Price Comparison

The Canon EF-S 18-55mm f/3.5-5.6 is II SLR Lens White Box is significantly more affordable than the Canon EF-S 18-135mm f/3.5-5.6 is STM. Priced at $134.95, the 18-55mm lens costs about 59% less than the 18-135mm lens, which is priced at $329.95. This substantial price difference makes the 18-55mm lens an attractive option for budget-conscious photographers seeking a reliable zoom lens without breaking the bank.

The lower price of the 18-55mm lens does not compromise its quality. Canon has equipped this lens with Optical Image Stabilizer technology, allowing for sharper images even in lower light conditions. This makes it a practical choice for those who may be just starting in photography or need a dependable lens for everyday shooting.

Focal Length and Versatility

When it comes to focal length, the Canon EF-S 18-135mm f/3.5-5.6 is STM offers a broader range than the Canon EF-S 18-55mm f/3.5-5.6 is II. The 18-135mm lens covers a focal length of 18mm to 135mm, making it versatile for both wide-angle shots and telephoto images. This allows photographers to capture a wide variety of scenes, from landscapes to portraits, without needing to switch lenses.

In contrast, the 18-55mm lens has a more limited range, making it suitable primarily for standard wide-angle to short telephoto photography. While it is great for everyday use, photographers looking for more flexibility in their shooting options may find the 18-135mm lens to be the better choice.

Image Stabilization Features

Both lenses feature image stabilization, but the Canon EF-S 18-135mm f/3.5-5.6 is STM takes it a step further. It utilizes a refined Image Stabilization system that delivers up to four equivalent stops of shake correction throughout the zoom range. This capability is particularly beneficial for videographers, as it supports the Movie Servo AF feature on Canon DSLR cameras, providing smooth and quiet focusing during video recording.

The Canon EF-S 18-55mm f/3.5-5.6 is II also provides effective stabilization, allowing sharp handheld shots at shutter speeds up to four stops slower. While both lenses perform well in this regard, the advanced features of the 18-135mm lens make it a superior option for those who prioritize video quality and stability.

Build Quality and Design

In terms of build quality, the Canon EF-S 18-135mm f/3.5-5.6 is STM is designed with more sophisticated engineering, featuring an inner focusing system and a zoom ring lock that prevents accidental extension of the lens. This thoughtful design enhances the user experience and ensures the lens remains compact and easy to handle.

On the other hand, the Canon EF-S 18-55mm f/3.5-5.6 is II, while still solidly built, does not offer these advanced design features. It consists of 11 elements in 9 groups and is lightweight, making it convenient for everyday use. However, for those who appreciate a more robust and professional feel, the 18-135mm lens stands out in terms of quality and practicality.

Autofocus Performance

The autofocus performance of the Canon EF-S 18-135mm f/3.5-5.6 is STM is enhanced by its high-speed CPU and optimized AF algorithm, offering quick and accurate focusing. This lens is particularly tailored for capturing fast-moving subjects, making it suitable for both sports and wildlife photography.

In comparison, the Canon EF-S 18-55mm f/3.5-5.6 is II features a gear-driven focus adjustment system. While it provides reliable autofocus for general photography, it may not be as swift or responsive as the STM technology found in the 18-135mm lens. Photographers needing rapid autofocus for dynamic scenes may find the 18-135mm lens to be a more effective tool.

Optical Performance

Both lenses are designed to deliver excellent optical performance, but the Canon EF-S 18-135mm f/3.5-5.6 is STM incorporates advanced lens elements, including one UD and one PMO aspheric lens. This design minimizes chromatic aberration and enhances image quality throughout the zoom range, providing high-resolution and high-contrast images.

The Canon EF-S 18-55mm f/3.5-5.6 is II also offers good optical quality, utilizing a spherical lens element to correct aberration. While it performs admirably for everyday photography, the optical superiority of the 18-135mm lens makes it a more appealing choice for professionals or enthusiasts who demand the highest image quality.

Conclusion

In conclusion, both the Canon EF-S 18-135mm f/3.5-5.6 is STM and the Canon EF-S 18-55mm f/3.5-5.6 is II SLR Lens White Box have their unique advantages. The 18-135mm lens stands out with its versatility, advanced image stabilization, superior autofocus performance, and enhanced optical quality, making it ideal for serious photographers and videographers. However, its higher price may not appeal to everyone.

On the other hand, the 18-55mm lens offers great value for its price, making it an excellent choice for beginners or those who primarily shoot standard wide-angle and short telephoto images. Ultimately, the decision comes down to your specific photography needs and budget.

Which should you buy?

If you're looking for a versatile, high-quality lens and are willing to invest more, the Canon EF-S 18-135mm f/3.5-5.6 is STM is the clear choice.
