50mm vs 35mm Lens Specs
Sensor Format
Product A, the Samyang AF 50mm F1.4 II, is explicitly designed for full frame sensors. This ensures the lens covers the entire image circle of Sony full frame mirrorless cameras without vignetting or cropping. Product B, the Samyang 35mm F1.4, lists its attributes as compatible with the Sony E-Mount but does not explicitly state a full frame designation in the provided data. You should verify if Product B is optimized for full frame or if it is an APS-C specific lens, as this drastically changes the field of view and image quality on your camera body. Using an APS-C lens on a full frame body results in significant cropping.
Focal Length
The Samyang AF 50mm F1.4 II offers a 50mm focal length, which is a classic standard perspective. It mimics the natural field of view of the human eye, making it versatile for portraits, street photography, and general documentation. The Samyang 35mm F1.4 provides a wider 35mm perspective. This wider angle is better for environmental portraits, indoor spaces, and landscape photography where you need to include more of the surroundings. The choice depends on your preferred composition style. A 50mm lens isolates subjects more effectively, while a 35mm lens includes more context.
Build Quality
Product B, the Samyang 35mm F1.4, features a durable design with robust sealing. This protection against dust, moisture, and light rain makes it suitable for outdoor, travel, and street photography in challenging weather conditions. Product A, the Samyang AF 50mm F1.4 II, does not mention any weather sealing in its specifications. It is described as compact and lightweight, weighing only 492 grams. While it is the smallest and lightest 50mm lens for Sony full frame, it lacks the explicit environmental protection found in Product B. If you shoot in rain or dusty environments, Product B offers better physical resilience.
Autofocus System
Product B utilizes a Linear STM motor for autofocus. This system is engineered for smooth, precise, and silent operation, which is ideal for both stills and video shooting. Silent operation prevents audio interference during video recording. Product A, the Samyang AF 50mm F1.4 II, is listed as having autofocus but does not specify the motor type in the provided data. It does mention a custom switch for aperture control via the focus ring and a focus hold button. However, without knowing the motor technology, you cannot be certain of its speed or silence compared to the Linear STM in Product B. Product B has a clear advantage in specified AF performance.
Connectivity
Product B, the Samyang 35mm F1.4, includes an integrated USB port. This allows you to perform easy firmware updates and customize settings directly on the lens. Keeping the lens firmware updated ensures compatibility with future Sony camera innovations and can improve autofocus performance or fix bugs. Product A, the Samyang AF 50mm F1.4 II, does not mention a USB port or any connectivity options in its specifications. It relies on traditional lens controls and does not offer a way to update its internal software. For users who want to maintain their gear with the latest features, Product B provides a significant functional advantage.
Optical Construction
Product A, the Samyang AF 50mm F1.4 II, uses 11 elements in 8 groups, including 6 special lenses. These include two aspherical elements, three high-refractive elements, and one extra-low dispersion element. All elements feature Samyang Ultra Multi Coating to reduce flare and ghosting. Product B, the Samyang 35mm F1.4, uses 12 elements in 10 groups, including aspherical and high-refractive lenses. It aims for edge-to-edge sharpness and minimal chromatic aberration. Both lenses use high-quality glass and special coatings. Product B has slightly more elements and groups, which may help control aberrations in a wider angle lens, but both are engineered for high optical precision.
Weight and Size
Product A, the Samyang AF 50mm F1.4 II, weighs 14.8 ounces and measures 3.5 inches in length. It is marketed as the smallest and lightest 50mm lens for Sony full frame mirrorless cameras. This compactness makes it easy to carry for all-day shooting. Product B, the Samyang 35mm F1.4, measures 3.9 inches in length but does not list a weight in the provided data. Its wider focal length and additional sealing may contribute to a different physical profile. If your priority is minimal weight and compactness for travel, Product A is the lighter and more portable option. You should check Product B's weight separately if it is not listed.
