Optical Performance
When it comes to optical performance, both lenses showcase impressive designs aimed at delivering high-quality images. The Tamron 17-70mm f/2.8 features an optical construction of 16 elements in 12 groups, including two Glass Molded Aspherical lens elements and one hybrid aspherical lens element. This setup enables outstanding image quality across its zoom range.
On the other hand, the VILTROX 9mm F2.8 is built with 13 elements in 11 groups, including 3 High Refractive elements and 3 Extra-low Dispersion elements. This combination helps achieve sharp images from the center to the edge of the frame. While the Tamron excels in zoom versatility, the VILTROX offers a specialized design for capturing wide vistas or dynamic scenes, delivering vibrant imagery.
Low-Light Capability
In low-light conditions, the maximum aperture of f/2.8 across the entire focal length of the Tamron provides consistent brightness, making it effective for various lighting scenarios. This feature is especially useful for photographers who often shoot in dimly lit environments.
Conversely, the VILTROX also features a maximum aperture of f/2.8, which allows for similar low-light performance as the Tamron. However, its wider field of view enhances its functionality in capturing expansive scenes and details in low light. Both lenses perform admirably, but the Tamron's zoom capability may offer more flexibility in challenging lighting.
Focusing Capabilities
The Tamron 17-70mm f/2.8 is equipped with an upgraded VC (Vibration Compensation) system that enhances stabilization, particularly beneficial for video shooting. The close-focusing capability is noteworthy, with a minimum focusing distance of just 7.5 inches at 17mm and 15.4 inches at 70mm. This feature allows for creative close-up shots.
In contrast, the VILTROX 9mm F2.8 boasts a minimum focusing distance of only 0.13 meters (13cm), enabling stunning close-up photography. Its reliable autofocus system, powered by an STM motor, ensures quick and precise focus, making it ideal for capturing fast-moving subjects.
