Panasonic Leica DG Vario Elmarit 8 18mm F 2 8 4 0 ASPH Análisis | 54 Datos comparados

The ePhotoZine review awards the Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH lens a highly favorable rating, praising its outstanding sharpness, excellent control over distortion, and robust, weather-sealed construction. This professional-grade, wide-angle zoom for Micro Four Thirds cameras further features a fast, near-silent autofocus system suitable for both stills and video. Conversely, the review highlights the variable f/2.8-4 aperture as a limitation, which reduces light-gathering capabilities at the 18mm end compared to constant-aperture alternatives. Additionally, the lens lacks built-in optical image stabilization, meaning it relies on the user's camera body for stabilization.

The Panasonic Leica 8-18mm f/2.8-4.0 is a highly versatile, weather-sealed wide-angle zoom lens designed for Micro Four Thirds cameras, offering a 35mm equivalent focal range of 16-36mm. The reviewer notes that its optical sharpness is excellent across the frame, peaking between f/4 and f/5.6, while aberrations, distortion, and vignetting are remarkably well controlled. Key advantages include a solid, mostly metal build quality, a fast and silent autofocus system, and a 23cm minimum focusing distance that allows for close-up work with decent bokeh. Crucially, it features a 67mm filter thread, giving it a massive edge over the bulkier Olympus 7-14mm PRO by removing the need for a bulky, third-party filter adapter. On the downside, the lens lacks built-in optical stabilization and does not feature a constant f/2.8 aperture, which drops to f/4 at the telephoto end and limits its performance in low-light environments. Additionally, it is prone to ghost flares when shooting directly into light sources, and its size makes it a better fit for mid-to-large camera bodies rather than compact models. The lens is also quite expensive, though the reviewer...

The review by Tony Ventouris on Unlocking Olympus highly praises the Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 Aspherical Lens, framing it as an exceptional wide-angle zoom option that gets nearly everything right for Micro Four Thirds photographers. The primary pros highlighted in the review focus on its stellar optical performance and versatile design. It delivers excellent sharpness throughout the zoom range and features a robust, weather-sealed metallic build quality that handles challenging environments with ease. Additionally, the lens utilizes an internal zoom mechanism, meaning its physical length stays constant, which greatly improves balance and handling on compact camera bodies. Unlike many ultra-wide lenses with bulbous front elements, it also accepts standard 67mm screw-in filters, which is a massive advantage for landscape photographers who rely on circular polarizers and ND filters. On the downside, the review notes a couple of specific cons inherent to its design and specifications. A major compromise is its variable aperture range of f/2.8 to f/4, meaning the lens loses light transmission as you zoom in toward the 18mm focal length. This makes it less ideal for...

The Finding Range review highly praises the Panasonic Leica Vario-Elmarit 8-18mm f2.8-4 ASPH lens for its premium metal construction, versatility, and exceptional performance on Micro Four Thirds cameras. Priced at approximately $1,100, the author considers it a "must-buy" due to its sturdy, weather-sealed build (dust, splash, and freeze-proof down to -10ºC) and its surprisingly lightweight profile (315 g), which balances excellently even on compact bodies like the Olympus Pen-F. Additional prominent pros include a highly secure, easy-to-use locking lens hood and blazing fast, highly accurate autofocus. The 16-36mm equivalent focal range is lauded for being more practical on the long end than competitors like the Olympus 7-14mm f2.8. Optically, the lens delivers superb image quality characterized by rich color rendering, organic contrast, and razor-sharp detail extraction across the entire aperture range. Minor vignetting at f2.8 virtually disappears by f4, and a smooth bokeh can be achieved when shooting close-up subjects. The singular, notable con highlighted by the reviewer is that the lens flares and ghosts more than expected in certain lighting conditions, despite featuring a Nano Surface Coating. However, this...

The Panasonic Leica DG 8-18mm f/2.8-4 is a highly versatile, super-wide-angle zoom lens designed for Micro Four Thirds cameras, offering a 16-36mm equivalent field of view in full-frame terms. A key feature that sets this lens apart from typical ultra-wide zooms is its standard, non-convex front element, allowing photographers to easily use 67mm screw-in filters without specialized adapters. Weighing just over 3 ounces and measuring 9 cm long, it provides an exceptionally portable design that is both dust- and splashproof, as well as freeze-resistant. Autofocus performance is exceptionally fast and silent, clocking in at 125 milliseconds on a Panasonic GH5 due to an internal focusing system that moves a small internal element. Additionally, the lens achieves a high overall score of 75, backed by an intricate optical design of 15 elements in 10 groups, which relies on in-camera corrections to eliminate lateral chromatic aberration and distortion. The lens boasts several distinct advantages alongside a few minor trade-offs. On the positive side, its primary pros include fantastic, even sharpness across the entire image field, a highly durable and weather-sealed build, an...

The Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH is a beautifully made ultra-wide zoom lens for Micro Four Thirds cameras that delivers very sharp image centers across its "16-36mm" equivalent focal range. Its premium build features a dust-, splash-, and freeze-proof metal outer shell with smooth mechanical rings and a constant physical length during operation. It provides fast, silent autofocusing and includes a front filter thread, making it a highly practical alternative to competitors with bulbous front elements. When image auto-correction is active, real-life chromatic aberrations, distortions, and vignetting remain very low, resulting in good to very good performance at the image borders. However, the lens relies heavily on digital correction to mask its native flaws. Without software assistance, it suffers from an extreme 6.6% barrel distortion and noticeable 1.6EV light falloff at the 8mm wide end, which subsequently stretches and reduces corner sharpness. Reviewers also noted visible field curvature in the mid-range that introduces corner softness, alongside a lack of built-in optical image stabilization. While the centering quality of the tested sample was only decent rather than great, and minor...

The Panasonic Leica DG Vario-Elmarit 8-18 mm f/2.8-4 ASPH. review on LensTip highlights it as an excellent ultra-wide-angle zoom lens for the Micro Four Thirds system. Its main advantages include outstanding image sharpness in the frame centre across all focal lengths, paired with a robust, metal, weather-sealed casing. The lens is physically compact, lightweight, and features a standard 67 mm filter thread, preventing users from needing oversized, expensive filters. Optically, it excels at managing internal aberrations, offering virtually imperceptible longitudinal chromatic aberration, negligible spherical aberration, properly corrected coma, and lower vignetting compared to its competitors. Furthermore, it boasts an ultra-fast, silent, and highly efficient autofocus drive system. On the downside, LensTip notes that the lens experiences a noticeable drop in image quality on the edges of the frame, particularly when shooting at longer focal lengths. In terms of RAW files, it suffers from a huge barrel distortion level reaching as much as -6.59% at the 8mm focal length, which requires digital correction and subsequent image cropping. The optics can also struggle when shooting directly against bright light, occasionally producing distinct...
