The bright spot should be shaped like the aperture. It's lens flare, caused by light
reflecting off internal parts of the lens. Use as long a lens hood as you can without
vignetting to minimize. Shooting from under an umbrella held to "flag" the sun
also helps. Finally, the best lenses with excellent coatings offer more flare resistance
than cheaper lenses. Most Pentax lenses have excellent coating.

That is a symptom of lens flair, and it's caused by reflections within the lens
that design and coatings haven't been able to completely eliminate. The fact
that it's six sided means that your lens has a six bladed aperture. To not
have this type of flair, don't shoot into bright light sources. Sorry not the
advice you were looking for. The other thing you can do with this type of lens
flair is make it part of your composition and just live with it. However on a
good note you have found one of the limits of your lens.
Thanks to both of you. The lens is the smc da 4-5.6 50-200 ed wr—I think you
recommended to me, Paul. I had a hood on but it was a short soft rubber one.
I’d very much like to have the new hd da 55-300mm F4.5-6.3 ed palm wr re lens,
but my body is a k-5, which doesn’t take advantage of the capabilities of this
lens. The lens and a minimally qualifying body—k-3ii—together are beyond me at
the moment.
If your bank account is more important to you than being stylish, you
could extend your lens hood. One possibility would be to take some
construction paper and tape it to the existing lens hood, following the
angle of it.
It might be worth also checking the angle of view at the widest point.
Another thing you could do is take a yogurt tub, put your lens at its
widest, look through the viewfinder with the open part of the tub facing
the lens. Move the tub until the edges of it disappear from view, that
is how far from the front of your lens it can be.
Now cut a hole in the base of the tub so that you can mount it to either
your lens hood, or your lens. You may want to spray paint the inside
flat black too.
