Shooting my CZJ (postwar) 2.8/50mm results in distinctively cateye-shaped bokeh towards the corners.
Plus the overal image suggests a much longer focal length than 50mm.
Just my 2 cents.

Indeed. I have always loved the Pancolar and Sonnar, but never understood the common, utter love of the Flektogon. I have tried three copies (never in a controlled, scientific way) and I just don't see it as such a great performer/lens. |

I see your point, I will ask her. Maybe a crop, or small sensor camera?
Anyways, my zebra version doesn't have perfect balls on a FF camera. But I wouldn't call the corner bokeh distinctively cateye-shaped: Maybe there's a difference between different versions?

Looks in good condition. You'll need to see if you can find the 52/3.5 lens, the first MF retrofocus lens made with a 35mm (equivalent) 28mm F/1.9 field of view. |

I don't use the CZJ 2.8/50mm Tessars often, so I'm not familiar with all their hidden secrets - bu i really was surprised to see a "Tessar" image with
1) completly round out-of-focus "balls" and
2) a lot (a lot!) of bubble bokeh
When I shoot the Tessar on FF cameras, the bokeh looks more like yours ... plus distincive cateye shaped structures towards the corners.

I've already read about it. They are still too expensive on Ebay. |

How does the Fujita compare to the old Kowa 66? Looks quite similar.

My first Tomioka lens , it's amazing how beautiful is, probably original silky smooth grease and nice metal feeling all over the body, unfortunately no original front cap, but it came with the leather case (was there an original good?)

Even though it's a taking lens (and I'm mainly focusing on industrial lenses) it will be featured in my upcoming article on Tomioka to a significant extent.

This tomioka ,on wide open has the blades visible (blades don't open all the way) I wonder how visible would they be on the bokeh balls? |

Took a chance on this (ebay pics):
It took more than a month to arrive after taking a magical mystery tour of the USA, eventually making it's way to the UK and landing on my doorstep late last night wrapped in a couple of padded envelopes, it's soft case and a couple of socks. I was expecting it to be in rough shape anyway and the packaging didn't inspire confidence that the journey would've helped the situation.
Anyway, after bringing it inside and giving it a chance to warm-up a bit, I tentatively cut open the package and was quite pleasantly surprised; not perfect but better than expected. So far so good.
How's the focus? Stuck hard with the lens fully extended. Got that to move - still very stiff but not totally seized.
Glass is dirty, particularly the rear element with a layer of greasy looking dust. How to get in there? Well, the whole optical block and aperture mechanism unscrews from the focus helicoid so I popped-out the element and cleaned it. Unscrewed quite easily so someone's already been in there. Reassembled it with the freshly cleaned element looking good. Time for a quick test shot to see what I'm working with:
Oh dear! That's the sharpest it could manage. Maybe the rear element's in backwards? Tried reversing it and that just made it even worse. Put it back the way it was, concave surface out, which seems correct?
Discovered the front part, just ahead of the preset ring, unscrews and found this:
OK. The large cemented group is jammed-in at an angle and it's retaining ring is left just hanging-out on top of the aperture. Great! And the glass is really stuck in there. Wrestled with it for a while and it eventually broke loose leaving even more of the damaged edge-blackening on my hands. But the glass seems in decent shape so fished-out the retaining ring and put it back together. Time for another test shot:

Not too bad really. It could've been so much worse!
Focus is still incredibly stiff and the edge-blacking needs sorting out (any suggestions welcome) but it's got potential. |

I was actually looking for the mf version, but the supply is so minimal that i finally settled for the af version. The Sigma 180/5.6 apo. It has Min AF mount for which i have a (manual adapter).
It comes from Japan, and from the description it has some fungus on the rear element. On the pictures it looked minimally though. Let’s hope for the best: probably I have to wash off the horrible coating Sigma used on their lens barrels those days that becomes sticky when it gets old. |

One of those crazy early retrofocus designs with a small master lens, lots of empty space and a huge negative front element. It has a unique rendering typical for those early retrofocus lenses, plus a pretty good correction of CAs. Could be very nice for reportage at low light. Low contrast and relatively much detail.

Wiping down the ground glass with acetone will take the existing blacking off.
If they sell them in the UK, then get a Sharpie oil-based paint pen (not the regular Sharpie marker), and redo the blacking with it. It works extremely well for this purpose and dries fast:

I've had a few examples of this lens. The semi-auto aperture and rather slow focusing action don't make it the best for such an application, but it's a great landscape, nature, and architecture lens. The version with the half stops is probably a little more useful. Can't tell from the pics here, but identifiable by white dot markers on the half stop positions on the aperture ring. Significantly more of a pain to service than the later full auto Taks, but very well built.
