Pre-Owned - DeJur Auto 2X Teleconverter for Minolta MD

Pre-Owned - Sakar Auto 2x Tele Converter for Minolta MD Mount

The DeJur Auto 2X Teleconverter for Minolta MD is a vintage optical accessory that doubles the focal length of a Minolta manual-focus SLR lens while reducing light by two stops (a loss of 2 EV).

Key Specifications & Features

• Compatibility: Designed for Minolta manual-focus SLR camera bodies and MD/MC mount lenses.

• Magnification: 2.0x focal length multiplier (e.g., turns a 50mm lens into a 100mm lens).

• Focus & Iris: Retains mechanical linkage for auto-aperture (stop-down metering/operation), though focusing remains manual.

• Build: Metal-alloy construction, typically manufactured in Japan during the vintage film era.

• Market Price: Generally sells on secondary platforms like eBay for roughly $10 to $25 USD used, depending on condition and whether caps or a case are included.

Performance Considerations

• Light Loss: A 2x teleconverter costs you 2 stops of light. For example, an f/1.4 lens becomes an effective f/2.8 lens, and an f/4 lens becomes f/8.

• Image Quality: Third-party budget teleconverters from brands like DeJur can introduce softness, lower contrast, and chromatic aberration (color fringing), especially when paired with already-zoomed or slower prime lenses.
