Sigma 10-18mm F2.8 DC DN | Contemporary Lens for Canon APS-C RF System
The Sigma 10-18mm F2.8 DC DN | Contemporary lens is evaluated in this article for the Canon APS-C RF system. Despite its dependence on optical corrections, this lens is compact and has a fast fixed aperture for ultra-wide-angle shots. This is something we have never seen from Canon for their crop sensor cameras.
Although there are no specific reviews for the Canon RF system and this lens, we can refer to reviews for Fuji and Sony for comparison. The optical formula of this lens is the same, with adjustments made for autofocus algorithms and communication with the RF camera body.
According to the review from OpticalLimits, the Sigma 10-18mm F2.8 DC DN Contemporary lens is compact and lightweight, while delivering very good image quality. The resolution in the center of the image is not the best, but the quality at the edges is still very good in all important settings. The angle of view is also good at 10mm but slightly softens at longer focal lengths, although the results are still stable at a good level even at F2.8 aperture.
According to CameraLabs, the Sigma 10-18mm F2.8 DC DN lens is a very welcome addition to the APS-C system, being lightweight and affordable, while delivering impressive results for landscapes, interiors, and video shooting. However, one should not expect too much from the wide aperture. The image is sharp in the center but slightly softens when approaching the corners, especially in wider focal ranges.
Compared to Canon, Sigma performs better in the wide-angle range. However, when comparing at F5.6 aperture, Sigma outperforms the Canon 10-18mm lens.
In conclusion, the article recommends purchasing the Sigma 10-18mm F2.8 DC DN lens due to its compact size, large aperture, and good performance in the wide-angle range. Although it lacks image stabilization function, it provides better light and performance in the wide-angle range. This is a great lens combination when paired with the Sigma 18-55mm F2.8 DC DN for Canon RF APS-C cameras.
