Can anyone recommend a solidly built Pentax K to Sony E adapter with a tripod mount? I need just a basic, "dumb" adapter to use my manual PK lenses on my Sony A7ii. But it must also have a tripod mount included.

My current adapter has a tripod mount, but I don't trust its build when using heavy lenses. The tripod foot can be removed from the adapter, which is convenient at times, but the connection between them isn't as secure as I'd like.
This is what I have now:




And the ones I see on ebay don't look much better. Such as this:
Pentax K PK Lens to SONY NEX E Mount Adapter with Tripod 1/4" Mount NEX-7 5 3 | eBay

Solid but expensive solution: Novoflex Pentax-K to Sony-E lens adapter:
Adapterfinder Products
with ASTAT-NEX tripod collar:

If you can do without removing the foot, maybe some thread lock will make it more secure.

If it is a heavy lens it would be more suitable to put the tripod mount on the lens.
Maybe you can find a generic tripod mount for the lens?

Or a tripod mount like Manfrotto 293 that holds both the camera and lens.
So you can mont the tripod to get perfect balance between lens and camera.

Ah, I should've guessed Novoflex would have something like that. I knew they had an adapter, but I hadn't seen their tripod mount. Beautiful but, yes, probably too expensive for me.

Of course! I should've thought of that. Simple, cheap and probably effective.

Yes, good thinking. The lenses I have in mind are the Samyang 135 f/2, Pentax K 200 f/2.5, Pentax M* 300 f/4 and various old, long zooms. Since I'm mostly a casual snapshooter, the Manfrotto 293 is probably more than I need. But adding a generic mount to my adapter might be an improvement. I'll think about that.

Thanks to all for the helpful suggestions!

Thanks, jlstrawman. I think I'm going to first try thread lock on my existing adapter. And if that doesn't work, then I'll start looking at alternatives.
