A seriousi question...why was England or Britania never able to develop a top notch camera...they had the best radar and sonic,,,I still have this fantasy of a great digital camera made in GB...they certainly have the smarts...
They had a go...
Excellent post, Bob. Glad someone filled in that history — Britain did indeed produce several top-notch consumer cameras through the 1950s, but, as you said, they were not big commercial successes.
Just to give a super bird's eye addendum to your post, from the advent of consumer cameras (the Kodak Brownie was introduced in 1900) through the 1950s, European makers dominated the enthusiast (as opposed to snapshot) market, and there were many brands from a range of countries, including France and the UK. But Germany was by far the leader; the other European makers were all second-tier in scale.
In the 1950s, of course, the Japanese came along and devastated the European camera and consumer optical instruments industries, including Germany's. The second-tier makers, like those in the U.K. (and the U.S.) were the first to fold under this competitive pressure. The exception is medium format film cameras, where European companies competed well until the effective end of that business.
As you noted, UK (and U.S.) optical instruments manufacturers turned to the military, scientific, and industrial markets instead. There are still extremely high-technology optical firms in the UK, the U.S., and, of course, Germany (and even Canada). But they don't make a lot of consumer optics, and certainly not many cameras.
Why individual countries and regions come to dominate particular industries is always an interesting question, and I haven't read what I'm sure is copious scholarship on the issue. But it doesn't seem to me that there is any single reason; it seems particular to every industry and era.
In the case of the Japanese and optics, the country's government, in the form of its Navy primarily, specifically targeted optics as a key strategic technology and drove the development of optical technology with money and pressure on Japan's industrial leaders. The first result of this push by the government was Nikon, which was created by Mitsubishi specifically at the direction of the Japanese Navy, which also contributed money and manpower from its own research lab.
It's interesting that post-war Nikon (and other Japanese brands) made the opposite migration to that of the post-war UK and U.S. firms, with the Japanese going from making military optics to making consumer optics. An important part of the explanation for that can be found just by looking at military expenditures for those countries pre and post-war.
Already, the snapshot imaging industry has moved on from Japan to China (smartphones). And the next big opportunity for a regional shift in the enthusiast photography and enthusiast consumer optics industries is undoubtedly computational imaging. The current technological leader in that field, by a wide margin, is the U.S., but any U.S. consumer optics companies will have their stuff manufactured in China. And Chinese companies (i.e. Chinese brands) will likely win the mass market battle in the long run, no matter what.
