Price Comparison
The Canon EF-S 18-135mm f/3.5-5.6 IS STM is priced at $329.95, while the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R is significantly cheaper at $175.99. This means that the Olympus lens is about 46% less expensive than the Canon lens. For those who are budget-conscious or are looking to save on camera accessories, the Olympus option is a clear winner in this category. The price difference can be substantial for amateur photographers or those just starting out, allowing them to invest in additional gear or photography experiences.
Zoom Range
The Canon EF-S 18-135mm offers a versatile zoom range from 18mm to 135mm, making it suitable for a variety of shooting scenarios—from wide landscapes to distant subjects. In contrast, the Olympus lens has a zoom range of 40mm to 150mm, which, while still versatile, does not cover as wide an angle as the Canon. This difference in zoom range equates to the Canon lens being more adaptable for diverse photography styles. Photographers who require both wide-angle and telephoto capabilities in one lens may find the Canon's range more appealing.
Aperture Performance
The Canon EF-S 18-135mm has a maximum aperture of f/3.5-5.6, while the Olympus M.Zuiko Digital 40-150mm has a maximum aperture of f/4.0-5.6. This slight difference may seem negligible, but it does imply that the Canon lens can gather more light at the wide end, potentially resulting in better low-light performance. However, both lenses exhibit similar performance at the telephoto end, where both peak at f/5.6. For photographers frequently shooting in varying light conditions, the Canon may provide a slight edge.
Autofocus Technology
The Canon EF-S 18-135mm features an inner focusing system that supports high-speed autofocus, especially beneficial for video shooting due to its compatibility with Canon's Movie Servo AF. The Olympus M.Zuiko uses a High-Speed Imager AF (MSC) for quick focusing. While both lenses are designed for efficient autofocus, the Canon lens is specifically tailored for video applications with its refined focusing system, which could be a critical factor for videographers. Users focused on video production may prefer the Canon for its advanced autofocus capabilities.
Image Stabilization
The Canon EF-S 18-135mm lens includes a refined Image Stabilization system that provides up to four equivalent stops of shake correction throughout its zoom range. This feature can be particularly advantageous for handheld shooting, reducing the risk of motion blur. In contrast, the description does not mention any image stabilization in the Olympus lens. For photographers who often shoot in dynamic environments or at slower shutter speeds, the Canon's superior stabilization could lead to significantly sharper images.
Build Quality and Design
The Canon EF-S 18-135mm is designed to be compact and lightweight, weighing in at 16.9 oz, and features a zoom ring lock to prevent accidental extension. The Olympus M.Zuiko, while also portable, is noted for its sleek silver design and is specifically made for Micro Four Thirds cameras. Both lenses prioritize portability, but the Canon's zoom ring lock adds an extra layer of security for traveling photographers. Those who prioritize build quality and robust features may find the Canon's design more appealing.
Versatility and Use Cases
The Canon EF-S 18-135mm lens is often favored for its versatility, making it suitable for both still photography and videography. Its wide zoom range allows for creative flexibility, from capturing landscapes to portraits. The Olympus M.Zuiko lens, while also versatile, is more limited in its focal length range, making it best suited for medium telephoto work. Photographers looking for an all-in-one solution may prefer the Canon, while those focused mainly on portraits or distant subjects may find the Olympus sufficient for their needs.
Which should you buy?
Choosing between the Canon EF-S 18-135mm f/3.5-5.6 IS STM and the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R ultimately depends on your specific needs and budget. The Canon lens, while more expensive at $329.95, offers a wider zoom range, superior image stabilization, and enhanced autofocus capabilities, making it ideal for both photography and videography. On the other hand, the Olympus lens at $175.99 provides a more budget-friendly option without sacrificing too much in terms of quality, particularly for those focused on medium telephoto shots. If budget is a primary concern, the Olympus is a solid choice, but for versatility and advanced features, the Canon stands out as the better investment.
