It features an impressive 113.8° field of view, equivalent to 13.5mm on a full-frame camera, making it ideal for capturing expansive landscapes and tight interiors. This lens has a large F2.8 aperture, which allows for better performance in low-light conditions. It also includes advanced Eye and Face Detection autofocus, ensuring that your subjects remain sharp, even in fast-paced scenarios, thus enhancing its appeal for vloggers and dynamic photographers alike.
Price Comparison
When considering price, the OM SYSTEM Olympus lens is about 12% cheaper at $175.99 compared to the VILTROX lens, which retails for $199.00. For those on a budget or looking for a cost-effective option, the Olympus lens may present a more appealing choice. However, the slightly higher price of the VILTROX lens could be justified by its ultra-wide capabilities and advanced features that cater to specific shooting needs, such as vlogging and landscape photography.
Focal Length and Versatility
The focal length is a critical factor in lens selection. The OM SYSTEM Olympus lens offers a focal length of 40-150mm, providing versatility suitable for portrait and wildlife photography due to its zoom capabilities. On the other hand, the VILTROX lens has a fixed focal length of 9mm, which is ultra-wide and excels in capturing vast scenes and interior spaces. This difference in focal length means that the Olympus lens can serve multiple photography styles, while the VILTROX lens is specialized for those who need an expansive field of view.
Aperture and Low-Light Performance
The VILTROX lens features a large aperture of F2.8, which is advantageous for low-light photography, allowing more light to hit the sensor and enabling slower shutter speeds to reduce motion blur. In contrast, the OM SYSTEM Olympus lens has a maximum aperture of F4-5.6, which is less effective in dim conditions. This difference makes the VILTROX lens better suited for nighttime photography and other low-light scenarios, allowing photographers to capture cleaner, more detailed images with less noise.
Autofocus Capabilities
Autofocus performance varies between these lenses. The OM SYSTEM lens features High-Speed Imager AF (MSC) for quick focusing, making it reliable for action shots. However, the VILTROX lens enhances this with Eye and Face Detection autofocus technology, ensuring that subjects remain sharp and clear. This feature is particularly beneficial for portrait and vlog-style shooting, where maintaining focus on moving subjects is crucial. Thus, while both lenses offer good autofocus systems, the VILTROX lens may provide an edge in dynamic shooting situations.
Design and Portability
In terms of design, the OM SYSTEM Olympus lens is specifically noted for its portability, making it a great option for photographers who travel frequently or shoot on location. The VILTROX lens, while compact, focuses more on performance with its advanced features and optical design. Both lenses have their strengths; however, if portability is a top priority, the Olympus lens may be the more suitable choice due to its lightweight and compact design.
Which should you buy?
Choosing between the OM SYSTEM Olympus M.Zuiko Digital 40-150mm and the VILTROX 9mm F2.8 E-Mount lens ultimately depends on your specific needs as a photographer. If you require versatility and a budget-friendly option, the Olympus lens stands out with its reasonable price and zoom capabilities. However, if you're focused on capturing ultra-wide shots with excellent low-light performance and advanced autofocus features, the VILTROX lens may justify its higher price. Both lenses have distinct advantages, so consider your shooting style and requirements to make the best choice.
