Overview of the EF 85mm f1.8 Portrait Lens
The EF 85mm f1.8 Portrait Lens is priced at $77.59 and is designed for Canon EOS DSLR cameras. This lens is a fully manual focus option, which means it offers photographers precise control over their settings. It features a maximum aperture of f1.8, providing excellent low-light performance and aesthetic bokeh for portrait photography. On the other hand, the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R is priced at $175.99 and offers a versatile zoom range ideal for various shooting scenarios. Its f4.0-5.6 aperture range is less bright than the 85mm lens, but it allows for greater flexibility in framing shots.
Image Quality
The EF 85mm f1.8 Portrait Lens promises superb image quality and charming bokeh, thanks to its six rounded aperture blades and advanced optical technologies. These features help in reducing aberrations and glare, resulting in clear images with a beautiful background blur. In contrast, the OM SYSTEM Olympus M.Zuiko Digital 40-150mm lens, while not specifically noted for its bokeh, provides decent image quality with a maximum image magnification of .16x. However, the Olympus lens's maximum aperture of f4.0-5.6 limits its low-light capability compared to the more capable f1.8 of the Canon lens.
Compatibility
The Canon EF 85mm f1.8 lens boasts wide compatibility with a range of Canon DSLR models, including the EOS Rebel series and professional cameras such as the 5D Mark IV and 1D X. This extensive compatibility makes it a versatile choice for Canon users. Conversely, the OM SYSTEM Olympus M.Zuiko lens is specifically designed for Micro Four Thirds cameras, which limits its use to Olympus and Panasonic models. This distinction may affect photographers who are considering future camera upgrades or switching brands.
Focusing Mechanism
The EF 85mm f1.8 Portrait Lens features a fully manual focus design that allows for precise adjustment of the focal point. This can enhance a photographer's skills and creativity as they learn to control their settings without autofocus assistance. However, it requires a learning curve for those not accustomed to manual focusing. The OM SYSTEM lens, with its High-Speed Imager AF (MSC), offers an advantage in terms of quick and efficient focusing, making it easier for users to capture moving subjects or to shoot in dynamic environments.
Portability
Weighing significantly less than the OM SYSTEM Olympus M.Zuiko Digital lens, the EF 85mm f1.8 Portrait Lens is designed with a focus on portability and ease of use. Its compact design makes it a convenient option for photographers on the go. The Olympus lens, while also portable, is inherently bulkier due to its zoom capabilities. This may make the Canon lens a preferred choice for those who prioritize lightweight gear during their shoots.
Price Comparison
The EF 85mm f1.8 Portrait Lens is priced at $77.59, making it about 56% cheaper than the OM SYSTEM Olympus M.Zuiko Digital 40-150mm lens, which retails for $175.99. This significant price difference could be a major deciding factor for budget-conscious photographers or those just starting out who seek an affordable yet high-quality lens option. The lower price of the Canon lens does not come at the expense of performance, making it an attractive option for many users.
Intended Use
The EF 85mm f1.8 Portrait Lens is particularly well-suited for portrait photography, allowing for stunning background separation and artistic expression. Its manual focus design encourages photographers to engage deeply with their craft. In contrast, the OM SYSTEM Olympus M.Zuiko Digital 40-150mm lens excels in versatility, suitable for various photography styles, including wildlife and sports, thanks to its zoom capabilities. This lens is ideal for photographers who prefer a single lens solution for multiple subjects.
Which should you buy?
Choosing between the EF 85mm f1.8 Portrait Lens and the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R ultimately depends on your specific needs as a photographer. If you prioritize image quality, low-light performance, and are looking for a budget-friendly option, the Canon lens is the clear winner. However, if you value versatility and quick autofocus for various types of photography, the Olympus lens may suit you better. Consider your camera system and the type of photography you engage in most often to make the best choice.
