The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Sony FE 50mm F2.5 G 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. Sigma 60mm F2.8 DN is the longer of the two lenses at 56mm. The Sony FE 50mm F2.5 G with a length of 45mm, is 11mm shorter. On the other hand, the Sony FE 50mm F2.5 G has a larger diameter of 68mm 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. Sony FE 50mm F2.5 G weighs 174g, which means it is 16g (8%) lighter than the Sigma 60mm F2.8 DN which has a weight of 190g.
