Olympus M.Zuiko ED 12 50mm F3 5 6 3 EZ Review | 54 Data compared

The Imaging Resource review identifies the Olympus 12-50mm f/3.5-6.3 EZ M.Zuiko Digital ED as a versatile, weather-sealed kit lens featuring a three-position zoom with electronic, manual, and macro modes, offering exceptional sharpness at 24mm. While the lens provides excellent value and versatility, performance is limited by soft corners at 12mm and a slow, variable f/6.3 aperture at the telephoto end, which restricts low-light performance.

Overview and Performance In this real-world review, Steve Huff defends the Olympus Micro 4/3 12-50mm kit lens, arguing it is a highly misunderstood and unfairly trashed lens that pairs perfectly with the weather-sealed Olympus OM-D E-M5 camera body. While critics often pan the lens for its slow variable aperture of f/3.5-6.3 and a perceived lack of micro-contrast, Huff finds the optical quality remarkably sharp for daily snapshots and vacation photos. He highlights its sleek, lightweight design and excellent internal mechanics, noting that the lens does not expand while zooming. Furthermore, its versatile 24-100mm equivalent focal range covers substantial ground, and a dedicated, easily engaged macro button sets the lens to a highly capable 43mm focal length at f/6 for close-up photography. Pros, Cons, and Value The lens boasts several distinct advantages, including robust weather-sealing, lightweight build quality, fast and silent autofocus for video, and a surprisingly effective one-click macro mode. However, it suffers from a slow aperture that drops to f/6.3 by the time it reaches 50mm, some distortion at the wide 12mm end, and a deficit in micro-contrast when...

The Olympus M.ZUIKO DIGITAL ED 12-50mm f/3.5-6.3 EZ is a tropicalized, motorized micro 4/3 kit zoom lens designed for videographers and photographers, offering an equivalent focal length of 24-100mm. Tested on cameras like the Panasonic GH2 and Olympus PEN EPL2, the lens earns a consumer-grade DxOMark score of 10, performing comparably to entry-level kit lenses. Its primary pros include quiet motorization with adjustable speeds for video zooming, a traditional zoom ring option, solid management of vignetting and distortion, and a lightweight, compact build. Furthermore, it yields satisfactory sharpness that peaks in the center at 12mm f/3.5 and becomes uniform across the frame at f/8. Conversely, the lens's most prominent con is its lack of brightness, making low-light shooting highly challenging when paired with a smaller micro 4/3 sensor. This slow aperture makes its $499 retail price hard to justify against alternatives like the Panasonic LUMIX G X VARIO PZ 14-42mm, which is $100 cheaper, brighter, more compact, and sharper. Additional weaknesses include visible chromatic aberrations heavily concentrated in the corners at the 12mm focal length. Ultimately, while it is a...

The Olympus 12-50mm f/3.5-6.3 is an electronic, fly-by-wire kit lens designed for Micro Four Thirds (m4/3) cameras, weighing a lightweight 7.4 ounces due to its extensive use of plastic. The reviewer emphasizes that this lens excels far more as a video tool than as a still photography lens. Its primary advantages include a silent, motorized zoom option that eliminates noise during filming, dust and splash-proof construction, and a fast, quiet "MSC" autofocus system. Additionally, it features a dedicated, lockable 43mm macro mode providing a useful 1:3 magnification ratio, alongside a programmable L.FN button for custom camera settings. However, the lens suffers from notable optical compromises, particularly at the 12mm wide-angle setting. The reviewer notes that sharpness never rivals prime lenses, with image quality degrading slightly when stopped down at 12mm. Still photographers will encounter heavy barrel distortion, severe vignetting, and highly visible chromatic aberration in the corners at the wide end—flaws that require extensive post-processing. Furthermore, the lens lacks optical stabilization, is prone to distracting flare when light hits the edge of the frame, and skips premium physical details like...

The Olympus M.Zuiko Digital ED 12-50mm f/3.5-6.3 EZ is a versatile, weather-sealed zoom lens suited for both stills and video, offering high center resolution, low distortion, and effective flare control. Despite these strengths, the review notes significant limitations, including edge softness, noticeable diffraction at narrow apertures (f/11–f/22), and moderate chromatic aberration at extreme focal lengths.

The Olympus M.ZUIKO 12-50mm f/3.5-6.3 EZ is the review's overall winner due to its superior feature set and versatility. Its primary strengths include unique weather sealing for a non-pro lens, an internal electronic zoom, a dedicated macro mode with a 1:3 reproduction scale, and a wider 12mm starting focal length. While it leads in sharpness at the 42mm telephoto end, its significant drawback is poor performance at the image borders when shooting at 14mm. Additionally, it is the slowest lens in the group, reaching a maximum aperture of only f/5.1 at 25mm and f/5.8 at 42mm. The Panasonic Lumix 14-45mm and 14-42mm (I) performed similarly, debunking the common perception that the older 14-45mm is vastly superior. The 14-45mm excels at 14mm sharpness but struggles at 25mm and 42mm, while both Panasonic models suffer from higher distortion and vignetting compared to their Olympus rivals. The Olympus M.ZUIKO 14-42mm (I) is ranked as the worst option, criticized for its noisy autofocus and rotating front element which hinders filter use. Though it is the fastest at 25mm (f/4.4), it consistently delivers the lowest...

The Olympus M.ZUIKO DIGITAL ED 12-50mm f3.5-6.3 EZ receives an overall DXOMARK score of 15 when evaluated on the Olympus OM-D E-M1 Mark II, peaking in performance at 12mm and f/3.5. The technical metrics highlight several strong pros for day-to-day use, including incredibly low distortion at 0.5% and minimal vignetting measured at just -0.6 EV. Its light transmission remains stable at 5.3 TStop, and it handles normal framing needs well by remaining compact and lightweight. However, the review uncovers significant optical cons that align with standard consumer kit lens limitations. Its sharpness score is quite low at only 5 P-Mpix, highlighting a softer rendering that drops further in quality toward the 50mm telephoto end. Additionally, it struggles with chromatic aberration, which registers at a noticeable 13 µm and is particularly evident as purple fringing in the corners at the wide 12mm setting. Ultimately, while its slow variable aperture of f/3.5-6.3 hinders low-light performance, it remains a highly versatile option for outdoor shooting and video thanks to its unique electronic power zoom mechanism.
