I'm hoping the Pentax Kit lenses with zoom are permitted (provided they are within the focal length of the category, that is...)
if so, here is my entry for "Something Special About That Lens"...
Having so many sub-35mm lenses, my favorite of all time is my SMC-M 24mm. But, with that one having a sticky vane problem, which I have not been able to cure yet, (and now having a FF K-1) my go to, at the moment, is my HD Pentax-DFA 28-105mm.
Here is an image using this lens at 34mm, at night with lots of pinpoint lights in the image.
I like this lens because of how fine and how many, those flares are, due to the aperture blades.
This "Fraunhofer diffraction" effect makes a perfect texture effect, for me, and I think, really enhances the image...
So here are the Stats:
