The EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is aimed at photographers who need a long-range telephoto option. At $65.69, it is more budget-friendly, being about 18% less expensive than the EF 85mm f1.8 Portrait Lens. It allows for capturing distant subjects with excellent detail, making it suitable for wildlife and landscape photography. Like the 85mm lens, this model is also manual focus and compatible with a variety of Canon DSLR cameras, ensuring a broad appeal to photography enthusiasts.
Image Quality and Performance
When it comes to image quality, the EF 85mm f1.8 Portrait Lens excels with its six rounded aperture blades and internal focus mechanism, delivering stunning clarity and beautiful bokeh effects. This lens is designed for capturing artistic portraits, making it a preferred choice for many professionals. On the other hand, the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens utilizes UMC technology to minimize aberrations and flare, but its performance can vary across the zoom range, especially given its variable aperture (f/8.3 at 420mm and f/16 at 800mm). This distinction makes the 85mm lens more suitable for situations where depth of field and background aesthetics are paramount.
Manual Focus Experience
Both lenses offer a fully manual focus experience, which requires photographers to take control of their settings. The EF 85mm f1.8 encourages precise focus control, allowing for a deeper engagement with the photographic process. Similarly, the EF/EF-S 420-800mm F8.3 also emphasizes manual focus for ultimate creative freedom. However, the 85mm lens may cater more to those looking to refine their portrait skills, while the telephoto lens is more advantageous for capturing distant subjects, showcasing a different style of manual photography.
Compatibility with Canon DSLRs
Both lenses boast wide compatibility with various Canon DSLR models, ensuring that they can be used across a range of cameras. The EF 85mm f1.8 Portrait Lens is compatible with models like the EOS Rebel T8i, T7i, and 5D Mark IV among others, while the EF/EF-S 420-800mm lens shares a similar compatibility spectrum. This feature makes either lens a viable choice for Canon users. However, photographers should consider their specific needs, as the 85mm lens is predominantly suited for portrait work, while the telephoto lens is better for landscape and wildlife photography.
Price and Value Proposition
In terms of pricing, the EF 85mm f1.8 Portrait Lens is listed at $77.59, which is approximately 18% higher than the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens priced at $65.69. While the 85mm lens may seem like a larger investment, its focus on high image quality and portrait capabilities can justify the price for serious photographers. Conversely, the telephoto lens offers a more accessible entry point for those interested in exploring telephoto photography without a significant financial commitment.
Target Audience and Use Cases
The EF 85mm f1.8 Portrait Lens is specifically targeted at portrait photographers who prioritize sharpness and aesthetic background blur. Its features cater to those who wish to enhance their skills in manual focusing and artistic expression. In contrast, the EF/EF-S 420-800mm F8.3 Telephoto Zoom Lens is aimed at wildlife and landscape photographers, given its ability to capture distant subjects effectively. These different target audiences highlight the importance of selecting a lens that aligns with individual photography styles and goals.
Which should you buy?
