Olympus M.Zuiko Digital ED 12 100mm F4 0 IS Pro Review | 54 Data compared

The DPReview field review identifies the Olympus M.Zuiko 12-100mm F4 IS Pro as a high-performance "all-in-one" zoom, praised for its exceptional sharpness across a 24-200mm equivalent range and a 5-axis Sync IS system providing up to 8 stops of compensation. The lens features professional, rugged sealing and a, versatile 1.5 cm close-focusing distance at the wide end. While offering premium versatility, the 561-gram lens can feel unbalanced on smaller bodies and has a constant F4 aperture that limits, lower-light performance compared to faster lenses. Minor corner softness at 12mm is also noted as a tradeoff for its extreme zoom range.

The Imaging Resource review highlights the Olympus 12-100mm f/4 IS Pro as a versatile travel lens, praising its outstanding optical sharpness across the entire zoom range and highly effective 5-Axis Sync Image Stabilization. Key strengths include a robust, weather-sealed design, a close minimum focusing distance, and a useful manual focus clutch. Considerations include a high price point and a heavier, larger form factor compared to other Micro Four Thirds lenses. Additionally, the constant f/4 aperture offers limited low-light performance and shallow depth-of-field capabilities compared to f/2.8 alternatives.

The Olympus M.Zuiko 12-100mm f/4 IS PRO is a highly versatile, professional-grade travel zoom lens for Micro Four Thirds cameras that delivers impressive image quality across its extensive 24-200mm (full-frame equivalent) focal range. A standout feature is its class-leading image stabilization system, which achieves up to 6.5 f-stops of efficiency when paired with compatible Olympus bodies using "Sync IS". The lens boasts an exceptional, tightly assembled, and weather-sealed metal body with smooth control rings and a fast, silent MSC autofocus motor. Optically, it defies typical long-range zoom limitations by maintaining a constant f/4 aperture and offering superb center sharpness that peaks at f/4 and f/5.6, along with very low chromatic aberrations and a smooth background bokeh. Despite its high praise, the lens does come with notable compromises, primarily its hefty price tag of around $1,300/EUR and a design that is larger and heavier than typical Micro Four Thirds options. In terms of optical performance, it heavily relies on digital auto-correction to mask flaws; uncorrected RAW files exhibit a massive 6.9% barrel distortion and heavy vignetting peaking at 1.8EV at the...

The M.Zuiko PRO 12-100 mm f/4 IS zoom lens serves as a highly versatile, robust "one lens" solution tailored specifically for travel, everyday use, and documentary photography. The reviewer heavily praises its exceptional optical sharpness, accurate color rendition, and fast autofocusing capabilities even under demanding conditions. A standout feature is its Sync-IS capability when paired with compatible Olympus/OM System bodies, allowing for reliable, sharp handheld shooting at shutter speeds as slow as 1/2 to 4 seconds while maintaining a low base ISO of 200. Additionally, its weather sealing proves flawless against harsh elements like rain, wind, and snow, and the inclusion of a physical focus clutch adds to its premium handling. However, the lens presents a few notable drawbacks depending on user priorities. Its constant f/4 maximum aperture is considered too slow for low-light client video work, which restricts dramatic background isolation unless specific attention is paid to subject-to-background distance. Compared to more compact Micro 4/3 alternatives—such as the dual-lens PRO 12-45mm and 40-150mm setup or the 14-150mm f/4-5.6 II—the 12-100mm is physically bulky and heavy. Lastly, it can feel...

The LensTip review of the Olympus M.Zuiko Digital ED 12-100 mm f/4 IS PRO highly praises the lens for exploiting the full potential of the Micro Four Thirds sensor to deliver unprecedented image sharpness for an 8.3x high-magnification zoom lens. Testing on RAW files revealed that the lens achieves "revelational" sharpness at its wide 12mm end—nearly reaching the record values of premium prime lenses—and maintains excellent resolution across the entire frame and zoom range even at the maximum f/4 relative aperture. Additional prominent strengths include a robust, weather-sealed casing, a sensational optical image stabilization unit, and a silent, exceptionally fast autofocus system. Optically, it also excels by showcasing low coma, slight astigmatism, minimal spherical aberration, and commendable resistance to ghosting and flares. LensTip.com The primary drawback identified in the review is the huge geometric distortion present in uncorrected RAW files, which spikes to a massive -6.90% barrel distortion at 12mm and.84% pincushion distortion at the telephoto end. This indicates that the lens designers completely relied on digital camera software to correct geometry rather than solving it optically. Beyond this main...
