Our Image Engineering MTF tests were carried out with the lens mounted to Canon’s 50-million-pixel DSLR, the EOS 5DS R.

Again, the characteristics of the optical design focus on this, so to speak, while the aperture diaphragm is based on 11 curved blades compared with the 8 blades of Sigma’s previous 50mm Art lens.
