Camera conundrum

So I’ve talked about (and shared pictures from) my handy-dandy Pentax K-1000 here a lot.

It is my go-to camera, and I’ve owned it for near on … gulp … forty years.

I love it, and I’m happy with it.

But my dad also has a camera.

Well, had. He gave it to me a few years ago because he doesn’t use it any more.

It’s a Canon AE-1 Program. With a 35-70mm lens.

It works. It’s OK. And apparently, it’s fairly highly regarded in the film camera community.

Well, in some circles, anyway.

So the question I now find myself facing is this:

Do I buy a 50mm prime lens for this camera? For under $100 bucks?

Or do I buy a different, more expensive lens for it that compliments rather than overlaps my set of Pentax lens?

Or do I just shove it in a dark corner and stop spending money willy nilly on camera stuff?

(And save that money for a Fujifilm 690 or Leicaflex SL2 or Mamiya C330 or Hasselblad 500 or …?)

And that, my friends, is Great Acquisition Syndrome in a nutshell.

May God have mercy on my soul.
