I have been lucky enough to score this lens.
After my experience with my son's 100mm Isconar I am keen to see how good this can be.
Is it a triplet like the Isconar?
Or some other design?
Cheers
OH

Yes it does Mo. The glass looks good in the one shot that shows it, but the body has taken a pounding.
I just goes to show what bidders are looking for in a lens. This grubby example attracted little interest.
I'm sure if it had've looked like the example that Calvin posted it would have attracted many more bids.
It is on its way - I will post some images here when it arrives. Could be a week or two from Europe.

OK, lens has arrived and I was keen to see what it could do.
Lots of aperture blades - 16 I think - so nice round highlights.
Here are some samples

I am quite pleased with this lens.
If there ever was a great example of "...... never judge a book by its cover ..." this might be it.
The lens has been well used as evidenced by its exterior.
But the glass is outstanding - and the aperture lovely.
Here are some pictures of the lens itself.

Thank you.
It embarrasses me to say EUR 12.00.
No one wanted such a ratty looking lens.
Got lucky I think

I prefer the war torn looking lenses, as long as the optics are good.

Apologies for resurrecting an old thread.
Is the Isco 180mm f/4 really around 660 grams? I see these on eBay regularly but have never pulled the trigger on one yet because of the weight. For various reasons my limit is about 500 grams. But these lens would be right up my alley.
Regards, C. |

Looking at the pics on this thread and the linked ones just convinced me to make an offer on a fixer one one of these.
To anyone who has one, can you confirm that the exterior is plain black anodizing as it appears, and not overpainted? The one I made an offer on is rather worn, too, and it might be a nice candidate for a refinish. |

Not a problem, as I am equipped to recement elements. Just did three doublets today, as a matter of fact! |

It's not as intimidating as it looks, although now that methylene chloride strippers have been banned in the U.S., I typically have to use heat to separate lenses using synthetic adhesives, which is a little dicier. Older doublets using Canada Balsam separate easily with regular acetone. The cementing itself is fairly straightforward using NOA61 UV cure cement. The Isco should be here Monday. If it requires recementing, I'll add photos of the steps to this thread.
The Septon in theory should be easy to separate/recement, as the doublet is quite small, but I've never actually been able to successfully remove the retaining ring holding it into its housing. I actually have 4 of these lying around with varying degrees of separation awaiting my figuring out whether it's feasible or not.
Many unsuccessful attempts led me to believe the doublet that typically has separation (rear of the front cell) was permanently swaged in, but this guy in China seems to have successfully removed and repaired it. I once reached out to him using Google translate to see if he could let me know whether he lathed it out or successfully unscrewed it, but he never got back to me.

Just out of curiosity, have you ever repaired a Steinheil Quinar 135 2.8? Not the black Auto version but the silver preset version?
I got one in pretty bad condition and managed to fully repair it except for the rear optical block, which I could never figure out how to remove. If I could get it off I could get rid of some grime on the inner elements. |
