This lens is specifically designed for Nikon Z series cameras, catering to portrait photographers with its wide f/2.0 aperture.

The lens is constructed with 10 elements in 8 groups, which include Extra-low Dispersion (ED) elements to improve sharpness and color accuracy. Its compact and lightweight design enhances portability, making it a great option for extended shooting sessions.
Image Quality Comparison
The Canon EF-S 18-135mm f/3.5-5.6 is STM excels in versatility, providing high-quality images across a wide focal range. With its refined optical design, it minimizes chromatic aberration and delivers high resolution, especially at the telephoto end. The VILTROX 85mm F2.0 Z Lens, meanwhile, is engineered for portraiture, emphasizing sharpness and color fidelity. Its f/2.0 aperture not only improves low-light performance but also creates a desirable bokeh effect that enhances portraits. While both lenses offer strong performance, the choice largely depends on the type of photography you prefer.
Autofocus Performance
The autofocus capabilities of both lenses are impressive, yet they cater to different needs. The Canon EF-S 18-135mm f/3.5-5.6 is STM features an Inner focusing system and a stepping motor that allows for smooth and quiet autofocus, making it suitable for video work as well as still photography. On the other hand, the VILTROX 85mm F2.0 Z Lens also utilizes a Stepping Motor (STM) for precise and quiet autofocus, optimizing it for both photography and video. Each lens offers reliable autofocus performance, but the Canon lens may have an edge in versatility across various shooting scenarios.
Build and Design
The Canon EF-S 18-135mm f/3.5-5.6 is STM weighs 16.9 oz., making it somewhat heavier than the VILTROX 85mm F2.0 Z, which weighs only 360g (approximately 12.7 oz). The VILTROX lens is designed to be compact and lightweight, measuring φ69mm x 78mm, which makes it a convenient option for long shooting sessions. The Canon lens, while slightly bulkier, includes a zoom ring lock to prevent accidental extension, which can be particularly useful when transporting the lens. If portability is a key factor for you, the VILTROX lens may be the better option.
Versatility in Use
The Canon EF-S 18-135mm f/3.5-5.6 is STM is highly versatile, making it suitable for a range of photography styles, from landscapes to portraits and even action shots. Its zoom range allows photographers to adapt quickly to changing scenes without needing to switch lenses. In contrast, the VILTROX 85mm F2.0 Z Lens is more specialized, excelling in portrait photography but lacking the flexibility of a zoom lens. Thus, if you’re looking for a one-lens solution for various situations, the Canon lens may be more appealing.
Price Considerations

This price difference of about $54.95 means that the VILTROX lens is approximately 17% cheaper than its Canon counterpart. For photographers on a budget or those who primarily focus on portrait photography, the VILTROX offers excellent value without sacrificing essential features. However, the Canon lens justifies its higher price with greater versatility and an advanced image stabilization system.
Which should you buy?
Choosing between the Canon EF-S 18-135mm f/3.5-5.6 is STM and the VILTROX 85mm F2.0 Z Lens ultimately depends on your photographic needs. If you require a versatile lens that can handle a variety of shooting scenarios, the Canon lens is the better option, despite its higher price. However, if you are focused on portrait photography and prefer a compact and lightweight design, the VILTROX provides excellent performance at a more affordable price. Consider your specific requirements and shooting style to make the best choice for your photography endeavors.
