The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Samyang AF 50mm F1.4 FE and the Sigma 60mm F2.8 DN for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Samyang AF 50mm F1.4 FE is the longer of the two lenses at 98mm. The Sigma 60mm F2.8 DN with a length of 56mm, is 42mm shorter. Besides being longer, the Samyang AF 50mm F1.4 FE also has a larger diameter of 74mm compared to the Sigma 60mm F2.8 DN's 61mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Sigma 60mm F2.8 DN weighs 190g, 67% (395g) lighter than the Samyang AF 50mm F1.4 FE's weight of 585g.
