Price Comparison
The Tamron 70-300mm F/4.5-6.3 Di III RXD is priced at $399.00, whereas the VILTROX 35mm F1.7 comes in at a significantly lower price of $179.00. This makes the VILTROX about 55% cheaper than the Tamron. For photographers on a budget, the VILTROX offers an attractive option without sacrificing essential features. However, the higher price of the Tamron reflects its telephoto zoom capabilities and versatility, making it a more suitable choice for those seeking a broader range of shooting options.
Lens Type and Purpose
The Tamron 70-300mm is a telephoto zoom lens designed for full-frame and APS-C Sony mirrorless cameras, making it ideal for capturing distant subjects like wildlife or sports. In contrast, the VILTROX 35mm is a prime lens that excels in portrait and street photography, thanks to its large F1.7 aperture, which creates beautiful bokeh. While the Tamron allows for versatility with its zoom range, the VILTROX is tailored for specific creative applications, often producing sharper images at its fixed focal length.
Autofocus Performance
The autofocus capabilities of both lenses cater to different needs. The Tamron features the RXD (Rapid eXtra-silent stepping Drive) unit, designed for high-speed, quiet autofocus, which is especially beneficial in dynamic shooting environments. Meanwhile, the VILTROX's built-in STM stepping motor also emphasizes efficient and reliable autofocus, supporting eye and face detection for improved tracking. While both lenses provide effective autofocus, the choice between them may depend on whether users prioritize silent operation or advanced tracking capabilities.
Build Quality and Portability
In terms of build quality, the Tamron incorporates moisture-resistant construction, making it suitable for outdoor photography in various weather conditions. On the other hand, the VILTROX is notably lightweight at just 170 g, enhancing its portability for impromptu shooting sessions. The Tamron weighs 19.2 oz, which is relatively light for a telephoto lens, but it is still bulkier than the VILTROX. For photographers who often travel or shoot on the go, the compact design of the VILTROX may be more appealing.
Image Quality
When it comes to image quality, both lenses employ advanced optical designs to minimize aberrations. The Tamron has 15 elements in 10 groups, which helps achieve uncompromising image quality and stunning bokeh. Conversely, the VILTROX features 11 elements in 9 groups, including specialized lenses to enhance clarity and color accuracy. While both lenses produce high-quality images, the Tamron may have the edge in versatility due to its zoom capabilities, whereas the VILTROX excels in creating a distinct artful effect with its large aperture.
Versatility and Use Cases
The Tamron 70-300mm is lauded for its versatility, allowing photographers to cover a wide range of scenarios from landscapes to portraits. Its impressive focal length range makes it suitable for various types of photography, including sports and wildlife. In contrast, the VILTROX 35mm is more specialized, catering to those who prioritize depth of field and artistic blur in their shots. The choice between these lenses depends largely on the photographer's intended use, with the Tamron being the go-to for diverse shooting needs and the VILTROX appealing to those focused on creative portraiture.
Compatibility
Both lenses are designed for Sony E-mount cameras, ensuring compatibility across a wide range of models, including the latest options like the A7IV and FX3. The Tamron is a full-frame lens that also works on APS-C cameras, providing a 105-450mm equivalent field-of-view, making it highly adaptable. The VILTROX, being an APS-C lens, provides a standard field of view for that format, making it less versatile for full-frame shooters. This difference means that users with a mixed camera system may find the Tamron lens to be a more flexible option.
Which should you buy?
Deciding between the Tamron 70-300mm and the VILTROX 35mm ultimately depends on your specific photography needs and budget. The Tamron offers a robust zoom range and exceptional image quality, making it ideal for versatile shooting situations, albeit at a higher price point of $399. Meanwhile, the VILTROX, priced at $179, is an excellent choice for those focused on portraits and street photography, thanks to its large aperture and lightweight design. If budget is a primary concern and you specialize in portraiture, the VILTROX is the way to go. However, for those needing a versatile lens that can adapt to various shooting conditions, the Tamron is the better investment.
