Agreed. I still use my 55, manual 105 and once in a while the 200 micros. They are old and continue to work as when they were new. Darn good service life.

If you had stayed with Pentax, you wouldn’t have needed to change mount systems even once, wouldn’t have needed to learn anything about Canon. I use exactly the same lenses on my current Pentax that I use on my “Spotmatic”.

PS, Spotmatic lenses can easily be adapted to Canon EF and Canon R cameras using a similar adapter you had to get for the K bodies. K lenses also adapted to the Canon EF and R bodies as well.

but Pentax K-mount bodies are what I have now; I gave up on Canon Rebels.

That is absolutely fine.
Nothing against Pentax.
Just that I find it interesting the M49 lens reference on the K bodies. Where those same lenses adapt to Canon bodies as well.

Pentax went smoothly from M42-mount to K-mount, and today M42-mount {the mount actually used for “Spotmatic”} is as likely to be identified with Pentax or Practika as anything else.

You are correct, M42.
Mixed it with the m39.
I thought it was a good move at the time going to K mount and saw thousands of K1000 (I believe) sold to students for college photo classes. Well built and great little camera.

Ps
ALL Canon EF, EF-S, FD, FL, R and M39 lenses work manually as the older manual lenses did and the newer EF and EF-S from 1987 to present work 100%as designed but with enhanced features similar to RF lenses on R bodies.
So they ALL work on modern digital bodies dating back to the 1950s.
So no issue with Canon products and compatibility on even the latest digital bodies that is missing with the Nikon products on the latest Nikon digital bodies.

Canon did "make all things whole again" with the R bodies. But the 1987 break away from FD/FL lenses to EOS and the EF lenses did piss off a lot of folks who had a substantial investment in the FD/FL lenses.

Nikon has a maze of gotchas to navigate with its many variations on the F______G mount, what with no prongs, metering prongs, metering prongs plus AI, screw drive body motor AF, in-lens AF, etc. You need a compatibility chart when you buy lenses to learn what fits, fits with caveats, and won't fit.

There is a point where maintaining compatibility with the past is more trouble than it is worth. Canon made that painful break, and it has made a huge difference in their long run of success. Fortunately, the shift to shorter flange-to-sensor distances with mirrorless allowed adapters to work well for most brands. It has even enabled brand switching without pain in a few notable instances.

It's a nice macro lens...check for fungus.

I still use a few of the non ai lenses ...they have a look to them...tend to be on the cool side.

That lens is available around the usual places...can pick up a great copy for around $100.

Even today some Pentaxians ask for a “digital K1000”, although it is not clear what they are looking for. Incidentally, eventually K1000 construction was moved to China, and it ended only about the time digital became regular. Every once-in-a-while there are rumors that some Chinese company will resurrect the K1000. I have never owned one, thinking it was too “clunky” when I purchased my first Pentax in 1979

I have a few. Never paid for them. They were OK when they were $99 and the next up in the line up was about $200 for the body. But now they are sold used for more than those higher end models. Makes no sense to me. And I said I have a few but I never used anyone of them. They are built like a tank due to their crudeness not toughness.

Thank you for your input. Since I have a D70s. D90, and a D7200, a D7500 may be in the picture soon.

Even though your lens will mount on the D7500, you will get no metering through the camera. There will be no mechanical or electronic connection between the lens and camera. I don't know enough about the features of the D7500 to know if you can use external metering and set up the camera in the manual mode.

There won't be be metering and thus no meter it only works in M mode. You can indeed use external meter and set the camera up in manual. The camera does have the aperture stop down level to stop the lens down to set aperture during the exposure. No coupling for the aperture so the camera doesn't know which aperture you set.
