Introduction to the Lenses
The Tamron 17-70mm f/2.8 Di III-A VC RXD Lens for Sony E APS-C Mirrorless Cameras and the VILTROX PRO 27mm F1.2 XF Fuji for Fujifilm x Mount are two compelling options for photographers looking to enhance their lens collection. Each lens offers unique features that cater to different shooting styles and preferences. The Tamron lens is priced at $599.00, while the VILTROX lens is slightly cheaper at $578.00, making it about 3.5% less expensive.
Optical Performance
When it comes to optical performance, the Tamron lens features 16 elements in 12 groups, including two Glass Molded Aspherical elements and one hybrid aspherical element. This design aims to provide outstanding image quality across its 4.1x zoom range. On the other hand, the VILTROX lens is built with 15 glass elements in 11 groups, which allows for exceptional resolution and reduced chromatic aberrations. Both lenses deliver impressive optical quality; however, the Tamron lens offers a zoom capability that the VILTROX cannot match.
Aperture and Depth of Field
The Tamron lens has a maximum aperture of f/2.8, which allows for good low-light performance and a decent depth of field control. In contrast, the VILTROX lens boasts a much larger maximum aperture of f/1.2. This feature enables photographers to produce a more pronounced bokeh effect, making it particularly appealing for portrait photography. The ability to create creamy backgrounds with the VILTROX lens may sway those who prioritize aesthetic depth of field in their work.
Focal Length Versatility
The Tamron lens provides a focal length range of 17-70mm, translating to a full-frame equivalent of 25.5-105mm. This versatility makes it suitable for a wide array of photography styles, from landscapes to portraits. The VILTROX lens, with its fixed 27mm focal length (approximately 40mm equivalent), is more specialized but offers a natural perspective ideal for street photography and everyday snapshots. If versatility is a priority, the Tamron lens stands out; however, the VILTROX lens excels in its specific applications.
Autofocus Capabilities
Autofocus performance is another significant differentiator. The Tamron lens features an upgraded VC (Vibration Compensation) system that works effectively with Sony APS-C mirrorless cameras, enhancing video shooting stability. Meanwhile, the VILTROX lens prides itself on precise and fast autofocus, supporting eye focus and EXIF information transmission. Both lenses are designed for quick shooting, but if you are focused on video capabilities, the Tamron lens may be the better choice.
Build Quality and Weather Resistance
In terms of build quality, the Tamron lens is equipped with moisture-resistant construction and a fluorine coating, enhancing its durability in various shooting conditions. The VILTROX lens does not highlight any specific weather-sealing features. For photographers who often shoot in challenging environments, the Tamron’s robust design provides greater peace of mind, making it a stronger candidate for outdoor photography.
Minimum Focus Distance
The Tamron lens has a minimum focusing distance of 7.5 inches at 17mm and 15.4 inches at 70mm, allowing for close-up shots that capture fine details. On the other hand, the VILTROX lens offers a minimum focusing distance of 11 inches (28cm), which still provides a reasonable range for dynamic composition. While both lenses allow for creative shots, the Tamron lens gives you a slight edge in close focusing capabilities.
Which should you buy?
Choosing between the Tamron 17-70mm f/2.8 Di III-A VC RXD Lens and the VILTROX PRO 27mm F1.2 XF Fuji largely depends on your specific photography needs. If you seek versatility, excellent optical performance, and strong video capabilities, the Tamron lens is the clear winner at $599.00. However, if you prioritize a large aperture for beautiful bokeh and a more natural perspective for street and portrait photography, the VILTROX lens at $578.00 is a compelling alternative. Ultimately, your decision should reflect the types of photography you intend to pursue.
