Erik, I'm going to counter
part of Nick's analysis, but only part of it. I do agree that the Pentax z/pz70 is not a good representation of what Pentax film cameras can do or why they are celebrated. What you get out of what you bought, in terms of value, is going to be partly down to your expectations and experience (and, of course, whether or not what you purchased actually works as it should).
The z70 and pz70 are the epitome of Pentax's era of trying to be like Canon. That said, I have a z70 (not pz) that I love. That's even despite the PIA batteries and the DX-only ASA coding (the latter of which you can easily work around). I typically have to order my batteries online because I can't find them locally and it takes a long time to get them because they aren't shipped by air to Ireland (lithium). But, I tend to get about ten rolls to a battery while using autofocus and a little bit of the on-board flash, so it's not terrible. Most of the film I use is Ilford B&W with DX coding, so it's not a problem. I regularly use my z70 with Pentax film-era AF lenses and
also the DA 35 f2.4, DA 50 f1.8 and DA 10-17 fisheye (from ~12 mm to 17 mm) with great results and also with PKA primes. I particularly enjoy using the SMC PKA 28 f/2.8 on the beast at f/8 on the street because it works so well pre-focused. My z70's autofocus performance with wide-aperture AF glass is quite impressive, in fact.
I also have a Sigma UC 28-70. Mine is not AF and is in MD mount, but it has served me well for nearly 30 years on both film and digital bodies. I believe your UC 28-70 has the same optics.
I still use it today on my 20 MP mirrorless with great results. Optically, it's a fine lens, mechanically...not so much. I can't speak to the quality of the 60-300 you bought. It may be fine or something to avoid.
So, overall, what you bought is not necessarily terrible in terms of value
as an experiment with film photography (assuming everything works), but it's
not representative of what Pentax's film cameras are really like. For that, you will have to do as Nick suggests and find a K or M series manual focus body and some K or M glass to go with it.
In the meantime, find some batteries, load up some film, and see what happens from there. If you like working with film, the rest will follow naturally.
