ephotozine reviewed the Sigma 50-100mm f/1.8 DC HSM Art lens, another crazy and hot lens for APS-C DSLRs in Sigma’s new “Art” line-up.
In the conclusion they write:
The Sigma 50-100mm f/1.8 DC Art lens is a fine example of the lens maker’s art. The zoom range is limited, it’s heavy and it could perhaps focus a little closer, but apart from that it would be difficult to find fault with any aspect of its performance.
The sharpness reaches outstanding levels across the range of focal lengths, distortion is low, CA well controlled and the overall appearance of the images is very appealing. The clincher is, of course, that f/1.8 aperture, which opens up a realm of possibilities in low light and for control of depth of field. A lovely lens that’s a pleasure to use.
If I am not wrong, the Sigma 50-100mm f/1.8 DC HSM is one of two unique lenses for APS-C having a constant f/1.8 over the zoom range, the other lens being the Sigma 18-35mm f/1.8 DC HSM.
