Lousy pictures, but the second shows the better lens. Look at the fibres around the focus point..

shoot portraits of people (half length to 3/4 length) with the aperture wide open (f/2.4). take the same shot with your zoom.

He can't - his zoom won't go to f2.4 @ 35mm.

Not sure how you can equate spending $150 on a faster prime with changing systems or going full frame and spending $2000+.

That said, your images aren't the same, so it's hard to compare.

If you are shooting at f/8 most lenses look pretty good in the right lighting. You should see less aberration in a prime. Less. Fringing. Better contrast. And it should he a little sharper. Though, many zooms are equally sharp.

The big advantage of the prime is shooting wide open. You have a faster lens, and you have better depth of focus control.

Your 35mm is significantly faster and will allow you to grab some low light shots.

My fast normal is the FA 35MM f2. Love the ability to grab existing light shots. I wish Pentax made a 24 or 28mm f/2 that was as optically solid as that lens.

Sigma has some options, but I love that the FA 35mm is sharp at the edges wide open. It's a great lens.

that's exactly my point. For its size and weight, this lens provides a very decent subject seperation for environmentsl portraits.

OK - a little more experimentation and I'm understanding the virtues of this lens. This shot was taken inside a bowling alley at night. I never shoot ISO above 800 with my zoom (rarely above 400) because of the horrible image noise. I shot wide open at 3200 and 6400 and got shots I never could have with the zoom. So it's definitely a keeper lens for low light, indoor situations. I also want to try it on some HDR landscape photography that was the primary reason for upgrading.

I still don't understand why the reviews on the lens were primarily about sharpness of image (did anyone click on the link I provided and read them?) because as I stated originally I don't see a big improvement there. That's what I was asking about but most people who commented made observations about other factors some of which was helpful, some not.

The 18-55mm zoom is a very decent lens especially when shot at f/5.6-f/8.0. At these apertures, i doubt you can see a difference with the da 35mm except at the very corners of the image (Like taking a picture of a brick wall). Dxomark.com compares various pentax lenses mounted on different pentax bodies.

Here is a thread with over 50 pages that show what is possible with that lens: https://www.pentaxforums.com/forums/122-lens-clubs/196639-da35-f2-4-plastic-f...c-club-57.html
Seems decently sharp to me.
I think the reviews generally always mention this little part "for the price". It is a very good lens for that price point. Yes, something like FA 31mm will probably be better - but will also cost more. Or Sigma 35mm art or Zeiss 35mm or even Samyang 35mm or Pentax HD DA 35mm f2.8 limited.
Still, I have never found the DA 35mm to be soft. Especially if you look at the edges of the frame, the 35mm will have more detail and less CA than the kit lens. It will not be completely perfect, though. If you want that, get ready to spend $600+

Not sure how the lens limits noise. Noise is a factor of ISO, gain on the sensor sensitivity. So, if your noise is lower at 6400 than the kid lens, it's magic, not the lens. Or you got a magic lens, either way, be happy and create images.

I'm looking to increase quality and versatility without spending a ton of money. So this lens is definitely a good investment for me. Thanks for the feedback and links –I will check out Plastic Fantastic.
