The Canon EF-S 18-135mm f/3.5-5.6 IS STM and the EF 85mm f1.8 Portrait Lens cater to different photography needs and styles. The former is a versatile zoom lens ideal for a variety of shooting scenarios, while the latter is a specialized portrait lens designed for manual focus. Understanding their unique features will help determine which lens better suits your photography requirements.
Price Comparison
The Canon EF-S 18-135mm f/3.5-5.6 IS STM retails for $329.95, while the EF 85mm f1.8 Portrait Lens is priced significantly lower at $77.59. This makes the EF 85mm lens about 77% cheaper than the 18-135mm lens. The substantial price difference indicates that the EF 85mm lens may be a more accessible option for those on a budget or just starting with portrait photography. However, the higher price of the 18-135mm lens reflects its versatility and advanced features.
Lens Type and Focusing Mechanism
The Canon EF-S 18-135mm is an autofocus lens featuring an inner focusing system that allows for high-speed autofocus, making it suitable for both video and still photography. In contrast, the EF 85mm f1.8 Portrait Lens is fully manual focus, requiring the user to adjust settings like shutter speed, ISO, and aperture manually. This manual focus can provide greater creative control and stability, but it may also pose a learning curve for beginners. The choice between autofocus and manual focus is crucial depending on your comfort level and shooting style.
Image Quality and Performance
In terms of image quality, the Canon EF-S 18-135mm f/3.5-5.6 IS STM is designed to deliver high-resolution images with one UD and one PMO aspheric lens that reduces chromatic aberration. It offers impressive performance with refined Image Stabilization that provides up to four equivalent stops of shake correction. Meanwhile, the EF 85mm f1.8 Portrait Lens promises superb image quality with its hybrid aspherical lens and ultra multi-coating technology, which minimizes aberrations and glare. Both lenses excel in their respective domains, but the 18-135mm lens offers more versatility for varied shooting conditions.
Compatibility and Use Cases
The Canon EF-S 18-135mm f/3.5-5.6 IS STM is compatible with Canon EOS Rebel DSLR cameras, making it a great choice for users of these models who desire a lens that can handle a wide range of photography styles, from landscapes to portraits. On the other hand, the EF 85mm f1.8 Portrait Lens is compatible with a broader range of Canon DSLRs, including models from the EOS series and the Digital Rebel lineup. While the 18-135mm lens is ideal for general use, the 85mm lens shines specifically in portrait photography, allowing for artistic expression through its sharp focus and beautiful bokeh.
Build and Design
The design of the Canon EF-S 18-135mm f/3.5-5.6 IS STM focuses on practicality, featuring a zoom ring lock to prevent accidental extension and a compact size that makes it easy to carry. It weighs 16.9 oz, which is manageable for extended shooting sessions. In contrast, the EF 85mm f1.8 Portrait Lens emphasizes a professional manual experience, with a focus ring designed for precise adjustments. While the 85mm lens is lighter at 1.76 lbs, its manual nature may appeal more to photographers looking for an immersive shooting experience rather than convenience.
Versatility vs. Specialization
The Canon EF-S 18-135mm f/3.5-5.6 IS STM offers broad versatility, suitable for various photography styles, which is particularly beneficial for those who may not want to invest in multiple lenses. Its focal length range allows for wide-angle to moderate telephoto shots, making it an all-in-one solution for everyday photography needs. Conversely, the EF 85mm f1.8 Portrait Lens is specialized for portrait photography, delivering stunning results in that realm but lacking the flexibility found in the zoom lens. If your primary focus is on portrait photography, the 85mm lens might be the superior choice despite its limitations.
Which should you buy?
Ultimately, the decision between the Canon EF-S 18-135mm f/3.5-5.6 IS STM and the EF 85mm f1.8 Portrait Lens comes down to your specific photography needs. If you seek a versatile lens that covers a wide range of shooting scenarios and advanced features, the 18-135mm lens is worth the investment at $329.95. However, if your primary interest lies in portrait photography and you prefer manual focus for creative control, the EF 85mm lens at $77.59 is an excellent, budget-friendly option. Consider your style, preferences, and the types of photography you wish to pursue to make the best choice.
