Topcon RM300 (1978-1981)

Topcon RM300 

Características

The Topcon RM 300 is a manual focus 35mm SLR from Tōkyō Kōgaku, made by Cima Kōgaku. The body has the same features of the RE 300, but uses Pentax's K mount type lenses instead of Exakta lenses. The RM 300 is the last camera released under the Topcon brand name. The Topcon AM-1 was announced but never released by Tokyo Kogaku. Thought it was later completed and released as the Cimko LS-1. There are many other cameras based on this same body including:

• Quantaray (Delta) D2-RZ distributed in the US at Ritz Camera retail stores.
• Carena KSM1 distributed by Porst shops in Germany.
• Exakta KE 5
• Edixa CX 5
• Rony RS1, Rony was the French importer of Topcon.

Tōkyō Kōgaku tried to regain market shares by using the Pentax K-mount, and in Cima Kōgaku they had a production partner capable to produce standard lenses for different lens mounts including the K-mount.

Topcon has a long and illustrious history as a camera manufacturer; the RE Super of 1963 was the first 35mm SLR to feature TTL metering and their first 35mm SLR ever came in 1957 - two years before the Nikon F or Canonflex. By 1980 (or thereabouts) the marque had fallen a long way from its prime, and I doubt that Topcon had much to do with the actual design and manufacture of the RM300 - it gives every sign of being a generic PK mount body of a type that was very common from Cosina, Chinon, etc at the time.

Very standard specs for the time with a mechanical shutter of 1s to 1/1000, the RM300 offers a few advantages over the K1000. The vertical travel, metal bladed shutter offers a flash sync of 1/125th against the 1/60th of the K1000, and there's a self timer. Metering is center weighted averaging with traffic light LEDs rather than a needle to indicate exposure.Also as an advantage over the K1000 the RM300 accepts a motordrive.

Topcon Unirex

Topcon Unirex

Características

Topcon Unirex is made by Tokyo Kogagu Kikai, Japan or same in English, Topcon Optical Co. . Unirex is one of the first SLR:s with full aperture CdS exposure metering. Both averaged metering and spot metering are available. It looks like it should have a focal plane shutter but the truth is that this camera has a leaf shutter behind the lenses. In this case the lens is UV Topcor 1:2, F=50mm. Shutter times are B, 1 - 1/500.

Cameras which made Topcon famous as a camera manufacturer are obviously RE Super and Super Dm models. They have focal plane shutters, more extensive variety of lenses and they were aimed for more professional use as well. In United States Topcon cameras were sold under the name Beseler Topcon. I might be a misunderstanding but there were times when Topcon was an "official" camera of US Navy. Topcon cameras were often described as tanks. Something in their essence really resembles a heavy Sherman or Tiger. If you happen to see one dent on Topcon you can be almost sure that it has arised in El Alamein.
