Judging from this and other forums roughly 50% of cameras are reported affected. Of these reported, some will be regular dust. However, in the majority of cases of those who have posted pictures, the stains show very similar characteristics and the tightly clustered dots, line of dots or a lar...

It does look like at least 50% of K-5's have the problem. That also means anyone getting a replacement will have a 50% chance that it also has the problem. Try and check it at the shop? I agree with DrOrloff that if only a small percentage were defective there wouldn't be people on the other ...

We do actually have further evidence though, and that is that Pentax have said that only a very small number of cameras are affected. One would presume that they have a larger sample available to them! "Pentax have said" That's not evidence at all. That's just hearsay (from one employee talking to ...

I put it down to too much Perry Mason in my Stormy Youth. The only point I was making is that any testimony is evidence. Disregard it if you wish, but it's not a major point. I recognise that there's a tendency towards "doom and gloom" on forums, but that's life. We've had a varierty of doom and ...

The K20D banding issues are not long forgotten by me.

[quote:3496ace15f="Mike-P"][quote:3496ace15f="jules"]This was my response from Pentax UK. Dear Sir, Thank you for your enquiry. I understand form your email, that there is a spot on every picture, always in the same place. In this case - most likely - the sensor needs cleaning. Please cont...

At a tiny defect rate of 1% this would be a one in a million occurrence. Even at a high defect rate of 10% this is a one in a thousand occurrence. So I conclude the defect rate is not tiny, in fact quite the contrary. This analysis does assume, though, that the duds are randomly distributed in the...

The K-5 defects cover a very wide range of SNo's. and don't look to be restricted to any range. Someone even commented that because they covered such a big range, the range must also include lens SNo's because it didn't seem possible that so many cameras would have been sold.

Pentax dismissed the K20D banding and SDM problems of the 16-50mm/50-135mm as insignificant as well and because if this they have sold a lot less of the DA* range than they could have. Infact on the USA site it has bordered on hysteria at times with everything bar the end of the world being blamed o...

Maybe, if the replacements are issued from the same production batch, which I doubt. But I think that this is also a reasonable assumption given that: The problem is being reported all over the world so logically from different batches. From the reported serial numbers it seems to affect all ...

I just picked up my K5 yesterday and the first 6 shots I took were testing at f22 on a sheet of glossy photo paper, with the 35mm macro ltd. I wanted to see if the problem was there initially, It isn't!! Serial no, 3913.... But that doesn't mean it won't appear after some use, I am about to up...

I want to wait a little before shooting video and see if it appears just shooting pics, I am being very methodical with it at the moment. My K5 shutter count started at zero but then so did my K7 :?: The K5 is up to 85 on the shutter and I have checked it 3 times already and it still looks ok, ...

That's a better way of doing it :lol: At least you will know (or hopefully you won't know because the marks don't appear :lol: ) what the exact cause is. Good to know about the shutter count as well.

And that's why I would never buy camera equipment from somewhere like Jessops. I can't imagine them going the extra mile. I think we'd go a long way more than most people, to be honest - although you wouldn't get the loan camera!
