What is this (flare?) ?

OK, last night was not my lucky night. K5 + FA31Ltd took a nose dive from about a meter height onto a wooden floor. Visible damage is a bent lens hood (left bottom corner bent a bit inwards).

Testing today.

I have never seen the below before with the FA31Ltd so wonder if this is the result of the incident or normal. If it was the lens hood, turning the camera 180 degrees should change it; it did not (stayed in same spot). Changing position (so the sun does not come in under the same angle) and it disappears.

Happens at all apertures in tested range from f/2 to f/16 (whole stops).

Is a filter attached? But yes, it's flare.

No filter. I've shot the same scene before and never noticed it. Might have been slightly different position of the sun.

Can it be caused by a damaged lens? Aperture seems to close properly without odd shapes.

But it will go in for repair anyway.

Don't overexpose the sky and I bet the flare will go away. Nothing suggests that there's anything wrong optically with the lens as far as I can see.

just a simple comment about hoods from FA lenses.

these lenses are full frame, and although the sun might not be in the FOV for the digital sensor, it is not adequately shaded by the lens hood because the hood is designed for the FOV of a film camera.

I suspect that the artifacts are flare from the sun being between the FOV for digital (which you see in the finder) and the FOV for film (which the lens sees but you don't)

Repair for what? When you point a lens at a strong light source like the sun, flare happens. There is nothing wrong with your lens.

Thanks everybody. I had the feel it all survived but needed a bit of comforting. Hat off for Pentax

I think the lens hood took the brunt of the fall and probably had saved the lens from serious optical damages. Judging from the look of it, the damage appears to be the cosmetic - however, it is still worth getting it checked and repaired.

No doubt ... that quality, solid, metal hood most likely saved both the lens and the camera. Respect.

Just think what would have happened if the FA31 didn't have a built in hood and the lens landed on some easily broken "protective" filter.

ouch! that must hurt, especially on 1000 lens!
---
side note, I managed to whack my 31 some time ago too, the built in hood saved the front element, but one of it's (and front element's) support snapped and become loose in focusing helicoid, jamming it. It had to go for repair by Pentax. I'd check if something doesn't rattle inside your lens...
---
side not 2 - 31 will flare like this anytime sun hits the front element...

Having just received (and fallen in love with) my own 31, and wanting to keep it perfect forever, I must say that that damage photo caused me to have a physical reaction. Not unlike a punch in the gut.
