Wow! If I found that lens for "the price is right" of $25 and then sold it east for $5000 I would feel really bad for the person at the flea market who let it go so naive. I would probably return to that vendor and figure out some way to get that person a 10% finder's fee either through more purchases or a one time gratuitous donation. |
yeah, have been thinking about that.. he has camera stuff pretty often but generally doesnt know or care what any of it is, so the prices are always about the same ($25 if its beat up, $40 if it isnt, etc... ) this one is a bit worn out and not in great shape (slow aperture due to oil on blades probably, some haze and fungus or separation around the edges of the rear element), question now is do i clean it up as best i can without disassembly, send it off to be CLA'd (who could i possibly trust with that?), and/or try to sell it? wife of course wants me to sell it :/
ALPA to NEX adapter arrives in a few days, will at least try shooting with it before i make any decisions |

Don't you have a decent camera repair shop close by? I guess servicing of this lens can't be to complicated. Only haze or separation could be a problem, but maybe they can at least give their opinion by taking a thorough look at it. |

camera shops in general, much less repair shops, barely exist in the US anymore, and those that had managed to hang on seem to have closed during the pandemic. |

I've seen the Minolta Chiyoko 5cm F2 shown as a 7 element in 4 group design, like the Summitar AND I've seen it shown as a 7 element in 6 group design. Judging by a quick look and count of reflections holding the two lenses side-by-side, I think the answer is Yes, Both are correct- the design changed.
This weekend I should have some time to open it up. |

It is in 39mm Leica mount, this is my 9th Minolta Chiyoko lens in Leica Mount.
This series of lenses is very good. The 5cm f2 lens gives the closest rendition of a Summitar that I've seen. |

Well this lead to me fixing the softness in my plastic copy. It turned out someone had reversed the rear element.
Images looked like this:

And now like this:

I added 3 more yesterday during an unexpected trip into town.
Exaktar 55/1.7 in M42 mount (which came with a Exakta TL1000)

& an Aicomatic 135/2.8 also in M42
All look to be in excellent shape but the camera does need a battery.

The front Section of the early Minolta Chiyoko 5cm F2. I got it cheap ($140 with shipping) due to some internal haze and fog. I was able to open it up and clean most of the haze and fog out. Remaining coating damage on the surface behind the aperture is slight, and at the very edge of the optical path.
The front "group" is in a fixture. Remove the name ring, use a suction cup to pull out. Remove the front retaining ring, and the "group" comes out as a whole. Looking at it close- looked like a cemented pair. Then discovered that it is an "Air-Spaced" doublet as some books call it, or two separate elements as others refer to it. There is a small "shim" for the edge of the elements that sets the spacing and also held them together. This is often defined as an air-spaced group. An optical "group" in a lens can be air-spaced, oil-spaced, or cemented- as further reading indicates. I used oil to repair a Sonnar formula Canon 135/3.5, it eliminates Newton's rings. The spacer in the Minolta "Group" eliminates Newton's Rings. Oil and air-spaced groups eliminates problems with thermal expansion being different with types of glass used in a group.
This is not one of the easier lenses to work on- required suction cups and some prying to get the fixtures out of the barrel. The front most element- once separated, is very thin. You could easily crack this lens when reinserting into the fixture. Make sure it is all the way in, and placed evenly before screwing the retaining ring back on.
SO: NOT the same as the 7/4 Summitar which uses cemented groups. Closer to the 7/5 early Summicrons?
ANYWAY: mystery solved for me, and the lens is in much better condition than when received. Gives me an early and late version of this lens.

Thankyou!
This is an early ome, I believe the 127th made.
This is the element with haze- mostly cleared off.
And- a test on the Leica M8, I am happy with the results.
Both wide-open.
Not the same formula- but the closest rendering to a Summitar that I've seen. The coating of this early lens is much different from my later 5cm F2 Super-Rokkor, 43mm filter size. This early one uses 40.5mm filters. |

NIce small and lightweight wideangle lens! Seems to have the same optical formula as the earlier Mamiya Sekor CS 2.8/28mm.
I have several copies of the Sekor CS, but only one of the Sekor E 2.8/28mm. Sadly the latter obviously is defective, even though it looks pristine from outside ... I had gotten it for free from a retired photo dealer - it seems the lens had been sitting in drawer for ages, and I guess the original owner had brought it back to the shop because it was "substandard" ... _________________ www.artaphot.ch |
