Panasonic Leica DG Vario Summilux 10 25mm F 1 7 ASPH Análisis | 54 Datos comparados

The Leica DG 10-25mm f1.7 ASPH is a unique, high-end standard zoom lens designed by Leica and manufactured by Panasonic for the Micro Four Thirds system. Delivering a highly versatile 20-50mm equivalent focal range, it is specifically optimized for videographers and low-light photographers due to its incredibly bright, constant f1.7 focal ratio. Key strengths include its exceptional optical and build quality, a close 28cm minimum focusing distance for detailed close-ups, and a dust and splash-proof barrel design. Video-centric features highly praise the smooth, click-less aperture ring (compatible with most Lumix G bodies) and a pull-back focus clutch ring that allows for predictable linear manual focusing adjustments. However, the review highlights several distinct drawbacks, most notably its very high price tag of around $1,800 and its lack of built-in optical image stabilization. At 690g with a massive 88mm diameter barrel, it is physically gargantuan compared to other Micro Four Thirds options and balances best only on larger camera bodies like the Panasonic GH or Olympus EM1 series. Testing also revealed noticeable field curvature compared to alternative glass. Ultimately, while wide-angle stills...

The Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 ASPH lens offers exceptional optical quality for Micro Four Thirds, delivering outstanding central sharpness, low distortion, and well-controlled chromatic aberration, along with a smooth bokeh and fast autofocus. Its premium, weather-sealed construction and click-free aperture control make it a versatile, prime-replacing option for both photographers and videographers. Key drawbacks noted in the review include a petal lens hood with a release catch that easily disengages in camera bags and somewhat vague, ambivalent descriptions of the lens's water-ingress protection. While flare is possible in harsh, direct lighting, the lens provides high-end performance, though at a premium cost and size.

David Thorpe’s review on ePHOTOzine highlights the Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 lens as a "faultless" prime-lens replacement offering superb sharpness, constant f/1.7 aperture, and a clickless aperture ring ideal for video, along with fast autofocus. While praised for its stellar optical performance, the lens is notably large and heavy, expensive, lacks internal image stabilization, and features a loose lens hood.

The Panasonic Leica DG Vario-Summilux 10-25mm F1.7 ASPH is a premium Micro Four Thirds lens featuring a unique constant F1.7 zoom aperture covering a 20-50mm equivalent range, effectively replacing multiple prime lenses. Optimized for video, the, rugged, weather-sealed, 690-gram lens includes a clickless aperture ring and linear focus clutch, though it lacks built-in optical image stabilization. Key compromises noted in the hands-on review include its bulky, heavy design which may unbalance smaller bodies, and a high, professional-tier price point. Despite its size, the lens is lauded for exceptional build and optical versatility, making it a powerful tool for serious videographers and photographers looking for top-tier image quality in a single, fast zoom package.

The Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 ASPH is a highly unique wide-angle zoom lens designed for Micro Four Thirds system cameras, offering an equivalent 35mm focal range of 20mm to 50mm. It stands out as the brightest zoom lens in the world with a fixed f/1.7 aperture, making it an excellent choice for low-light photography and creating a three-dimensional bokeh effect that isolates subjects from the background. The review highlights that the lens is heavily optimized for videographers due to its clickless, stepless aperture ring, a linear manual focus clutch with physical stops, and a barycentric design that completely eliminates focus breathing. In terms of image quality, it scores an overall 80, delivering exceptionally high center sharpness at full aperture and peak performance across the frame when stopped down to f/4 or f/5.6. The lens boasts several significant pros, including its record-breaking brightness, versatile range, superb optical performance, and robust, dust- and splashwater-tight construction. Additionally, vignetting remains remarkably low in RAW files, and flare is minimal even when shooting directly into backlighting. However, these premium features come with distinct...

The LensTip review evaluates the Panasonic Leica DG Vario-Summilux 10-25 mm f/1.7 ASPH as a premium, highly anticipated standard zoom lens for Micro Four Thirds systems that merges an unusual wide-to-standard focal range with an incredibly fast f/1.7 constant aperture. Optically, the reviewer praises its outstanding image quality in the frame centre and excellent sharpness at the edges, noting it stands toe-to-toe with high-end fixed focal length prime lenses. Additional mechanical and structural advantages highlighted in the review include a solid casing with top-of-the-range build quality, a highly efficient, fast, and silent autofocus motor, and an lack of issues stemming from spherical aberration. The lens also scores highly for its sensible correction of lateral chromatic aberration, moderate coma, and solid performance when shooting against bright light. However, the review points out several optical and physical limitations that users must accept, particularly regarding uncorrected RAW files. The most prominent optical flaw is the huge barrel distortion in RAW files which reaches a massive −5.98% at the 10 mm wide-angle end and remains noticeably high at 12 mm (−3.89%) and 14 mm...

The ePHOTOzine review highlights the Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 ASPH as a versatile, bright wide-to-standard zoom for Micro Four Thirds, offering outstanding central sharpness and excellent performance from f/1.7 to f/8. Key strengths include extremely low distortion, controlled chromatic aberration, fast autofocus, and a click-free aperture ring ideal for video, though it is notably large for the system. Drawbacks center on design, specifically a protruding lens hood release catch that is easily pressed by accident, potentially causing the hood to detach. Additionally, the review cites vague dust/splash resistance claims, a bulky design with a 77mm filter thread, and a slight susceptibility to flare in direct light.

The Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 is a versatile Micro Four Thirds zoom lens offering exceptional sharpness, beautiful bokeh, and a robust weather-sealed construction with a constant f/1.7 aperture. It caters to videographers and hybrid shooters with a de-clicked aperture ring and manual focus clutch, performing best on ergonomic bodies like the Panasonic G9. Conversely, the lens is notably large and heavy, contradicting the compact nature of MFT systems, and it lacks internal optical image stabilization. Additionally, the review notes a flawed, easily detached lens hood design and a high price point.
