Price Comparison

When it comes to pricing, the Tamron 18-300mm F/3.5-6.3 is significantly more expensive than the VILTROX 35mm F1.7. The Tamron lens is priced at $599.00, while the VILTROX lens is available for $179.00. This means that the Tamron lens is about 234% more expensive than the VILTROX lens. If budget is a primary concern, the VILTROX offers a more economical choice without sacrificing essential features.

Lens Type and Versatility

The Tamron 18-300mm is a versatile all-in-one zoom lens, providing a focal length range equivalent to 27mm to 450mm in full-frame terms. This makes it suitable for various photography styles, from wide-angle landscapes to ultra-telephoto shots. In contrast, the VILTROX 35mm is a prime lens with a fixed focal length, ideal for portrait and street photography. While the Tamron offers a broader range and more versatility, the VILTROX may excel in portrait work due to its large aperture.

Aperture and Low-Light Performance

The VILTROX 35mm features a large aperture of F1.7, which allows for beautiful bokeh and enhanced low-light performance. This makes it an excellent choice for capturing dreamy portrait shots with a soft background blur. On the other hand, the Tamron lens has a variable aperture ranging from F3.5 to F6.3, which limits its low-light capabilities compared to the VILTROX. Therefore, if you're often shooting in dimly lit environments or looking for that artistic blur, the VILTROX has a distinct advantage.

Autofocus Technology

The autofocus systems of both lenses cater to different needs. The Tamron 18-300mm is equipped with a VXD linear motor focus mechanism, providing fast and precise autofocus for both stills and video. Meanwhile, the VILTROX 35mm uses a built-in STM stepping motor, which is efficient for precise autofocus and supports eye/face tracking. If quick and reliable autofocus is essential for your shooting style, both lenses have their strengths, but the specific choice may depend on whether you prioritize versatility or prime lens performance.

Build Quality and Portability

In terms of build quality, the Tamron 18-300mm boasts a moisture-resistant construction and a fluorine coating, which protects against dust and water splashes. It's compact for a zoom lens, measuring 4.9 X 2.9 inches and weighing 21.9 ounces. The VILTROX 35mm is lighter at 170 grams and has a compact design, making it very portable for spontaneous photography. While the Tamron offers durability features, the lightweight nature of the VILTROX makes it a more convenient option for travel and everyday shooting.

Optical Performance

The Tamron lens incorporates special optical elements arranged to maintain high resolution from edge to edge, ensuring excellent image quality. It also features a minimum object distance of 5.9 inches at 18mm, allowing for close-up photography. The VILTROX 35mm lens includes 11 elements in 9 groups with advanced coatings for enhanced clarity. Although both lenses promise high optical performance, the Tamron’s zoom capability gives it an edge in versatility, while the VILTROX's prime design may offer sharper images, especially in its optimal focal range.

Target Audience

The choice between these two lenses largely depends on the target audience. The Tamron 18-300mm is tailored for photographers who require flexibility and a wide range of focal lengths for various shooting scenarios, making it ideal for travel photographers and hobbyists. Conversely, the VILTROX 35mm is perfect for those who favor portrait and street photography, seeking a high-quality lens that excels in creating a beautiful background blur. Understanding your photographic needs will guide your decision between these two distinct options.

Which should you buy?

Ultimately, the decision between the Tamron 18-300mm F/3.5-6.3 and the VILTROX 35mm F1.7 boils down to your specific photography needs and budget. If you're looking for versatility and the ability to shoot in a wide range of scenarios, the Tamron lens may be worth the investment at $599.00. However, if you're focused on portraits and low-light photography, the VILTROX lens offers excellent performance and value at just $179.00. Each lens has its unique strengths, making your choice contingent on your photography style and budget constraints.
