Price Comparison
The Canon RF100-400mm F5.6-8 IS USM comes at a price of $699.00, while the VILTROX 16mm f/1.8 Z Lens is priced at $580.00, making it about 17% cheaper than the Canon lens. This price difference may be significant for photographers on a budget or those looking for a wide-angle lens without breaking the bank. While both lenses offer unique capabilities, the cost may play a crucial role in decision-making, especially for hobbyists or those just starting in photography.
Lens Type and Purpose
The Canon RF100-400mm is a telephoto lens designed for capturing distant subjects, ideal for wildlife and sports photography. In contrast, the VILTROX 16mm f/1.8 is a wide-angle prime lens that excels in capturing expansive landscapes and architectural details. Each lens serves distinct purposes; the Canon lens allows photographers to zoom in on subjects from afar, while the VILTROX lens offers a broader perspective for capturing more of the scene in a single frame. This fundamental difference in lens type dictates the scenarios in which each lens shines.
Aperture and Low-Light Performance
In terms of aperture, the VILTROX 16mm f/1.8 features a super large aperture of f/1.8, which enhances its low-light performance significantly. This allows photographers to shoot in dimly lit environments without relying on a flash or increasing ISO levels. On the other hand, the Canon RF100-400mm has a maximum aperture of f/5.6 to f/8, which is less conducive to low-light shooting. Thus, for photographers who frequently work in low-light conditions or who wish to achieve a shallow depth of field, the VILTROX lens offers a clear advantage.
Autofocus System
The autofocus systems in these lenses reflect their respective designs and intended uses. The Canon RF100-400mm features high-speed, smooth, and quiet autofocus thanks to Canon’s Nano USM technology. This ensures quick focusing on moving subjects, which is crucial for wildlife or sports photography. In contrast, the VILTROX 16mm f/1.8 incorporates an STM stepping motor that provides precise autofocus and face/eye recognition capabilities. While both lenses are designed for fast and accurate focusing, the choice largely depends on whether you require the speed for distant subjects or the precision for wide-angle compositions.
Image Stabilization
Image stabilization is another critical feature where these lenses differ significantly. The Canon RF100-400mm boasts Optical Image Stabilizer technology, offering up to 5.5 stops of shake correction and even 6 stops when paired with compatible EOS R series cameras featuring In-Body Image Stabilization (IBIS). This is particularly beneficial for handheld shooting at longer focal lengths. The VILTROX 16mm, however, does not explicitly mention image stabilization features. Therefore, if stability during shooting is a priority, the Canon lens is the superior option, especially for telephoto work.
Build and Portability
The VILTROX 16mm lens is compact and lightweight, weighing only 19.9 oz (565 g), making it highly portable for street photography or travel. In comparison, while the Canon RF100-400mm is also lightweight for a telephoto lens, it is bulkier due to its zoom capabilities. For photographers who prioritize portability in their gear, especially when capturing spontaneous moments, the VILTROX lens could be the more convenient choice.
Compatibility and Versatility
The Canon RF100-400mm is designed for EOS R series cameras, while the VILTROX 16mm f/1.8 is compatible with a range of Nikon Z-Mount full-frame mirrorless cameras, including models like the Z5, Z6, and Z9. This broad compatibility means that the VILTROX lens can cater to a wider audience of Nikon users. Additionally, the VILTROX lens features a customizable button and an LCD display that shows important shooting parameters, enhancing its versatility in various shooting situations.
Which should you buy?
Deciding between the Canon RF100-400mm F5.6-8 IS USM and the VILTROX 16mm f/1.8 Z Lens ultimately depends on your photography needs. If you require a powerful telephoto lens for capturing distant subjects with optical image stabilization and fast autofocus, the Canon RF100-400mm is a strong contender, albeit at a higher price of $699.00. However, if you’re looking for an affordable, highly portable lens that excels in low-light conditions and offers a wide-angle perspective, the VILTROX 16mm f/1.8 at $580.00 is a compelling choice. Each lens caters to different styles of photography, so your decision should align with your specific requirements and preferences.
