These are better. The subject matter is incidental, these aren't beauty shots. 
First, the Pentax 150/3.5. This is a good representation of the
resolvance of the 150. Look at the grains of rock in the granite -
sharp and clean.
It is interesting how each lens has its own color points. In this
case, the lens shows very true colors. I am happy to see that
I can show at least some of the accutance of the lens here.
It's equivalent to a 90mm lens in the 35 camera world.
I love the lens.
Pentax 150/3.5
f:3.5 (wide open) and 1/500th
Provia
Next up, is the Pentax 55/2.8, almost wide open. Even the
corners at a nearly wide open f:stop are showing nice crispness.
I underexposed a little here. The color is a little cooler than
the 150. This 55mm lens is equivalent to a 32mm lens in the 35
camera world.
Pentax 55/2.8
f:4 and 1/500th
Provia
Finally, the Arsat 30. I am definitely getting pretty good output
from this extremely wide lens. This is wide-open at f:3.5, and
showing good crispness and detail for that tough setting. The
Arsat 30 is equivalent to a 16mm lens in the 35 camera world.
There was some "curl" in the transparency on the scanner, in
the upper left hand corner, so discount that area in comparison
to the pretty sharp rest of the image. I'm impressed!
It's slightly warmer than the Pentax 150.
Arsat 30/3.5 Superwide
f:3.5 and 1/500th
Provia

Excellent results, and you describe each lens beautifully.
The 150 does look super!
Yes, I want one of each

Thanks you guys. In actuality, I could recommend all of these lenses
as being worth the purchase. I am gratified that I got a "good"
Arsat 30, as I've heard there were possibly some quality control
issues. That said, the distributor of the lens in Georgia told me
that there are no longer very many "lemons" as the prep and
assembly has been improved.
I am blown away, actually, at the Arsat. It's not a perfect
lens of course, and has some chromatic aberrations in the
red and purple spectrum as well as some pinching orientation
because it is so wide.
All in all, the Arsat would be an 8 out of 10 for me. I'd say
the pictorial results might be a 7.5 and the "usability" would
be a (surprising) 9. I look at using this lens quite a bit more
than I originally anticipated. 
The 150 and 55 would both be 9 to 9.5 out of 10. Just plain
superb. I guess they would be considered a 10 - except that I
think you can possibly gain a bit more with a high-end Leica
or Zeiss glass. Probably not MUCH difference, though.
I've always appreciated the comparison of lenses, and the
photographer's own viewpoint on "real-world" results, which I
think was started by Orio. So, I'm happy to return the favor
to our members.

Wow great pics and wonderful colors.
I have not very often seen such a blue.
Seems that there was no dust, fumes or other nice ingredients in the air. Must be great to stay there.

Great shots as usual, Larry.
The only "problem" (so to say) for you could be that the Arsat delivers a quite warmer tone than the two Pentaxes. If you shoot slides to be in a series with all these lenses, I think you'll have to calculate the tone difference and put a slight blue filter in front of the Arsat lens. This, of course, if you plan to watch the slides projected. If instead you plan to scan them, you can easily edit the white balance in photoshop.

The air quality is simply as good as it gets in these mountains. They are washed out often with the rain, and the clean air coming off the Pacific Ocean really helps a lot.

You took the words out of my mind Orio! In fact, I was already
contemplating using the light blue filter that comes with the lens as
a replacement for the graduated ND filter slot currently filled with the
ND filter. There is also a yellow and red filter included.
I love to project my slides, so it will be useful indeed.

It's because we are two old film junkies  who are used to think in these terms.
Photographers grown with digital would probably think that a blue filter is a new fancy type of cigarettes
