Overview of the Viltrox 25mm F1.7 E

The Viltrox 25mm F1.7 E is a prime lens tailored for Sony E mount cameras, priced at $176.00. It features a bright f/1.7 maximum aperture, which excels in low-light conditions and provides excellent depth of field control. Weighing only 170 grams, this lens is lightweight and portable, making it suitable for everyday use and travel. The lens utilizes an STM stepper motor for quiet autofocus, ensuring that it doesn’t disrupt photo or video sessions. This lens is ideal for those looking for a reliable and efficient option for both photography and videography.

Image Quality Comparison

When it comes to image quality, the Canon RF100-400mm F5.6-8 is USM stands out with its advanced optical design that includes a single Ultra Low Dispersion lens element, effectively minimizing chromatic aberration. This results in crisp and colorful images across the entire zoom range. In comparison, the Viltrox 25mm F1.7 E offers a bright aperture that enhances low-light performance but lacks the long-range versatility of the Canon lens. Therefore, while the Viltrox excels in scenarios requiring a fast aperture, the Canon lens provides superior overall image quality for varied shooting conditions.

Autofocus Performance

The Canon RF100-400mm F5.6-8 is USM features a high-speed Nano USM autofocus system, which is particularly beneficial for capturing fast-moving subjects in wildlife and sports photography. This technology ensures smooth and quiet operation, making it a strong choice for dynamic environments. On the other hand, the Viltrox 25mm F1.7 E uses an STM stepper motor that also provides a quiet autofocus experience, making it suitable for video recording and discreet photography. Both lenses offer effective autofocus, but the Canon lens may have the edge in speed and versatility due to its advanced technology.

Portability and Design

In terms of portability, the Viltrox 25mm F1.7 E is significantly lighter at just 170 grams, making it an ideal companion for travel and everyday use. The compact design allows for easy handling and storage. The Canon RF100-400mm F5.6-8 is USM, while still being relatively lightweight for a telephoto lens, is bulkier due to its zoom capabilities. With a length similar to the EF 70-300mm F4.5-5.6 IS II USM when extended, it is less convenient for on-the-go photographers. Therefore, for those prioritizing portability, the Viltrox lens is the more suitable option.

Price Comparison

The Canon RF100-400mm F5.6-8 is USM is priced at $699.00, while the Viltrox 25mm F1.7 E is significantly more budget-friendly at $176.00. This means the Viltrox is about 75% cheaper than the Canon lens, making it a great choice for photographers on a budget or those who need a reliable lens without breaking the bank. The substantial price difference reflects the varying capabilities between the two lenses. The Canon lens offers a broader zoom range and advanced features, while the Viltrox focuses on affordability and simplicity.

Versatility in Use

The Canon RF100-400mm F5.6-8 is USM excels in versatility with its extensive zoom range of 100-400mm, making it suitable for various types of photography, including wildlife, sports, and landscapes. Additionally, it can accept tele extenders to reach focal lengths of 560mm and 800mm, significantly enhancing its usability. In contrast, the Viltrox 25mm F1.7 E, while versatile for everyday photography and videography, is limited by its fixed focal length. Thus, for those requiring extensive shooting options, the Canon lens is the superior choice.

Which should you buy?

Choosing between the Canon RF100-400mm F5.6-8 is USM and the Viltrox 25mm F1.7 E ultimately depends on your photography needs and budget. If you are a wildlife or sports photographer looking for a high-quality telephoto lens with advanced features and broad versatility, the Canon lens is worth the investment at $699.00. However, if you are a casual photographer or videographer seeking a lightweight, affordable option for everyday use, the Viltrox lens at $176.00 offers excellent value without compromising on essential features.
