Introduction to the Lenses
In the world of photography, selecting the right lens can significantly impact your creative output. The 85mm f1.8 Portrait Lens for Nikon and the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R are two distinct options catering to different photographic needs. While the Nikon lens is designed for portrait and close-up photography, the Olympus lens offers versatility with its zoom capabilities. Understanding their features will help you make an informed choice.
Lens Type and Focusing Mechanism
The 85mm f1.8 Portrait Lens is a manual focus lens, requiring photographers to adjust focus manually. This can be an advantage for those who prefer a hands-on approach, allowing for precise control over focus and depth of field. However, this lens will not work in auto-focus mode, and users need to set their cameras to manual mode to avoid errors. In contrast, the OM SYSTEM Olympus M.Zuiko lens features a high-speed imager AF (MSC), making it more user-friendly for those who prefer quick adjustments and automatic focusing. This difference highlights the Nikon lens's targeted use for dedicated portrait photographers versus the Olympus lens's broader appeal for casual users and various photography styles.
Aperture and Depth of Field
The 85mm f1.8 Portrait Lens boasts a large aperture of f1.8, which is ideal for creating stunning background bokeh and achieving a shallow depth of field. This feature is particularly beneficial for portraiture, where isolating the subject from the background is essential. On the other hand, the OM SYSTEM Olympus lens has a maximum aperture of f4.0-5.6, which limits its ability to produce the same level of background blur. Therefore, for photographers focused on achieving dramatic portrait effects, the Nikon lens stands out as the more capable option.
Focal Length Versatility
The focal length of a lens determines its versatility and suitability for various types of photography. The 85mm f1.8 lens is fixed, making it ideal for half-body and full-body portraits, as well as detailed close-ups. This fixed focal length allows for a natural perspective in portrait photography. Conversely, the OM SYSTEM Olympus lens offers a focal length range of 40-150mm, providing a 3.75x zoom capability. This feature allows photographers to capture subjects at various distances, making it a more flexible choice for landscape, wildlife, or event photography.
Image Quality and Performance
Both lenses are designed to deliver high-quality images, but their performance will vary based on usage. The 85mm f1.8 lens is specifically engineered for Nikon DSLRs and is compatible with a wide range of Nikon models. Its design focuses on portrait photography, ensuring that images are sharp and rich in detail. Meanwhile, the OM SYSTEM Olympus lens is compatible with Micro Four Thirds cameras, making it suitable for users of Olympus and Panasonic systems. Though it may not provide the same level of background separation as the Nikon lens, its zoom capability allows for diverse shooting scenarios.
Portability and Design
When it comes to design and portability, the OM SYSTEM Olympus lens has an advantage with its lightweight and portable characteristics. Weighing less than the 85mm f1.8 lens, the Olympus lens is easier to carry for extended periods, making it suitable for travel and outdoor photography. The Nikon lens, while not excessively heavy, is more substantial due to its build and larger glass elements. For photographers who prioritize portability for on-the-go shooting, the Olympus lens is the better option.
Pricing Comparison
The 85mm f1.8 Portrait Lens is priced at $96.22, making it a cost-effective choice for those specifically looking for a portrait lens. In contrast, the OM SYSTEM Olympus lens is priced at $175.99, about 83% more expensive than the Nikon option. This price difference may be justified by the Olympus lens's zoom functionality and versatility, but for dedicated portrait photographers, the Nikon lens presents a more budget-friendly alternative.
Which should you buy?
Choosing between the 85mm f1.8 Portrait Lens for Nikon and the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R ultimately depends on your photographic needs. If you are primarily focused on portraiture and desire a lens that excels in creating beautiful bokeh, the Nikon lens is the superior choice. However, if you prefer a versatile zoom lens that accommodates a variety of shooting situations, the Olympus lens may be more suitable. Consider your photography style and budget to determine which lens will enhance your creative pursuits.
