Build Quality

In terms of build quality, the Tamron 70-180mm F/2.8 Di III VC VXD G2 excels with its moisture-resistant construction and fluorine coating. This makes it more suitable for outdoor photography, especially in challenging weather conditions. The Canon EF-S 18-135mm f/3.5-5.6 is STM, while well-constructed, does not feature the same level of environmental protection as the Tamron lens. Both lenses offer a zoom lock mechanism to prevent accidental extension, but the robust design of the Tamron makes it a better choice for professionals who demand durability from their gear.

Image Stabilization

The Canon EF-S 18-135mm f/3.5-5.6 is STM features a refined image stabilization system that delivers up to four equivalent stops of shake correction. This is particularly beneficial for handheld shooting and video work. On the other hand, the Tamron 70-180mm F/2.8 Di III VC VXD G2 is equipped with TAMRON’s proprietary VC (Vibration Compensation) mechanism, which also aims to enhance shooting stability. While both lenses offer effective stabilization, the Canon lens targets a broader audience with its well-rounded performance in various shooting scenarios, whereas the Tamron lens is designed for those who prioritize high-speed performance and precision.

Autofocus Performance

The Tamron 70-180mm F/2.8 Di III VC VXD G2 boasts a high-speed and high-precision autofocus system driven by its VXD linear motor focus mechanism. This offers improved subject tracking, making it ideal for fast-paced photography such as sports or wildlife. In contrast, the Canon EF-S 18-135mm f/3.5-5.6 is STM utilizes an inner focusing system and optimized AF algorithm, providing decent autofocus performance for both stills and video. While the Canon lens is adequate for general photography, the Tamron lens stands out for its advanced autofocus capabilities, catering to serious photographers.

Versatility

The Canon EF-S 18-135mm f/3.5-5.6 is STM is a versatile lens with a focal length range that supports a wide variety of shooting styles, from landscapes to portraits. It also offers a maximum magnification of 0.28x at the telephoto end. Conversely, the Tamron 70-180mm F/2.8 Di III VC VXD G2 covers a longer focal length, reaching up to 180mm, providing greater reach for distant subjects. This makes the Tamron lens particularly appealing for wildlife and sports photography. Ultimately, the choice between the two lenses will depend on the photographer's needs for versatility and focal length range.

User Experience

The Canon EF-S 18-135mm f/3.5-5.6 is STM is designed with user-friendly features, including a zoom ring lock that prevents accidental extension. This can be particularly helpful for photographers on the go. Meanwhile, the Tamron 70-180mm F/2.8 Di III VC VXD G2 supports the dedicated TAMRON Lens Utility™ and TAMRON Lens Utility Mobile™ apps, allowing users to customize functions based on their shooting style. While both lenses offer a good user experience, the Tamron lens provides advanced customization options that may appeal to tech-savvy users looking for a more tailored shooting experience.

Conclusion on Optical Quality

When it comes to optical quality, both lenses are engineered to deliver high-resolution images with reduced chromatic aberration. The Canon EF-S 18-135mm f/3.5-5.6 is STM incorporates one UD and one PMO aspheric lens for improved image quality throughout its zoom range. The Tamron 70-180mm F/2.8 Di III VC VXD G2, with its revamped optical design, aims for uncompromising image quality across its focal range. While both lenses perform admirably, the Tamron's faster aperture of f/2.8 allows for better low-light performance and shallower depth of field, offering more creative possibilities for photographers.

Your choice between the Canon EF-S 18-135mm f/3.5-5.6 is STM and the Tamron 70-180mm F/2.8 Di III VC VXD G2 should hinge on your specific needs and budget.
