying to make!
