Old Bayonet mounted lenses

I have an old, film, ME Super with several bayonet-mount, manual lenses. I would like to replace this with an equivalent DSLR, but, after reading several of the posts, I am still confused about which will work. None of these lenses have an "A", all have a manual F-stop and focus. Can someone simplify things with:
1. Which model Pentax body should I buy?
2. Will I need a lens adapter ring? If yes, what model?
3. Am I doomed and should I just buy a new DSLR and start over? I really like my 135mm portrait and 500mm lenses.

There's really no need for confusion. If the lenses are Pentax mount, the will work on any Pentax DSLR. If they are screw mount you will need and adapter, but if they are, as you say, bayonet mount then no adapter is needed.

Welcome to the forum Jay! No, you won't need an adapter to use any K mount lens on any Pentax digital body. Those older lenses have a huge following here on PF. Search the forum for using the aperture ring on a digital body. Which body to buy is determined more by your budget. There are also many used bodies and lenses in the Marketplace. I started with a K10D and then moved on to a K20D, a K-5, and now a K-3. I've also seen some good images here on PF from the K-30 and K-50. I hope I've been helpful and look forward to seeing your images.

Any of the current Pentax dSLR line will have feature sets that are much beyond your ME Super. In my opinion the K-50 is probably the best value.

Jay, I started out with a K-1000, and made the jump to digital when I bought my K-30. I love the camera. The manual lenses are marvelous with it, once you figure out the buttons and settings.

I did feel a bit let down when they introduced the K-50 so very soon after the K-30, but have not felt compelled to "upgrade"...the K-30 was a comfortable choice and I'm glad i bought it. From what I've seen, you can get a K-30 body only for as low as about $300 on the Marketplace here...a fact that (having bought mine new in January of last year) kinda makes me cringe at what I paid for mine!

But as a first digital camera, I'm glad I chose the K-30. And that 18-135 kit lens is no slouch, either...although it did contribute to me putting off turning that dial away from "AUTO" for a longer time than it should have!

And you've found the right place to ask questions...wondrously helpful and friendly folk abound!

The K-30 and K-50 are pretty much identical. I have a K-50 that I use old lenses on almost exclusively. The M and A lenses are too good to pass up.

k-30 if you're buying used and find one for under $350, k-50 if you're buying new (unless you find a new k-30 for significantly less).

Your favorite lenses are going to be cropped so they shoot like:
135mm=200mm
500mm=750mm

Really, just remember the lenses won't give you the same field of view on the new DSLR, that's all. A 50mm on your film body will "look" more like a 70ish mm on an APS-C body. That's all - you may find yourself wanting something on the wider end.

You'll want a body with two control wheels, making it easier to control your settings.
Also consider buying a camera with the focus screen swapped for a split-focus screen or installing one yourself. I had one on my K10 and it does make manual focusing much easier.

Beyond that, any of the cameras will work for you. A K30 is a good value, but so are used K5s. There are also threads about the focus screens, you'll find them.

Be mindful that the lenses you want to use don't have the Ricoh pin problem.
