Thanks. I may attempt a repair myself, if I can get one that is working. Otherwise I will pay to have someone else work on it. :-)
Yep, I have a working model on it's way to me now. I will likely rip into the broken one after I shoot a few rolls through a working one.

I'm a fan of Retinas as well; actually the 2.8 lens can be more contrasty than the 2.0. Comparing to other cameras of the same era and general purpose, the Retinas are well thought out and have better lenses than most of the competition. About the only sharper lens is the f/2 Solagon on the Agfa/ANSCO Super Memar. But that lens has its own character, emphasizing sharpness over other rendering, so maybe not as balanced as the Retina lenses.
I had not heard of the Memar, but checking your Flicker site, see why I thought it was an Agfa Silette of some type. Looks as if it's 6 element lens is the competition for the Xenon. You make an interesting comment about the f2.8 vs f2.0. lenses. I have Retinas with the f2.8 Xenar, 2.8 Xenon and f2.0 Xenon. If there are differences in results, I have trouble seeing them. Gut feeling tells me that 6 lenses may not be useful with a f2.8 aperture, but have benefits of correction with F2.0 and wider. Do you think the Xenon at f2.8 has any advantage over the Xenar f2.8 lens? My thoughts are that if corrections are not needed at f2.8, the extra glass just becomes a source of reflections - which supports your comment about contrast differences.

I can't comment on the Xenar - not having tried one - but as much as I love(d) my IIa Xenon f/2, when I compare results the 2.8 Xenon is consistently sharper seeming - whether that's due to a 3 or 4 year age difference in lens coatings, or indeed that the 2.8 is easier to correct.



IIc with 2.8 Xenon



IIa with 2.0 Xenon

But the light bloom is fun to play with

+1 on the Xenons. The 50mm f/1.9 Retina-Xenon found on the later Deckel mount bodies is one of my favorite lenses of all time, and I frequently use it with an adapter on my K3. The 50mm f/2.8 Deckel Retina Xenar is no slouch either, and quite a bit smaller than the Xenar, but is jjust missing something in its rendering that the Xenon has.

Truth be told, I don't know if I've ever used the "S" setting on my 90/2.8LS except by accident. (Which I'd discover due to blank frames on the roll. ) It's a very specialized setting, and I'm guessing it wasn't a popular one; the 165/4LS doesn't have it, from what I recall.
I've only used the "S" setting a couple times for taking double exposures with the 6x7 Tak 90/2.8LS. The issue is the viewfinder is blacked out after you press the camera shutter button, so you have to compose the 2nd (or 3rd, 4th and so on) shots "blind". You trip the LS with a cable release attached to the lens.

Not the best setup, but it does work. Yes the newer 165/4 LS does not have this feature.

That kitty is very appealing.

Before modern lens coatings, pioneered I believe by the SMC Takumars, adding lens elements usually meant reducing constrast which contributes to the perception of "sharpness." Most really good f2.8 normal lenses were four element Tessar-formula or close to Tessar configurations, the Tessar formula being one of the truly great breakthroughs in lens design. To get one more stop, f2, 1.9, 1.8 generally means at least 6 lenses, and as noted above, that adds additional reflecting surfaces = inevitable contrast and image degradation. Pushing physical limitations - larger aperture, wider wide angle, longer zoom range - almost always comes with some loss of IQ although modern coatings, ed glass and aspheric surfaces have allowed multiple focal lengths to achieve f1.4 with IQ that matches or surpasses the best Tessars of the past.

Old standby (left) and newly acquired older brother (right):



The Mirar lens on the Flexaret IIa is a triplet, which makes me strongly suspect that the Belar on the Va is probably a Tessar-type.
There's a significant difference in weight between the two, which isn't surprising as the Va has far more complex machinery inside it. Though the IIa is also light even compared to my Yashicaflex, which is similar in functionality.

(I'm not actually using 400 speed film in these, but it seemed fitting to throw it on the table with them.)

+1.

In medium format, a triplet can beat a 4 element lens...

A new accessory for the Yashica Mat 124G thanks to my thrift store ... a cased "YASHINON AUX WIDEANGLE" with viewer lens.


Picked up the wide-angle plus a quite nice working Olympus 35 RC and case for 2 each ... see the "2" on top of camera. Bastards ...

I am going to a swap in Nantes on Sunday and I will try to trade away the left Mat G ... but, keeping the wide angle set, hood and hard case set

I know, right? It seems such a shame to ruin such a nice camera, by using a felt marker on the sticker. Sigh.
You should send that to me, I could live with that. :-)

Sometimes felt marker writing can be removed by gentle, persistent rubbing with alcohol.

I got the marked "2" off thanks to my trusty Scotch "Easy Clean Pen" ... works great.

Once after I gently and persistently rubbed my insides with alcohol I woke up with felt marker writing on me.
