The Super Multi Coated Takumar lenses seem to get a lot of attention, but I was searching around the net and it seems that the Mamiya/Sekor 55mm, 1:1.8 is pretty good as well. Last summer, I found a broken 1000DTL at a flea market for 50 cents and I just got around to attempting a repair. The second shutter curtain doesn't close, so it looks like the repair may be beyond my abilities. The good news is, I got the aperture blades freed up, so, at least I got a good lens out of it. I also have a Super-Multi-Coated Takumar 50mm 1:1.4, and a Cosinon 50mm 1:1.8. I plan to try all of them out on my Pentax SPII. Does any one have opinions on these lenses as they compare to one another?

The only Mamiya SLR that I've used was a ZE-X with a nice variety of Mamiya lenses. They were outstanding lenses, and I regret ever having gotten rid of them.

The Takumar should be excellent, I find them sharp but lowish contrast as a rule. Easily fixed in PP or the darkroom. The Mamiya's have a good reputation as well, so that is worth keeping and trying. The Cosinon ? they have a mixed reputation, I had a 2.8 28 for a while and found it didn't perform as well as my other 28's and 30's so off it went. But since then I've read that some people love it. Perhaps there was more variation in the quality of the cheaper Cosinon ?

All to do with price, Mamiya and Pentax were about the same quality, but as a top maker Pentax offered two ranges, basic and up market options, whereas Mamiya mainly did one range. Cosina did make their own lenses and at the price were good performers, but very much with budget pricing in mind. They built for other sellers as well, and made for Vivitar etc., at times. Stephen.

On the shutter, it is a pretty standard Leica type internally, with non rotating dial, so the adjusters should be obvious inside, I would expect underneath. But if the second shutter is running and not closing, check there is no fouling of the leading edge, by frame masking etc or even broken film shards. It may be the tapes have come adrift, an easy but long winded job to re-glue. But Mamiya are well built indeed, and it is more likely damage than wear and tear. Stephen

I can wind the camera and when I press the shutter, the first curtain opens, but the second curtain doesn't move. Also, the mirror stays against the focus screen. The mirror is being held up by the mechanism and not stuck by old foam, since I can pull it down against spring pressure. I am guessing that the second curtain has come loose from the tapes. I found some tear down instructions on Ron's Mamiya site, so I'll give it a go. If it doesn't work out, I'm only out my time.

That sounds very like the tapes have come unglued, a quite deep service, but Mamiya are well made, and I doubt if you even need new tapes, just the glue may have failed. Stephen

I had a Mamiya 1000TL with the f/1.8 lens (when they were the newest thing around. The lens way decent. I think it was probably comparable to the Takumar normal lenses from the same period. With all cameras of that period the slower "normal" lenses (f/2, f/1.8) tended to be better overall preformers than the f/1.4s.
