Overview of VILTROX AF 28mm F4.5 XF Pancake Lens

The VILTROX AF 28mm F4.5 XF Pancake Lens stands out for its ultra-lightweight design and compact size, weighing only 60 grams and measuring 15.3mm thick. At a price of $99.00, this lens is about 70% cheaper than the Canon offering. It is specifically designed for Fuji X-mount cameras, making it a great option for photographers who prioritize portability without sacrificing image quality. With unique features like a slide cap design that transforms into a lens, it adds a fun twist to the shooting experience.

Image Quality Comparison

The Canon EF-S 18-135mm f/3.5-5.6 is STM offers exceptional image quality with its use of one UD and one PMO aspheric lens, effectively reducing chromatic aberration. This results in high-resolution and high-contrast images across its zoom range. In contrast, the VILTROX AF 28mm F4.5 XF features six elements in six groups, including two ED lenses and two aspherical lenses, ensuring sharp and vibrant images. While both lenses promise high-quality output, the Canon lens’s zoom capability gives it an edge in versatility, allowing for various focal lengths and compositions.

Autofocus Performance

When it comes to autofocus, the Canon EF-S 18-135mm lens features an inner focusing system, which, combined with a high-speed CPU and optimized AF algorithm, facilitates quick and reliable focusing. This system is particularly useful for video shooting, supporting smooth and quiet autofocus transitions. On the other hand, the VILTROX AF 28mm lens incorporates a built-in VCM motor, providing efficient autofocus performance that supports face and eye recognition. While both lenses excel in this area, the Canon's advanced inner focusing system may offer a more seamless experience for videographers.

Portability and Design

The VILTROX AF 28mm F4.5 XF excels in terms of portability, being the lightest and thinnest lens in its category. This makes it an excellent choice for on-the-go shooting and vlogging, especially for those who prioritize a compact setup. In contrast, the Canon EF-S 18-135mm lens, while still relatively compact, is bulkier at 16.9 ounces and measures 3.1 x 3.8 inches. Therefore, if you require a lens that is easy to carry around, the VILTROX lens is the clear winner in terms of design and portability.

Versatility in Shooting

The Canon EF-S 18-135mm lens offers a versatile focal length range of 18-135mm, making it suitable for a wide range of shooting scenarios, from landscapes to portraits. This adaptability is a significant advantage for photographers who want an all-in-one lens. The VILTROX AF 28mm lens, while excellent for wide-angle perspectives, is limited to a fixed 28mm focal length. This makes it less versatile for various types of photography, particularly when a zoom feature is needed. Photographers looking for flexibility in their shooting will find the Canon lens more appealing.

Price and Value

At $329.95, the Canon EF-S 18-135mm lens is a significant investment compared to the VILTROX AF 28mm lens, which is priced at $99.00. This equates to a difference of about $230, making the VILTROX lens approximately 70% cheaper. While the Canon lens offers advanced features and versatility, the VILTROX lens provides excellent value for those who primarily shoot with a Fuji X-mount camera and are looking for an affordable, high-quality lens for everyday use.

Which should you buy?

Ultimately, the decision between the Canon EF-S 18-135mm f/3.5-5.6 is STM and the VILTROX AF 28mm F4.5 XF depends on your specific photography needs. If you require a versatile lens with excellent image quality and advanced autofocus for both stills and video, the Canon lens is worth the investment. However, if you prioritize portability, affordability, and are primarily shooting with a Fuji X-mount camera, the VILTROX lens provides great value without compromising on quality.
