LiveView of the K-5 Creates UFOs / Pearls on Sensor?



See what this K-5 user found and reports (with sample photos):-

http://forums.dpreview.com/forums/readflat.asp?forum=1036&thread=37503804

It seems that the material of the AA (Anti-Aliasing) filter of the K-5 is being changed in status by the heat generated by the LiveView, so that the UFOs/pearls are accumulated and appear (on sensors and images produced) eventually. In fact, this has been suspected by some other affected K-5 users before, that is, their brand new units did not have the UFOs/pearls appeared but which were yet seen after a certain period of time with more use.

One of the reasons I decided to go (a Limited) K-r instead of a K-5 is yet because of this IMHO major unresolved issue with big uncertainty. Indeed, there is NO direct *official* statement of any from Pentax/Hoya for what has/have been wrong and what's going on about all those happenings.. >:-[

This is the first one I see with UFO's and its disturbing, the only thing that jumps to my mind is the combination of this and the sensor stains.

If I recall correctly I read that the sensor stains where the result of a contamination during fabrication or assembly of the AA filter or Sensor.

A lot of iffs, but ... as long as there are no other K-5 appearing with this ufo problem that don't have the sensor stains this may be a result of the same contamination.

While I had my K-5, a sensor stained one, I did use live view a lot while talking close ups from real low angles (camera almost sitting on the ground) and didn't notice any "ufo's".

I had my camera almost a month before I returned it, and now 3 weeks after returning it got a phone call that the new one will be in the store where I bought it within the week.

Just a sidenote - stepping back from the K-5 to my K-20 was a lot harder than I expected, proving how good the K-5 is .

I wish you a good time with your "limitation" to use K-r.
K-5 is really a great camera and does a good job for me!!

I am just an entry level user who only needs an entry level DSLR. So, the K-r is the body that suits all my needs! ;-D

I saw it once on my Kx after something like 10 min of video recording (just one pixel). I got it in the next 5 photos and never showed again. take a deep breath! Say: nothing serious. Now convince yourself it really is nothing serious

You are so right! Pentax has been doing the same coverup on the SDM problem for years now. Pentax quality control is certainly not what it was in the glory days of the company. Nowdays, it seems like Pentax is satisfied as long as there are simply more people happy than unhappy.
