However, the price difference corresponds to the different functionalities and target audiences of each lens, with the Canon lens providing a longer focal range suited for different types of photography.

Target Audience

The Canon RF100-400mm F5.6-8 is USM targets wildlife and sports photographers who require the ability to zoom in on distant subjects. Its features are tailored for users who prioritize high image quality and stabilization, making it suitable for various challenging shooting conditions. On the other hand, the VILTROX AF 9mm F2.8 is aimed at landscape photographers, vloggers, and those who enjoy wide-angle shots. Its compact design and low-light capabilities cater to a different segment of the market, allowing for creative flexibility in diverse shooting environments.

Performance in Different Conditions

In terms of performance, the Canon RF100-400mm boasts an Optical Image Stabilizer that provides up to 5.5 stops of shake correction, which is essential for handheld shooting, especially at longer focal lengths. When paired with EOS R series cameras with In-Body Image Stabilization, it can achieve up to 6 stops of correction. This makes it an excellent choice for dynamic environments like sports events. Conversely, the VILTROX AF 9mm F2.8 shines in low-light scenarios due to its bright F2.8 aperture, making it perfect for night photography and astrophotography, where capturing details in low light is crucial.

Autofocus and Usability

The Canon RF100-400mm features Canon’s Nano USM technology for fast and quiet autofocus, which is ideal for capturing fleeting moments in wildlife photography without disturbing the subject.

Image Quality

Both lenses deliver impressive image quality, but their strengths differ. The Canon RF100-400mm is designed with a single Ultra Low Dispersion lens element, effectively reducing chromatic aberration across its zoom range, thus producing crisp and colorful images. This makes it a go-to for capturing detail in wildlife and sports. Meanwhile, the VILTROX AF 9mm F2.8 offers a unique perspective with its ultra-wide angle, perfect for expansive landscapes and creative compositions. While it may not have the same level of zoom capabilities, it compensates with its ability to create dramatic images through wide-angle distortion.

Which should you buy?

Choosing between the Canon RF100-400mm F5.6-8 is USM and the VILTROX AF 9mm F2.8 APS-C Lens ultimately comes down to your specific photography needs and budget. If you are a wildlife or sports photographer seeking versatility and superior image quality at longer distances, the Canon lens is a worthy investment despite its higher price. However, if you are focused on landscapes, vlogging, or require a lightweight option for creative photography, the VILTROX offers excellent performance at a significantly lower price. Consider your photography style and the types of scenes you wish to capture when making your decision.
