Sadly, for the NIKKOREX 35, many problems arose upon its release. Nippon Kogaku K. K. was not experienced in mass-production of relatively low cost cameras. As well, this was the first time that the company outsourced assembly operations for one of its cameras (some say the work was done by Mamiya, but I have not been able to confirm that) and there was much confusion caused by the difference of company cultures.
Subcontractors had great diffculty in doing things which were easily accomplished in Nippon Kogaku. Engineers and technicians were frequently sent to teach and train them, but improvement was slow. It did not help that the Citizen lens shutter was not a great match for the camera's other mechanisms, and this also caused problems.
----The NIKKOREX 35-II (35/2), released in 1962, was significantly improved compared to the original Nikkorex 35.
On the surface, there wasn't much change in specifications, other than a switch of the shutter unit from a Citizen MVL to a Seikosha (now Seiko Precision Inc.) SVL. Even today, changing shutter units means almost total change in the camera body's mechanisms;, and so it was with this NIKKOREX 35II (35/2).
The drawings below compare two internal mechanisms. The NIKKOREX 35's complicated mechanical structure includes several levers, rack gears, cams and shafts located at the bottom of the body. However, most of their function was integrated into a single large lever in the NIKKOREX 35II(35/2), thus simplifying the camera, making it far more reliable.
Despite the fact that the Nikkorex 35/2 was now an excellent, robust & reliable camera, the original Nikorex 35 had acquired a reputation for poor reliablity that would simply not go away.
In order to distinguish the new 35II (35/2) from its predecessor, its creators gave it a new external design. The top cover, the film advance lever and some other components were re-designed. The octagonal body shape of the NIKKOREX 35 was changed to the square one with rounded corners.In spite of such efforts, the NIKKOREX 35II(35/2) did not sell well. The reputation of the original model proved impossible to overcome.
Still, the 35/2 was an excellent camera, with fine Nikkor lens and a very good shutter. The Nikkorex 35/2 still did not have an instant return mirror, so you had to wind the film to lower the mirror, so that you could see through the finder. Even for it's day, it did not have a huge array of features. One that I did like was the small window in the top of the "hump", where you could see the "match needle" metering. In this way, you could set the exposure with the camera at waist level, and only raise the camera to your eye, to shoot. Great for candid shots!
I took my 35/2 to Europe for 7 weeks, during the summer of 1964 and I still have many fine slides from that trip. When I dropped the camera in Germany, on to a concrete dock, the eyepiece popped out and fell into the Rhine river. However, I was still able to use the camera ... though it was inconvenient.
When I held the camera to my eye, nothing would be in focus, without the missing eyepiece. So, I'd hold the Nikkorex at arm's length and, peering through the small hole in the back, was able to focus on the ground glass screen. Then, I'd put the camera to my eye and, knowing that the green blob was a tree, the brown blob a building and the brightly coloured blobs were my friends, I'd compose and press the shutter.
Despite this problem and it's horrible crash onto concrete, the camera continued to perform beautifully. Eventually, like many cameras I've owned, I took it apart to see what made it "tick".
Recently, I purchased another Nikkorex 35/2, at a flea market, just to have as a souvenir of the very first camera I owned. (That's it, at the top, right, of this page.)
If you found this, or any of my reviews, helpful, please consider supporting this effort by purchasing one of my e-books for just US$6.99. The "Brief HIstory of Photography" is, by far, the most popular and should be required reading for any photographer. Thank you.
