‘Contemporary’ versus ‘Art’ and ‘Sport’
Sigma’s ‘Global Vision’ line of lenses accommodates three sub-brands: ‘Art’, which Sigma reserves for its best-performing and costliest optics, ‘Contemporary’, which describes the firm’s fanatic lenses, with an emphasis on compactness and distinctive or uncommon focal size ranges, and ‘Sport’, which is the model that Sigma makes use of for its lengthy telephoto primes and telezooms.

Weighing in at solely 450g (~1lb) and measuring simply 100.6mm (~4 in) it is an ideal companion to smaller full-frame ILCs like the Panasonic Lumix DC-S5, however would not really feel unbalanced even on a bigger physique like the S1R pictured above.

The solely bodily controls on the lens barrel are a spotlight ring (of knurled plastic) a rubberized zoom ring and an AF/MF toggle change.
