Olympus M.Zuiko Digital ED 8 25mm F 4 Pro Review | 54 Data compared

However, the primary trade-off of this lens is its modest and constant f4 aperture. This prevents users from achieving a shallow depth of field or significant background isolation, making it less ideal for creamier portraits compared to faster rivals like the Leica 10-25mm f1.7. When background blur is achieved at close focus distances, the bokeh quality is somewhat uninspiring, showing visible outlining and faint onion-ringing. Furthermore, using the wide 8mm end for handheld vlogging with sensor-shift image stabilization introduces some noticeable visual warping in the corners, which requires enabling additional digital stabilization and accepting a subsequent image crop to resolve. Ultimately, despite these minor drawbacks, it stands out as one of the most compelling all-in-one walkaround options available for the system.

The DPReview field review highlights the Olympus M.Zuiko Digital ED 8-25mm F4.0 PRO as a versatile 16-50mm equivalent zoom for Micro Four Thirds, featuring exceptional central sharpness, rapid autofocus, and robust weather-sealing. Its pros include minimal focus breathing, a 0.42x max magnification for close-ups, and the capability to use standard 72mm filters. Conversely, key cons involve a constant F4 aperture that is slow for low-light, a lack of optical stabilization, and busy "soap bubble" bokeh. The lens also produces soft, broad sunstars rather than defined points, and its collapsible design adds weight to smaller bodies.

The Olympus M. Zuiko 8-25mm f/4.0 Pro lens is lauded as a compact, weather-sealed (IPX1) travel lens for Micro Four Thirds systems, offering a versatile 16-50mm equivalent focal range and excellent sharpness up to f/8. Key performance pros include very low distortion, well-controlled chromatic aberration, and a fast, silent autofocus motor with a close-focusing distance of 0.23m. Drawbacks identified in the review include reduced sharpness due to diffraction at small apertures (f/16–f/22), a tendency for flare in challenging light, and a too-light action on the AF/MF clutch ring that can lead to accidental setting changes. While ideal for landscapes, its f/4 constant aperture and MFT sensor size make it less suited for achieving extreme background bokeh. For the full, detailed review, visit ePHOTOzine.

The Oxbow Photo review characterizes the Olympus M.Zuiko 8-25mm f/4 Pro lens as a versatile "one-lens" solution for Micro Four Thirds, offering an impressive 16-50mm equivalent range with exceptional edge-to-edge sharpness. Key advantages include its compact, weather-sealed design, a 72mm front filter thread, fast autofocus, and near-macro capabilities, making it ideal for travel and landscape photography. However, the review notes limitations, including a constant f/4 aperture that restricts low-light performance and noticeable purple flare when shooting directly into the sun. Furthermore, the lens relies on digital correction for significant barrel distortion at 8mm and lacks built-in image stabilization, requiring reliance on in-camera systems. YouTube ·

The Olympus M.Zuiko Digital ED 8-25mm F4 PRO is a highly versatile, premium wide-angle zoom lens designed for Micro Four Thirds cameras. It features an unusually long 16-50mm equivalent focal range and a space-saving retractable design. The lens delivers superb optical quality, rendering sharp details across the entire frame regardless of focal length or aperture. It also boasts rapid, silent autofocus, robust weather-sealed build quality, and impressive close-up capabilities with a 23cm minimum focus distance. Additionally, unlike some ultra-wide options, it includes a 72mm filter thread that makes it highly practical for landscape photographers who use screw-in or square filter systems.

The Photography Life review highlights the Olympus 8-25mm f/4 Pro as an exceptional, sharp, and versatile ultra-wide lens for Micro Four Thirds, featuring robust weather sealing and a 72mm filter-friendly design. Key advantages include its 16-50mm equivalent range and excellent close-up capabilities, though it is limited by a moderate f/4 maximum aperture that is not ideal for low-light action or heavy astrophotography. To achieve maximum sharpness in extreme close-up shots, stopping down to f/7.1 is recommended to correct corner softness.

The Olympus M.Zuiko Digital ED 8‑25mm F4.0 PRO is a unique ultra-wide standard zoom lens designed for Micro Four Thirds cameras, offering an exceptionally useful 16-60mm equivalent focal range. It eliminates the need to swap between two separate lenses by seamlessly transitioning from a 107° ultra-wide field of view to a standard 47° perspective. Optically, the lens delivers stellar real-world performance with remarkably consistent center-to-edge sharpness, excellent contrast, and almost invisible barrel distortion or color fringing. Additional positive features include a short, fast zoom action and a handy customizable L-Fn button. However, the main drawback of this lens is its considerable size and weight. It is quite big and heavy for an F4 constant aperture lens, making it feel clumsy and front-heavy on smaller camera bodies like the E-M5 III or E-P7, though it handles well on the larger E-M1. It utilizes a retracting design to save space, but it becomes even longer when unretracted and fully extended for shooting. Finally, the manual focus ring clutch can be pulled back accidentally when sliding the camera out of a bag, which...

The Olympus M.Zuiko Digital ED 8-25mm f/4 PRO is a highly versatile ultra-wide-to-standard zoom lens designed for Micro Four Thirds cameras, offering a unique 16-50mm equivalent focal range. Its optical construction includes 16 elements in 10 groups, incorporating advanced glass like Super ED and DSA lenses that provide fantastic sharpness, rapid autofocussing, and great close-up macro performance down to 9 inches. The lens introduces a smart locking, retractable barrel design that allows it to remain compact at just 441g during transport. It features premium IPX1-rated weather-sealing, a customizable L.Fn button, a manual focus clutch ring, and a 72mm thread that allows users to use standard screw-on filters—a major convenience missing from its wider sibling, the 7-14mm f/2.8 PRO. Despite its high-quality field performance, the review highlights several structural and optical caveats. While image sharpness remains excellent across most of the frame even wide open at f/4, the lens displays subtle softness in the extreme corners, especially at the 25mm telephoto end, which only improves when stopped down to f/8. Additionally, the external zooming mechanism feels and sounds noticeably more "plasticky,"...

The LensTip review concludes that the Olympus M.Zuiko Digital ED 8-25 mm f/4 PRO is a highly versatile, travel-friendly lens that successfully bridges ultra-wide and standard angles of view. Optically, the lens delivers outstanding sharpness and image quality at the frame center across the entire focal range, alongside good edge sharpness even when wide open at f/4. LensTip highly praises its robust, weather-sealed construction, well-damped mechanics, and a quiet, rapid autofocus system. Furthermore, the lens demonstrates excellent control over optical aberrations, exhibiting negligible longitudinal chromatic aberration, low lateral chromatic aberration, proper coma correction, and a respectable handling of flare against bright backlighting. However, the lens is not without compromise, particularly regarding uncorrected images. The primary drawback identified by LensTip is the exceptionally high barrel distortion on RAW files, reaching an extreme -6.41% at the 8 mm wide end, which relies heavily on digital camera profile correction to fix. Additionally, uncorrected RAW files exhibit noticeable vignetting at 8 mm, which disappears once digital cropping or software corrections are applied. Some users may also note that while its f/4 constant aperture allows...
