Praktica BC3

History

The Praktica B mount was introduced with the B200 in 1979, replacing the M42 screw thread that had defined the Praktica system since the postwar years. M42 had served Praktica well - it was also used by Pentax, Fujica, Mamiya, and many others, creating a large shared lens ecosystem - but the thread mount could not support the electronic aperture coupling that AE bodies required. The B bayonet addressed this by providing electrical contacts within the mount.

The BC series represented the consumer mid-range of the B-mount lineup: BC1 (~1984), BC2 (1986), BC3 (~1989). Each step refined ergonomics and finish without fundamentally altering the mechanism. The BC3 is distinguished from the BC2 by minor improvements to the control layout and reportedly to the viewfinder.

Production ended definitively around 1990-91 as the East German state manufacturing apparatus was dissolved following reunification. VEB Pentacon was liquidated; the Praktica brand was subsequently acquired and revived under western management, producing cameras under the Praktica name but without continuity of the Dresden engineering tradition.

The BC3 is therefore among the last cameras manufactured in the line of East German SLR production that traces directly back to the KW Praktiflex of 1938 and the postwar Contax S - the first pentaprism SLR - produced by the same Dresden works.

Why It Matters

The Praktica BC3's significance is primarily historical: it is a terminal product of the East German camera industry, made in the final months before reunification ended state manufacturing. The Dresden camera tradition was one of the most technically important in the world from the 1930s through the 1960s - it produced the first pentaprism SLR, established the M42 thread mount as an industry standard, and manufactured cameras of genuine quality under difficult postwar conditions.

By 1989, that tradition was exhausted commercially. The BC3 cannot compete with a contemporary Canon EOS 650 or Nikon F-801 on metering sophistication, autofocus, or build quality. What it offers is continuity with that lineage, at very low cost on the used market.

For collectors, the BC3 is a low-commitment way to hold a piece of the final Dresden era. The Pentacon 50mm f/1.8 that was commonly bundled with BC-series bodies is a genuinely useful standard lens with character, and the camera will work adequately for manual-focus 35mm shooting as long as the electronics are functioning.

Lenses & Accessories

The Praktica B bayonet provides electronic aperture coupling; lenses must be native B-mount for AE operation. M42 lenses can be adapted with a simple ring, with stop-down metering only.

Key native B-mount lenses:

• Pentacon 50mm f/1.8 - standard kit lens, most common B-mount glass; multi-coated, solid performer for the price
• Pentacon 135mm f/2.8 - popular telephoto, widely available, usable for portrait work
• Pentacon 29mm f/2.8 - wide angle; less commonly encountered
• Pentacon 80-200mm f/4.5 zoom - consumer zoom of the era; variable quality
• Sigma, Tamron B-mount variants - some third-party manufacturers produced B-mount lenses; availability varies significantly by market
• M42 adapter - allows use of any M42 lens; stop-down metering, no AE

Sample Photographers / Notable Use

• Used by East German amateur and semi-professional photographers in the late 1980s as the current-generation Praktica mid-range SLR.
• Collected by photographers interested in the DDR manufacturing legacy and East German camera history.
• Occasionally adopted by contemporary photographers working with the B-mount system who need a second or student body.
