CFE 4/40 IF specifications

The Hasselblad CFE 4/40 IF is a noteworthy addition to the prestigious lineup of medium format lenses, designed specifically for Hasselblad's V System cameras. This lens combines advanced optical design with user-friendly features, making it a favored choice among professional photographers and enthusiasts alike.

One of the standout characteristics of the CFE 4/40 IF is its impressive focal length of 40mm, which provides a versatile wide-angle perspective, ideal for landscape photography, architecture, and interior shots. The lens offers a moderate perspective distortion, making it easier to capture natural-looking images without excessive bending of lines or shapes. Furthermore, the lens's aperture range from f/4 to f/32 allows for both shallow depth-of-field effects and excellent sharpness across a range of lighting conditions.

The lens features a leaf shutter design that allows for flash synchronization at all shutter speeds, a significant advantage for photographers who often work with speedlights or strobes. This feature enables the user to take advantage of daylight fill flash without having to worry about high-speed sync settings. The quick and quiet operation of the leaf shutter is also appreciated in situations where subtlety is required.

Another key technology incorporated into the CFE 4/40 IF is its integrated floating element system. This design ensures that the lens maintains exceptional optical performance across all focusing distances. Whether shooting near or far, photographers can expect sharpness and clarity. The lens is also coated with advanced multi-layer anti-reflective coatings, reducing flare and improving contrast in challenging lighting conditions.

Build quality is another defining feature of the CFE 4/40 IF. Constructed with precision engineering, the lens has a robust and durable design while remaining relatively lightweight, making it convenient for extended shooting sessions. The focus ring is smooth and well-damped, allowing for precise adjustments, whether for general photography or close-up work.

In conclusion, the Hasselblad CFE 4/40 IF encapsulates a harmonious balance of performance, craftsmanship, and innovative technology. With its wide-angle capabilities, integrated shutter system, and exceptional optical characteristics, this lens is an outstanding tool for capturing breathtaking images while ensuring ease of use for photographers of varying levels of expertise. As part of Hasselblad’s rich heritage, this lens not only meets the demands of contemporary photography but also reflects the brand's commitment to quality and excellence.
