The long lens barrel provides plenty of room for large focus and zoom rings and its internal focusing and zoom systems ensure that the lens remains the same length during operation.
Sigma 50 100mm 1 8 on full frame.
Autofocus is powered by sigma s hsm motor for quick and quiet performance and the sigma 50 100mm f 1 8 a offers full time manual focus override.
It s a fast telezoom designed specifically for canon nikon and sigma aps c bodies providing 75 150mm equivalent range 80 160mm on canon bodies.
Taking photos at 100mm f 1 8 produces incredible bokeh and a thin depth of field like fast glass on a full frame camera.
Designed as an ideal complement to the 18 35mm f 1 8 this lens is designed to replace three primes with 35mm equivalents of 85mm 100mm and 135mm without sacrificing a fast aperture.
The sigma 50 100mm f1 8 is a bit of a rarity.
The sigma 50 100mm f1 8 dc hsm art 1 099 is a premium telezoom lens aimed at photographers working with aps c slrs.
It s designed around the same principle as the standard 18 35mm f1 8 dc hsm.
Like the 18 35 the 50 100 is a dc lens compatible only with aps c format sensor cameras.
I highly recommend this lens as well as the 18 35mm 1 8 by sigma.
Canon and sigma mount versions should also work on sony e mount cameras with sigma s new mc 11 adapter.
The 50 100mm f 1 8 dc hsm art for nikon f canon ef and sigma sa aps c cameras is one of the oddest with a fast constant aperture and a short telephoto to medium telephoto range equivalent to 75 150mm.
