keep them coming Brett. Very nice shots, very unique characters from those lenses. I learned a lot today from this thread (I read it from the beginning).
Thanks, I’m pleased some information has been useful. There isn’t a huge amount of detailed first hand information about the ALPA SLRs on the web in English. Some of what I have found has later proved to be not fully accurate. With a good cross section of different models from first to last on hand it seemed a good opportunity to examine them closely and perhaps de-mythologise them in the process.keep them coming Brett.

Welcome to Rangefinder Forum Stephen. Great to hear from another ALPA owner, especially an Alnea 7. I do indeed still have the relevant book by Lothar Thewes (I am keeping it), but am away from home for a few days (in Brisbane and the Gold Coast, actually), so please bear with me until I return home and can check for you.Hello from Brisbane (Australia) & my first post
Just thought I'd restart this thread as I've just sourced an Alpa Alnea 7 (serial #33219 (55-56?) with a Kern Switar 50mm f1.8 lens (non macro, serial # 383104). It's in quite decent shape IMHO, the shutter curtains are in excellent condition but the rangefinder window is quite hazy. The rangefinder patch is focusing effectively vertically but there is lateral deviation of images ie seeing double/split images laterally - rangefinder prism problem? Cannot get over how small the rangefinder viewing eyepiece is - the Leica LTM eyepieces are giants when compared to the Alpa. I see from the Alpa 7 manual that you could get a rangefinder eyepiece attachment (Oculur - can get optician to insert glass for you optical formula) to screw over the existing one. Anyone know of the existence/availability of these? Also for the larger prism eyepiece is there a rubber cover that can be placed over the metal rim (looks like it could scratch your glasses). Was there anything made for that (rubber eyepiece cup etc) or do you have to improvise her.
Luckily there is someone here in Brisbane that can work on Alpas (he has a collection AFAIK). I'll shoot a roll of trial film then get the camera CLA'd.
I see that we have a Tasmanian Devil on board - Brett, you wouldn't still have that Alpa book so you could more accurately determine DOB (date of birth) of my camera. Many thanks for your informative data on these amazingly bizarre cameras.
I'm also considering using the lens with my LTM Leicas (IIIa, IIIf & IIIg). Kipon make an Alpa Kern to LTM adapter - anyone tried this - wondering how accurate is re effective focusing. That with an LTM to M adapter will enable use on my M's (M3, MP & M240) hopefully.
I have so many more questions to ask.
Can upload more images if anyone is interested
Cheers, Stephen (romualdo)

Dear Stephen,
According to the records reproduced in Thewes's book, your Alnea 7 was manufactured during 1955.
Cheers,
Brett
Many thanks Brett, Do you have any idea how many 7's were produced?
A comment I have seen online somewhere was that only 20 to 22,000 Alpas were/have been made in toto - can you confirm that?
The person I mentioned previously in Brisbane who is an Alpa afficonado (he told me he had a collection of them) has a shop in the northern outer suburbs of Brisbane (Margate) - see website below (Alan Robertson)

Hi Stephen,
The 7 had a higher specification than Eg the 4, 5 and 6, because the 7 and its derivatives the 7s, 8, 7b and 8b, were the only Alnea-based models to incorporate the additional coupled rangefinder, (with or without a split-image rangefinder reflex focusing screen, depending on the exact model). Perhaps surprisingly, then, the 7 is still one of the more numerous production ALPA models with 3884 examples of the base 7 version recorded.
As to the overall number of 35mm ALPAs made by Pignons over the years, I am not sure if anyone has ever verified an accurate total, because as I understand it there are a few inconsistencies in the factory records. Around 40,000 is the number which seems to be most frequently suggested, though.
Cheers,
Brett
Not particularly being an adherent to the cult of Leica I tend not to quantify anything photographic by comparison with their products, so I couldn't say. But by ALPA standards, where several types have a total production measured in a few dozen (or even single figures, in some cases), a production of nearly 4000 is still a significant number. It's of no real consequence anyway to my way of thinking. Either you like the camera, the images it makes and its features, or you don't. If it works for you, that's the main thing. Personally, the Alnea 7 was the particular model I most wanted because the ALPA lenses are very good, and the idea of a single lens reflex that additionally incorporates a coupled rangefinder is fascinating, technically, to me. A 7s or 8 would have been even better, with their additional split RF reflex screen, but prohibitive cost-wise (the 7s is truly rare) however a 7 is good enough for me. I have an Alnea 5 and 11si also, so I count myself very fortunate indeed.Brett, 3884 is still very low numbers when compared to the production output for many of the Leica models.
I ended up putting an O ring round the larger eyepiece - affords some protection but not totally (scratching glasses) - really need something that covers the rim - mdid a search online last night & couldn't find anything that could work.
Spent a bit more time looking at the various range finder settings - for some reason the 90 setting gives me the clearest image (even operable without glasses). The lateral splitting/deviation of the image is annoying but the vertical focusing appears to coincide with the prism (ground glass screen) at distance but close up they are totally out. BTW what is the closest focusing distance of the K-S 50mm f1.8 lens (non macro) - the lens shows 3 1/4 feet in black then the next reading in red is 1/15, continuing in red to 1/12, 1/10 & finally 1/9 - having trouble interpreting these readings.
Cheers

Thewes's book states a minimum focus distance of 53.5 centimetres or 1 3/4 feet for the 50mm Switar, and 28 centimetres or 11 inches for the 50mm Macro-Switar.
I can probably offer some informed comments about rangefinder adjustment of your 7, and perhaps some images of the rangefinder optics, however I am travelling again for the next few days, and won't be able to follow it up until some time next week, sorry. But the only way to really get to the bottom of what your camera is doing, focus-wise, is to take it back to square one. The lens focus adjustment of a camera is always set so that at the infinity stop, a sharp image of a subject at infinity is recorded at the film plane. The means by which a user adjusts said focus (reflex focus screen, coupled rangefinder, even TLR viewing lens, in the case of a TLR) is always calibrated so that it accurately matches the film plane, never vice-versa.
Hence, you can't draw any conclusions at all until you have established what the film plane focus accuracy is like. If the primary focus (the film plane) looks good, then, and only then, may you really establish what the accuracy of the reflex focusomg screen (and the rangefinder focus in the case of the 7, being a hybrid focus design), is. Once you're satisfied that the primary focus is, indeed, good, you may consider adjusting the user focus viewing system to agree with the film plane.
Let me put it another way, in the interest of an abundance of clarity: the film plane focus is your master reference. Only when this is verified good should you consider dialling in the reflex or rangefinder to match it. In the case of a 7 or 8 ALPA, you get the bonus technical challenge of dialling in both the reflex focus screen sharpness and that of the coupled rangefinder, until all three individual focus references agree. So, check the film plane first. Then and only then, can calibration of the screen and rangefinder be contemplated.
Cheers,
Brett
