The TTArtisan 100mm F2.8 Macro provides up to 2x macro coverage for full-frame sensor, it has a manual focus design to suits its macro capabilities, which permit working with subjects as close as 2:1 with a minimum focusing distance of 25cm (9.8)" .
The tilt-shift lens affords +/- 6mm of shift and +/- 8° of tilt, and both types of movements can be applied independently. The tilt-locking mechanism ensures the lens stays in place while shooting. Additionally, the tilt and shift functions can be rotated +/- 90° for applying the movements in distinct directions.
This lens has an optical design of 14 Elements in 10 Groups that with 6 high refractive index glass elements help to control distortion and spherical aberrations for improved sharpness and accurate rendering.
The f/2.8 aperture is designed to suit work in low lighting conditions, 12-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
