Some of you might have been interested in my 35 mm SLR production number assessment, which I started already in 2014. The last post of the series was a couple of months ago about the Chinese SLR production. What still is missing, is a relatively large chunk of smaller Japanese SLR producers (about 15 with numerous models), and besides Miranda I don't have single figures for any of them. I did the big four (Nikon, Canon, Pentax, and Minolta), and they make up the majority of the SLR production, but I couldn't tell, whether it is 90% or only 60%.
The other missing piece is the younger history of motorized and AF SLR cameras, which I excluded so far. As both issues are related with Japan I found a practical solution to at least give an idea about total figures: CIPA (The Japanese "Camera & Imaging Products Association") publishes statistics about numbers and other figures of sold cameras and lenses from 1951 on. They don't have a category of SLR cameras, but (from 1977 on) distiguish between Lens Shutter and Focal Plane ("FP") Shutter cameras, the latter (they say) are most exclusively SLR's. The number of Japanese leaf shutter SLR can probably be neglegted, although there were some. I was quite pleased to see that my own assessments of the big four were trend-wise very well in line with the CIPA numbers. The rest are a few simple assumptions and putting it all together, see the graph above. Here are some facts and conclusions:
- The total number of 35mm film SLR ever produced is about 212 millions. Production ceased almost completely in 2007. Neither the few which were manufactured since nor the very early models produced before 1950 would change this number.
- A significant chunk of this number, namely 53.6 millions (or 25%) belong to the last generation of highly automated, motorized and/or AF SLR. In my graph above I've assigned them to Japan, knowing that there might be production of the big four in other Asian countries. My plan is to do bottom-up assessments for these cameras as well and hope to confirm this number.
- At almost no surprise Japanese companies produced the majority of all 35mm film SLR: over 150 millions and almost 100 millions of the classical type of manual focus SLR.
- With just below 25 millions each the former Soviet Union and PR China share second place in the country ranking, although they were most active in different decades.
- Speaking of decades: The 80ies, more precisely the ten years between 1978 and 1987, was the decade with the highest SLR production. About 80 millions of the then affordable and convenient to use cameras left the factories during this period.
- 1981 was the best year of SLR production ever (9.5 million untis).
- There are only these basically four countries (if you counted the Germanies as one) with a significant production. Of course other countries had SLR production, too. However, this was either in the very early days with very low numbers (Italy: Rectaflex, Hungary: Gamma Duflex, Great Britain: Wrayflex, Switzerland: Alpa, ...?) or later when German or Japanese companies outsourced production (Leitz: Portugal; Rollei: Singapore; Minolta: Malaysia, etc.). All of them with relatively low numbers as far as I know. The only exception is outsourcing to China by Minolta and Pentax, but this has been counted for China!
- There was no production of any kind of 35 mm SLR in the USA! This is quite surprising as the US would probably rank high (if not highest) in countries, where all these SLR were sold.
This is all to my best knowledge and might bear errors, of course. If anyone has doubts or better info to offer please post a comment below! Generally, I would assume the error in the order of up to 10%. For a future post I will crunch these numbers again but focus on producers and single models rather than countries. Stay tuned...;-)
