K-5 cmos problem

NightPorter · 11-23-2010, 09:10 AM

My friend found his K-5 has the cmos stain problem as the attached photo.
F22 1/3" ISO 100

Hong Kong Pentax dealer told him that his K-5 need to send back Japan to repair for 1 month.
He is wondering to ask the dealer to replace a new one or let them repair it.
He just bought K-5 last week.

And this is not the first case found in Hong Kong's K-5
I think we really need to let Pentax know this serious problem
It is better for everyone who bought K-5, you should check your K-5 more carefully!

I don't know wheather it is dust or not

But Pentax's Hong Kong dealer stated they can not clean it. They need to send it back to Japan to repair
It takes approximately 1 month
I don't understand why Pentax's Q.C. is so poor

Looks like a bunch of dust and a hair. If it is under the filter that covers the sensor, then yeah it's going to have to be serviced, and if it is on a new camera that hasn't been messed with, it is indicative of poor QC at the factory.

eddie1960 · 11-23-2010, 10:16 AM

def looks like dust and a hair, not good, however doesn't necessarily mean factory QC issue
it could also have happened at the retailer (retailers are notorious for taking things out of the box to show people and repacking then selling as new, I don't imagine hk is any better than here for that
if he doesn't want to wait and believes it to just be dust there are good sensor cleaning tolls out there including the Pentax O-ICK1 Image Sensor Cleaning Kit

NightPorter: Thanks for the heads-up. Is this picture a crop at 100% magnification, or is it downsized for the web?

raz-0: That hair looks more like a scratch to me

It's absolute poor factory Q.C.

How shame on Pentax can let this thing happen in a brand new product

No, I just re-size the photo.
It is not hair, it looks like a scratch mark on the cmos

So everyone who had bought K-5, they better check the cmos more carefully

eddie1960 · 11-23-2010, 10:26 AM

the dealer should exchange it, i know most dealers here would (mind you they have to have one to exchange it, they are pretty hard to come by)
perhaps if he has a k7 demo he can give a loaner? don't know what HK retail policies are like

**jbinpg** · 11-23-2010, 10:28 AM

Tell your friend to ensure the Dust Removal is turned on and then trigger it a few times before sending the camera away to see if that removes the dust. And the scratch may be on the low pass filter not the sensor itself. Could be cheaper to replace the filter than the sensor.

Sigh.

So, the battery on my BMW died after 1 week. Shame on BMW for letting this happen in a brand new product!

A camera is a consumer product. If even 1 out of every 100,000 cameras has a hair or dust in it (no matter what the dealer might have done), then the factory Q.C. isn't "bad," they are just not perfect. "Perfect" Q.C. doesn't happen for anything that comes from a factory - that's life.

The Pentax's Hong kong technician also can not clean it up by kit.
They stated it needs to send back to Japan to fix it.
This is not an independent case in Hong Kong.
I know there are same serveral cases in the poor cmos situation in Hong kong
