Description

Industar-50-2 is a compact, manual focus, 50mm prime lens with an aperture range from f/3.5 to f/16. It was manufactured in the Soviet Union and is known for its simplicity, affordability, and portability. The lens design is based on the Carl Zeiss Tessar optical scheme, featuring 4 elements in 3 groups. Specifications: Mount Types: M42 screw mount Aperture: f/3.5 to f/16, with 7 aperture blades Minimum Focusing Distance: 0.65 meters Filter Thread Size: 35.5mm Weight: Approximately 75 grams Focus Ring Rotation: 315° Optical Performance: The lens is known for good center sharpness but has softer corners, especially on full-frame cameras. On APS-C cameras, the crop factor improves edge sharpness by effectively reducing the field of view. The lens is prone to flare and vignetting, particularly when used wide open at f/3.5. These issues are somewhat mitigated when stopped down to smaller apertures. The bokeh produced by this lens is often described as harsh. Usage Considerations: The aperture ring is positioned at the front of the lens and is click-less, making it easy to change settings accidentally. This can be a downside for photographers who need precise control over aperture settings. The lens is very lightweight and compact, making it an excellent travel companion. Ergonomically, it may be challenging for users with larger hands due to its small size. Pros and Cons: Pros: Very affordable and easily adaptable to modern cameras. Compact and lightweight, suitable for travel. Good optical performance in terms of center sharpness and contrast. Cons: Soft edges and corners on full-frame cameras. Prone to flare and vignetting. Ergonomics can be challenging due to the small size and front-positioned aperture ring.
