I was walking through a woods trail last week when an older gentleman walking the other way noticed the K-7 hanging around my neck. "A Pentax!", he exclaimed, "I have one of those!"
Turns out he bought a brand new Spotmatic in Hong Kong back in 1969 (so it doesn't say Honeywell on it). He stopped using it 2 decades ago because the meter stopped functioning and he couldn't afford to get it fixed.
Of course, I asked what lenses he had. He wasn't sure, mentioned he had "some 50mm and some 135mm", but couldn't be sure exactly which ones. I expressed interest in having a look at them and maybe purchasing them, so he offered to bring me the whole kit next week.
Fast forward to today, and the gentleman was at the same place with his whole kit. Turns out his 50mm is a Super-Takumar 50mm F1.4. It's in MINT condition, not a speck of dust anywhere. Aside from the yellowed glass, it looks like it just came out of the original packaging. The 135mm is a less interesting Soligor F2.8, but it's also mint. Build quality is outstanding, a true relic from the past. He also brought a Soligor 3x teleconverter, close-up and skylight filters for the 50mm lens, an ancient Vivitar electronic flash (with crazy side-mount bracket), and ALL the original documentation for ALL of these products, perfectly preserved in a plastic sleeve. Oh, and the Spotmatic camera of course, with a half-used roll of film in it.
I was mostly interested in the Super-Takumar 50mm, but it seemed silly to take that away from him and leave him with the rest. I ended up walking away with the whole kit (minus his bag) for $60.
I'd planned for this possible purchase, so I had already acquired the proper M42 adapter for my K-7 and was able to try out the 50mm lens right away. In a word; wow! I can't believe how much light this thing captures! It's really impressive, I feel like I don't need a flash anymore. After taking a couple of shots, I put the lens under a black light for a few hours and it seemed to get rid of most of the yellowing. It's not a UV light though, so I'll have to put it in direct sunlight whenever it deigns to show itself again... it's been a few days since I've seen the sun.
The 135mm did not yellow noticeably. The glass is still crystal-clear. It also doesn't have a speck of dust on it. The pictures with it are a lot better than I expected. Even though it's the same aperture as my DA* 50-135mm, I find that the Soligor 135mm is faster. Maybe it's the lack of lens coating, thereby allowing more light through. I'd say the Soligor lets in almost a full stop more light (maybe 2/3 of a stop?)
The 3x teleconverter is everything I thought it would be... it kills about 3-4 stops of light, makes the picture quality drop like a rock, and makes for a MASSIVE magnification when combined with a 135mm lens and an APS-C sensor (equivalent to 608mm on 35mm camera). I'm still not sure if I wouldn't get a better picture by cropping out a 135mm shot, I'll have to do some tests. In any case, it's really hard to get a sharp shot at that focal length. Even sitting on a tripod, the picture in Live View was bouncing around all over the place. The 3-4 stops of lost light don't help. And focusing manually at that focal length is a nightmare because I can't keep the camera steady enough.
I had to take a peek through the viewfinder of the Spotmatic... what an AWESOME view!!! It's huge and bright and the micro-prism focusing circle is brilliant! I wish I had one of those on my K-7...
All in all, I think this was a very worthwhile purchase for $60. I've been wanting a fast 50mm since I bought the camera, and I feel like I lucked out with this particular example of a fine lens. The rest of the stuff is jut icing on the cake. Oh, and the film camera might be fun to play with too
It doesn't have a working meter, but everything else works flawlessly.
(there's dust on the surface of the lens in this picture because of the damn dogs in the house)
