Description — Sigma 105mm f/2.8 Macro
The Sigma EX 105mm f/2.8 Macro is a prime telephoto lens designed for full-frame DSLR systems, with a fixed focal length of 105mm and a maximum aperture of f/2.8. It is classified as a macro-type lens and fits into Sigma's EX series lineup. Mount options span Canon EF, Nikon F, Sony A, Pentax K, and Sigma SA, giving it wide cross-system appeal for DSLR photographers.
The lens supports both autofocus and manual focus, offering control flexibility across different shooting scenarios. A 58mm filter thread allows for easy integration with standard circular filters, and the lens tips the scale at 460g — a workable weight for field use.
