Sigma FT-1201 Conversion Lens
The Sigma FT-1201 Conversion Lens is exclusively designed for the Sigma DP3 Quattro.
When it is attached to the front of the lens, it magnifies the focal length of the lens by 1.2 times (60mm / equivalent to 90mm on a 35mm format), and does not change the f/2.8 aperture value. It consists of 4 ultra-high quality lens elements in 3 groups, and maintains excellent rendering performance while offering a different focal length and therefore more shooting possibilities.
Lens Construction: 4 elements in 3 groups Focal length: 1.2x that of a master lens
Dimensions (Diameter × Length): ø 70mm×54.9mm/2.8in. x 2.2in.
By attaching the Conversion Lens to DP3 Quattro, it can change the minimum focusing distance and the maximum magnification ratio as follows; (22.6cm/1:3 → 29.4cm/1:3.6)
