K5 Poll

I have this problem it shows up a one very dark spot with haloing right in the centre of the image camera S/N 3865****.The spot is still visible at F11 which I use regularly for my insect photography.
This is a 100% crop at F32

I managed to give mine a quick test today and suspect I have a black spot that has not shifted with a sensor clean, unfortunately the clean wasn't as successful as I'd have liked and it was my last swab so I couldn't do it again, I realy must invest in one of those Polar Moths or whatever

The black spot doesn't look like dust spots do and it looks exactly the same before the clean as it did after, there are other spots but that could still be dirt on the sensor so I'm keeping an open mind on this and will wait till we get more info from Pentax.

Serial starts 3822

is this from a k5 or k7.

thanks mike, avg cocked my comp up so just loaded photome again.

This is from a K5

And another faint one further down!

I think Pentax have a big problem!....67% on here alone!....just think of the quantity world wide!....wow!

Let's hope Sony are responsible.

It will be a drop in the ocean to them.

Evening George!......have you any thoughts on my new title!...

Mine has no spots at all (flash shot of my fridge door), and the ser # starts 3865....
In terms of production batches, I bought it from Jessops (sorry, only local place I could pick it up from).

Hmmmm. Take that back. Tried again, and there's a very faint spot in middle of the bottom right quadrant of the frame.

If my experience working for them a couple of years ago is anything to go by I would not be surprised.

Then Nikon D7000 has probably the same problems then or not?

Doesn't seem to have affected Nikon D7000s or Sony A55s, perhaps there's something about how Pentax fitted the AA filters

The D7000 does have an odd "hot pixel" effect during video (not all D7000 examples). Nikon have responded immediately announcing a firmware fix? No other tech issues reported.

I was looking at a K5 for Xmas and the D7000 as a second Nikon body. I'm now on hold on the K5 until I see how pentax sort this.

Best regards
