Well, having voted 'no' to marks on my sensor, and having the shots to prove it, this morning I took some ice photos, and was shocked to see significant marks have now appeared. :-( So in my case, no amount of QC of cameras coming off the production line could have spotted my problem, and perhaps...

3821xxx Although the original test shots I took showed a very small single spot to one side of the frame at f/32, I just wasn't worried about it, as I never shoot smaller than f/16 and it simply wasn't a problem. The marks that have appeared are near the centre of the sensor. First shot, no...

If your K-5 has the same problem as most of us, then you cannot remove these marks by cleaning, as they are under the aa filter which lies over the front of the sensor. I would advise you to return it as 'unfit for perpose' and ask for a refund. You have not posted your location, but if it is in...

Kr Sensor Marks?
Could be dust which you can't quite see. That doesn't look problematic to me, the spots are tiny and not patterned. Looking at thread on the other forum, Falk Lumo checked his K-7 and found a couple of suspect marks apparently under the AA filter - he had presumably not noticed them until this issue...

Kr Sensor Marks?
I think it could be also dust under AA filter as I tried to clean it with dust removal and sensor clean. Manufacturers could have avoid these kind of issues if they had a superb QC. They could pay more attention to the key product(sensor - though it's not made by Pentax:)).

Kr Sensor Marks?
I have the problem with my K-5. There are two spots, both small but one quite dark. They only show up in rather extreme cicumstances eg F22 and uniform bright surface like sky or a white wall. I emailed Pentax UK support and they proved quite helpful with a very rapid (same day) respose. They ask...

Kr Sensor Marks?
Also, when looking at the sensor through a professional magnifier these dots will show. If the dots can not be removed by professional cleaning the dots are between the sensor and the filter, and in that case your camera will be replaced. That's the first time as far as I know that someone from P...

K5 Sensor Issues...
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...

K5 Sensor Issues...
Otherwise I can see the K-5 being the best APS-C camera Pentax ever made also becoming the worse selling because prospective buyers will be as sceptical as they are with SDM. I don't have a K-5 so can't comment first hand. My thoughts are that if the sensor and Bayer filter are supplied as a comp...

I got the impression it was contaminated Flourite coating on the cover glass? Vic. Until there will be an official statement from Pentax HQ, everyone's guess or what or what not has been heard, written or said is just guess work (even there is some very convincing pictures on the other site that ...

K5 Sensor Issues...
My original K5 had a "stain" on the sensor which was obvious in a few pictures. It was taken back by the retailer and I obtained a new body after waiting for old stock to clear from the supply chain. What interests me is that the original sensor also accumulated lots of debris adhering to it whi...

Shooting clouds with the K-7
You should get some graduated ND filters. Yes this seems like a something worth trying. I don't mind pp of course but I'm not to happy with heavy pp - which is what I had to do to bring out the foreground in this test shot yesterday. Ideally wait for a sunny interval - it can look so dramat...

Shooting clouds with the K-7
HDR is a good idea or use a PLC filter. I usually use ND filters in various density (from 2 to 10 depending on the weather) but I got good results with a PLC filter as well.

Pentax or Nikon ? please help me choose
There is indeed a standard petal hood for the 52mm filter thread lenses. The Mk II and WR and DA-L lenses are all the same configuration. They are very good lenses.

Best DSLR of 2010
Who cares TT? This is one of those 'vote on our site and we'll target adverts at you' sites. I've got a spam filter and fire walls so it doesn't bother me.:wink: you can vote more than once as well, if you wait for a short period and use different internet clients, as 2008 shows. :twisted:
