I found this on Marketplace. Would this lens work for a Pentax K1000? I’m trying to build a decent collection of lenses, and I don’t have one that shoots this range yet.

We have a back door that swings outward onto a raised porch. Now, before you come at me that the door was hung the wrong way, it wasn’t. There wasn’t room inside for the door to swing fully open on the inside, so we did it this way.
My question is about screen doors. We like to open the door at times for ventilation, but want to keep bugs out and our cat in.
I see a few different models of retractable screen doors that are supposed to fill this need. Has anyone in the Redditverse installed one? If so, Which one and how well does it work?
