The new BLACKWING7 lenses are Large Format T1.9 tuneable lenses based on designs from the early 20th century. The optical design allows for the flexibility to provide varying degrees of spherical aberration, halation, and flare. This offers varying degrees of smoothness to the in-focus image area, different amounts of focus roll off in the out-of-focus areas, and unique flare characteristics. T-tuned BLACKWING7 lenses have a profile which further softens the roll-off to the edge of the frame, and provides increased edge detail halation. T lenses are designed to capture a slightly softer, artistic image, with a higher degree of light reactivity and flaring characteristics are harder and more prominent than with the S-tuned version.
