DxO’s Optics Modules offer unparalleled corrections, including unique lens softness improvements and distortion corrections that maximize field of view. DxO’s software now corrects more than 80,000 lens and camera combinations.

Paris (France): DxO, the company that has pioneered calibration-based optical corrections for 20 years, today announces its latest batch of Optics Modules. The release of 1,693 DxO Optics Modules includes support for the Canon EOS R6 Mark II, the Fujifilm X-T5, the Sony A7R V, five lenses from Sigma, and more.

For quality-conscious photographers, DxO Optics Modules are a wealth of individually tailored, laboratory-grade corrections, which present the most accurate and powerful route to improving image quality on the market. Superior to other optical correction software, DxO’s adjustments vastly improve results, whether they are applied to entry-level lenses or professional-grade glass.

Essentially, the performance of any lens can be boosted by processing RAW files with DxO software: PhotoLab, PureRAW, FilmPack, and ViewPoint.

A unique approach to defeating lens softness

All correction software offers digital sharpening to combat lens softness, but DxO’s approach is unique and superior, taking into account the varying levels of sharpness across a lens’s entire field of view. Rather than applying general sharpening across the entire image (as with lesser software), DxO Optics Modules target sharpening as required, such as when a lens gets progressively softer towards its edges.

As seen with the Sigma 65mm F2 DG DN, the boost in image quality by DxO Optics Modules makes it perform better in terms of sharpness and distortion (while also eliminating vignetting and aberrations). As illustrated below, nowhere is this clearer than in combating lens softness. 


  • The uncorrected lens displays a significant difference in sharpness between the center of the frame and the corners.


  • Typically, photo editing software uses a generic profile to make a global correction across the entire image based on the sharpening required at the center.


  • Edge of frame sharpening from Adobe Lightroom® (left) and DxO Optics Modules (right). Unlike Adobe Lightroom, DxO Optics Modules are able to progressively increase corrections away from the frame’s center, allowing for a sharper overall image.

Sophisticated distortion corrections deliver greater image area

DxO’s Optics Modules frequently deliver a greater image area thanks to more refined assessments when correcting distortions. When needed, DxO Optics Modules give photographers the option to gain extra image area when compared with the crop applied as the result of Lightroom’s corrections.

Intelligent control of chromatic aberration

In addition, DxO’s Optics Modules remove chromatic aberrations — both longitudinal, and lateral. Chromatic aberrations vary depending on the focal length and distance, and DxO’s algorithms take these into account in order to perform more accurate corrections. Colored outlines are removed without degrading the image’s color or detail.

Vignetting accurately removed

Finally, vignetting is resolved, correcting the darker edges of the frame that can occur in certain lenses and at specific focal lengths.

The most exacting science, the highest quality

Each DxO Optics Module is created using individual camera and lens combinations. This means that any minor differences in the performance of a sensor can be measured across all the examples of it in a manufacturer’s lens mount range. 

For instance, with the new Optics Modules for the Sigma 150-600mm F5-6.3 DG DN OS S, measurements were not made using just a single full-frame Alpha camera, but with almost every Sony camera on the market.
