Instead, because the lenses are often softer at the frame’s corners than in its center, the profiles gradually apply adjustments with higher strengths to those areas.
The fact that DxO Labs does not apply global adjustments throughout the full frame is one of the more distinctive characteristics of these Optics Modules.
DxO Labs singles out one instance when measurements were taken for “the new Optics Modules for the Sigma 150-600mm F5-6.3 DG DN OS S” using “nearly every Sony camera on the market, rather than just one full-frame Alpha camera.” DxO Labs asserts that by creating profiles for various camera and lens combinations, it is better able to make any necessary minor adjustments when a specific lens is used on one camera as opposed to another.
