The Sigma lens is designed for high-performance photography, while the VILTROX offers a budget-friendly option that still caters to various photography needs.
Optical Performance
The Sigma 28-70mm F2.8 DG DN is renowned for its outstanding optical performance throughout its zoom range, which is essential for both amateur and professional photographers. This lens is known to rival the performance of the Sigma Art line, making it a strong contender for those who prioritize image quality. In contrast, the VILTROX 35mm f1.7 boasts a bright f/1.7 aperture that excels in low-light conditions and creates beautiful background blur. While both lenses deliver impressive optical results, the Sigma lens offers versatility with its zoom capabilities, whereas the VILTROX focuses on sharpness and bokeh at a fixed focal length.
Build Quality and Design
The Sigma lens is celebrated for its superb build quality, featuring a lightweight and compact body that balances performance and portability. It also incorporates advanced features like internal focusing and a focus mode switch, which enhance user experience. On the other hand, the VILTROX 35mm f1.7 is designed with thoughtful details, such as an extended lens hood for better light management and a USB-C upgrade port for firmware updates. While both lenses have their unique design strengths, the Sigma's robust build may appeal more to those who prioritize durability in professional settings.
Autofocus Capabilities
Autofocus performance is crucial for both lenses, but they differ in their approaches. The Sigma 28-70mm features a focus mode switch that allows users to toggle between manual and autofocus modes seamlessly, providing versatility in shooting scenarios. Meanwhile, the VILTROX 35mm f1.7 is equipped with a new STM motor that offers fast and near-silent autofocus, minimizing focus breathing, which is particularly beneficial for video recording. This makes the VILTROX a compelling option for those who frequently capture moving subjects or require smooth transitions in video.
Focal Length Versatility
The Sigma 28-70mm offers a focal length range from 28mm to 70mm, making it an ideal choice for a variety of photography styles, from landscapes to portraits. This zoom capability is perfect for users who desire flexibility in framing their shots without needing to change lenses. Conversely, the VILTROX 35mm f1.7 has a fixed focal length of 35mm, which translates to a natural perspective similar to the human eye. This makes it well-suited for street photography and portraits but may limit users who seek a broader range of compositions.
Minimum Focusing Distance
In terms of minimum focusing distance, the VILTROX 35mm f1.7 shines with a distance of just 0.33 meters (33cm), allowing photographers to capture stunning close-up shots with remarkable detail. This feature adds versatility to the lens, making it a great option for macro-style photography. The Sigma 28-70mm, while not explicitly stated, is designed to offer a high standard of quality across its zoom range. However, the VILTROX's close-focusing capability gives it an edge for specific shooting scenarios where detail is paramount.
Intended Use and Target Audience
The Sigma 28-70mm is primarily targeted towards professional photographers and serious enthusiasts who require a high-performance lens that can handle a variety of shooting situations. Its advanced features and optical quality justify its higher price point. Conversely, the VILTROX 35mm f1.7 is aimed at casual photographers and those on a budget who still want to achieve high-quality images without the hefty price tag. This lens is particularly appealing to those who engage in street photography or portrait work and need a reliable, affordable solution.
Which should you buy?
Ultimately, the choice between the Sigma 28-70mm F2.8 DG DN for Sony E Black and the VILTROX 35mm f1.7 Fuji hinges on your specific needs and budget. If you prioritize versatility, high optical performance, and are willing to invest, the Sigma lens is an excellent choice. However, if you are looking for a more affordable option that still delivers impressive quality, especially in low-light conditions, the VILTROX 35mm f1.7 is a fantastic alternative. Each lens has its strengths, making them suitable for different types of photographers.
