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.
