That's about the time ('69-'70) my Dad bought his Spotmatic, with a 50/1.4, a 135/3.5 and some other bits and bobs,
I have it in a showcase now, with other film gear, but it all still works,
It seems cheap now, but he was a Captain or Major coming back from his last tour of Vietnam, with a wife, two kids and a mortgage waiting for him, when he picked up this kit, I was about 10. This was not a small purchase in that day and age.

If memory serves, this bellows should have a cable release socket on the lens board, when an auto aperture lens fitted, the double ended cable release that came with the original kit would have stopped down the lens and fired the shutter with one push. Hence, Auto!
Looks like that lens is a preset, (the double aperture rings gives it away), so no auto stop down with it.
Looks like a fun bit of kit to play with,

both Blue Angels and Thunderbirds each flew the F-4s for a brief period. The story I heard as to why the BAs went to A-4s and the TBs went to T-38s was fuel. The F-4 was a much more expensive aircraft to operate. Late '60s early '70s was the first of the fuel crises,

APS-C Macro Lens

The Pentax 100mm macro is great for both FF and APSc, the extra working distance you get for true macro is very useful.
While the 35 macro is a fine lens, at 1:1 there is no working distance, you are constantly fighting your own shadow in the frame (the voice of experience here).
For me, even a 50mm has too short of a working distance.

do you have any other lenses already? For an inexpensive start into closer work, you may consider option, such as macro "filters" that screw onto the front and allow you closer focus, a set of 3 that can be stacked can usually be found inexpensively.

Extension tubes can be a good entry point too.
For both of these options, I'd recommend a prime lens rather than a zoom though.

The EXIF data on your image indicates it was taken with a Pentax 18-135, at 135, not a sigma,

When I was at NASA Dryden, about 1992, we had a Kodak/Nikon hybrid digital camera on loan for a few months,
Was an F3 body, with a big battery pack/processor similar, but larger, to the standard Nikon motor drive hanging off it, a big heavy cable (about as big around as your thumb) came out of it, and went to another battery pack/hard drive that hung off your shoulder. The imaging chip was smaller than APSc; I think I remember we needed a 15mm lens for near normal (50mm) coverage. I don't remember having a screen to review images on it, had to get back to a computer and download/review.
We played around with it, I don't remember getting much of quality out of it, took forever to get the image from the chip to the hard drive. Pretty sure it was a prototype, doubt there were very many copies of it made.
I don't see the configuration I remember in this Nikon white paper, but this seems to cover that early period about right.

If its any comfort, that close focus position looks like where mine goes to, right between the 3 and the 9
But the other end is certainly off, no infinity.

Short answer,
There is (currently) only one Pentax 18-135 lens
Mostly sold stand alone, but
They are sometimes bundled with bodies as a kit lens.

No offense taken, but I'm sure you could rile some up, similar to mixing up RAF and RN, Though they now have RAF pilots on the new carriers, Go figure!

Been a long time, been shooting just not taking the time to download and process, some highlights from the last month or so:

Unusual view of Rainier, looking almost due south, the lenticular is getting dragged off toward the SW by winds out of Canada. Usually the wind out of the NE is drier, and we don't get the clouds forming off it.

Walking off the ferry one morning in March, sensed the colors behind me and found a spot to get out of the other commuters and caught these clouds and colors, was very fleeting, Olympic Mountains under those rosy clouds.

Been working from home the last two weeks, wife and I trying to get a little exercise in, Walked down to the old ferry landing at the road end, Found this "Tea Kettle" cloud, Wish there was a foreground for it.

Hope all are well in these strange times

Pretty neat colorization of old film footage - New York 1911

Thanks for finding and sharing,
Interesting stuff, not sure the added color adds much value,
That original film stock not doing well for flesh tones, and all the skin colors look quite dark. And it carries through in the colorization. Think some more effort could be done to try and tone down the contrast, so you see into shadows a bit more, there may not be that much to get out of that old footage though.

Watching the horse drawn carts getting off the ferry boat, imagining what the "car" deck on that ferry must have been like in the hot summer.

Was odd to realize those one legged men in a couple of the shots were likely Civil War vets.

tripod mount

Pretty sure there are only the two versions of the 50-500 "Bigma" the older non OS, (mine above) and the newer with OS and some other bells and whistles.
Mine has three white index marks; one top center for Horizontal, and two for vertical at both 3 and 9 o'clock
the "REMOVE" is just beyond the 9 o'clock position looking from the camera end (about 8 o'clock)
When looking at the front of the tripod mount ring, you should be able to see 4 notches spaced around the tripod mount ring, these align with the studs on the lens barrel, and allow the rotation and removal. The studs and notches are not evenly spaced, so there is only one location where the studs align with the notches and allows the ring to slide off.
If you are not getting any movement by loosening the knob, then something is wrong:
With the knob loose, you may want to try firmly but gently tapping or knocking the foot front or back to see if it's just bound.
At the foot, next to the knob is a gap where the clamp action happens, with the knob loose, you might try slipping a thin but stiff blade in there and gently twisting to open it a bit. It's all aluminum, so pretty soft and easy to mar or break, be gentle with your force. I hope it's not glued as Roger suggests, that would be a shame.

Lens hood; I'd recommend tracking one down; it's a big chunk of glass on the front. Will attract both sunlight and goopy fingers. It think lens hoods are as useful for physical protection as they are for flare protection. I've still got the original petal style hood, it bayonets on, 86mm front threads, so a similar size hood may work. Not sure if the newer lens takes the same size. You might try Sigma and see if they can provide direction on a hood for an older lens. Camera mount won't matter, front ends all the same.
Are you using with APSc or FF camera? less concerned about vignette with any hood on APSc, with FF you may need to test more carefully. Going with Sigma's recommended hood should be safe for either format.
Hope this helps,
Some photos of your lens might help us help you.

645z with Holga lens (yeah, I know. Indulge me)
Posted By K-Three

Any lens designed to work with APSC/35mm formats is going to have too short a flange distance to work at infinity with a larger format, you'd need to mount it inside the body of the 645 to get infinity focus. Mirror will be in the way.
There was a Holga 120 film camera with a very simple lens, you might try to find one cheap or free (Goodwill or other ?) and remove the lens from it and use an extension tube or other adaptor to get it onto the 645 body. Modified body caps can be useful to mount simple optics.

Good luck with it.

I always associated them with the M 50/1.7. That's what mine came with and they were packed with when I sold them new at Ritz camera. The K1000s were packed with the 50/2. I think by the time the M series was introduced, the ƒ/1.4 lenses were a premium and not sold with kits.

Because Photography has been a big part of both me and my wife's life and each of our family's before, we have a collection of cameras, which likely will never get used again, but mean something to us. I've been thinking about displaying them but could not bear the idea of them getting covered in dust. I've been talking about making something, but have not found the time or motivation to do that either.
Found this cabinet at Ikea, pretty much fits the bill, smallish footprint, and style wise fits the glass and metal theme of cameras.

Top shelf for Pentax; my LX, my Dad's Spotmatic, and my MX

Middle shelf for a Rollei and a Yashica TLR that my wife's family used, and a Konica my dad bought in the late '50s, and I used as my introduction to photography in the late '70s.

The bottom for my Linhof Technica IV and a Norwood Director meter that my wife acquired.

Can't afford to give up more floor space for another case, may add some more inside this one or rotate stuff in and out.

I remember sitting down with a Mac II FX (16MB of RAM!) in about 1991 with a 1.03 version of PS. It really was just a pixel editor back then, next to no undos, kept having to save a version every time you got a to point you were happy with it, and before you made the next major change.
Keep a copy of PS Elements on my machine to this day, only use about 10% of it, don't know what I'd do with the full version now.

Seems hard to believe it's 30 years old, but my marriage is 35 years this year, so maybe....
