unless the oil is spattering, then being absorbed by a coating on the glass or (think along the lines of curing a cast iron frying pan) the oil is getting baked on to (a porous) glass surface....

the fact that it is appearing after first use implies it is post purchase, not likely it got between the glass AFTER manufacure...
as I guessed earlier, if it happened after use some instances may on the glass and others may be during manufacture... in both cases it may be the same source... oil...

if the glass is defective and porus, then as it heats, individual molecules of oil could settle into the pores and be impossible to clean afterwards........ as in the cured frying pan example I stated...

they are being pragmatic. Who wants to release polished, superfancy photos of rich people while the economy is recovering?
these are people who are wealthy, but really.... other than tradition..... they serve as only figureheads... not like when the monarchy was really in charge...

Yes I could have done better....

reminds me of my childhood.... all those years I thought I was royalty....
Untill I realized what "Royal pain in the arse" meant.

I had asked earlier fo soemone to test this.
thnx.
I bet ir will clean up off the sensor with a cotton swab and lens cleaner or alcohol...
If you try to clean it please post your results?

I am fairly certian there are two issues with this camera, I don't have one and cannot test...
But there seems to be a more rare issie with staining on the aa filter which you cannot clean, and oil fling off the mirror mechanism which can be cleaned.

not really, it just divides the film area into left and right eye views.
IMHO this is an idea pentax should revisit, optimized for apsc digital.

not really just hold a card or your hand between your eyes....... some people have no trouble viewing without anything...

it is basically a mirrored beam splitter that divides the image area into two slightly offset images in one frame.
prints are made showing the two images sside x side and the viewer iether by practice or with aid of a viewing device sees a 3-d STEREOSCOPIC image.
you cn achieve the same effect with two cameras or by moving one camera a couple inches and doin two exposures.
there are now 3-d micro 4/3rds cameras, compact cameras and video cameras that work on the same principal.

I don't know why they call it a "Learning Curve" anyways.
For me it has been a long meandering, twisted, uphill road with more than a few corkscrews thrown in.

this is a great forum when it comes to people sharing.
love to help.



I'd go this route if I were you...
flash from behind, two reflectors one on each side..
aperture set to prevent the highlights from the flash from blowing, then lower the shutter speed until the ambient light balances the image...
hope that helps...

or just natural light if it is good..

a shoe flash should be able to throw a wide enough beam.......just be careful not to get it hitting the lens straight on or you'll get lens flare.
you really need to get proficient with your lighting set ups before you shoot an impatient subject... practice before the day and post some sample shots and maybe I can get more specific...
