Schneider-Kreuznach 150mm f/4.5 Xenar Linhof Synchro-Compur BT (39MT) 4x5 Lens Review

The Schneider-Kreuznach 150mm f/4.5 Xenar is a classic large format lens designed for 4x5 cameras, mounted in a Linhof Synchro-Compur shutter with a 39MT thread. Schneider's Xenar line has long been respected for delivering sharp, dependable optics at a more accessible price point than their premium Symmar or Apo-Symmar designs. The 150mm focal length serves as a standard lens for 4x5 work, roughly equivalent to a 50mm lens in 35mm terms, making it a versatile choice for landscape, architecture, and studio photography.

This particular unit is sold as used in bargain condition from KEH at $166, which positions it as an entry point for photographers looking to explore or expand their large format toolkit without committing to premium glass. The Synchro-Compur shutter offers reliable mechanical performance and flash sync capability. At f/4.5, it's a full stop slower than the more common f/3.5 versions, which may limit use in lower light but contributes to a more compact, affordable design. For shooters comfortable with the slower maximum aperture and the compromises of bargain-grade cosmetics or wear, this lens offers a practical path into large format imaging.
