Panasonic LUMIX G Vario 7 14mm F 4 ASPH Análisis | 54 Datos comparados

The DPReview evaluation highlights the Panasonic Lumix G Vario 7-14mm F4 ASPH as a compact, lightweight, and high-performance lens offering excellent sharpness across the frame and near-silent autofocus. While producing impressive image quality and low flare, the lens is lauded for its ultra-wide 14-28mm equivalent field of view, making it a strong choice for Micro Four Thirds users, particularly when stopped down to f/5.6. However, the review cites a steep ~$1,000 price point and a bulbous front element that prohibits the use of standard screw-on filters, a significant drawback for landscape shooters. Additionally, While Panasonic bodies offer excellent automatic correction, users of older Olympus cameras may encounter notable color fringing due to a lack of native in-camera correction for this specific lens.

The Panasonic 7-14mm f/4 Lumix G Vario is a compact, lightweight ultra-wide-angle lens for Micro Four Thirds cameras, offering outstanding center sharpness and a 114-degree field of view. It features fast, silent internal autofocus and a constant f/4 aperture throughout the zoom range. Key cons include the inability to use standard screw-on filters due to the bulbous front element, a lack of weather sealing, and a high price point. It is also known to produce purple flare when used on Olympus camera bodies.

The Panasonic Lumix 7-14mm f4 review by Gordon Laing highlights this ultra-wide angle zoom lens as a highly portable and optically superb choice for Micro Four Thirds camera systems. Key strengths include its unbelievably compact and lightweight design (weighing just 300g), which delivers a versatile full-frame equivalent range of 14-28mm. Optically, it excels at providing exceptional corner-to-corner sharpness, minimal geometric distortion, and near-silent autofocus, while its constant f4 aperture keeps exposures uniform throughout the zoom range. A well-designed, built-in petal lens hood effectively shields the bulbous front glass element from flare and physical hazards, proving highly durable for long-term travel photography. However, the lens carries a relatively high price tag given its surprisingly ordinary plastic exterior, which mimics the design of a basic kit lens rather than a premium model. The most notable physical flaws are the complete lack of weather-sealing and the inability to mount traditional front or rear filters due to the protruding front glass. Optically, users must watch out for image degradation caused by diffraction at apertures smaller than f8. Furthermore, a prominent compatibility flaw exists where...

This review evaluates the Panasonic 7-14mm f/4 ASPH LUMIX G VARIO lens, an ultra-wide-angle zoom lens designed for Micro Four Thirds cameras. Tested on the Panasonic GX7, the lens stands out for its remarkably compact build (8.3 cm long) and lightweight design (300 grams), making it highly portable compared to APS-C or full-frame equivalents. The reviewer praises its exceptional optical performance, highlighting its maximum center sharpness even at full aperture, incredibly low distortion (aided by in-camera corrections), and virtually non-existent chromatic aberration. Autofocus is described as fast, accurate, and quiet, making the lens a highly versatile and recommended choice for landscape, architectural, and street photography. However, the lens does come with notable drawbacks, including a high price tag and visible vignetting of just over one stop at the maximum f/4 aperture across all focal lengths. Due to its convex front lens element and a fixed built-in lens hood, users cannot attach standard protection or UV filters. This specific design also makes the lens prone to ghosting and flare when bright sunlight hits the glass at an acute angle, and susceptible...

The Panasonic Lumix 7-14mm f/4 lens is a ultra-wide-angle tool designed for Micro Four Thirds systems, offering an angle of view comparable to a 14-24mm lens on a full-frame camera. In his review, Boon Vong highlights the lens's specialized utility for event and wedding photography, specifically for capturing edge-to-edge room interiors and architecture where backing up is not an option. Its standout features (pros) include an incredibly compact size that easily fits into a small side bag, and a wide depth of field that makes manual focusing highly forgiving. Furthermore, when paired with the in-body image stabilization of cameras like the Olympus E-M1 or E-M5, photographers can shoot at slow shutter speeds like 1/8 of a second to keep ISO low. He also notes it pairs well with the Blackmagic Pocket Cinema Camera for less-distorted environmental shots. However, the lens comes with several notable optical and performance drawbacks (cons). Vong notes that autofocusing in AF-S mode performs poorly, forcing him to rely on AF-C or manual focus to get reliable results. The lens is also highly prone to keystoning and...

The Panasonic 7-14mm f/4 ASPH LUMIX G VARIO lens delivers impressive optical performance in a compact, 300-gram plastic body designed for the micro-four-thirds system. It provides a 14-28mm effective field of view with an ultra-fast, silent autofocus that clears its focus range in under a second. Its strongest pros include remarkable image sharpness, particularly between 7-12mm where the center is tack-sharp at f/4, and optimal consistency across the frame at f/5.6. Furthermore, distortion is exceptionally well-controlled, showing minimal barrel distortion at 7mm, slight pincushioning at 14mm, and virtually flawless results in between. However, the lens has notable design limitations and optical cons. The primary drawback is strong chromatic aberration and purple fringing in high-contrast corner areas, especially between 7-11mm. Structurally, the integrated, petal-shaped lens hood and large protruding front element completely prevent the use of standard screw-mounted filters. It is also poorly suited for macro photography, offering a meager 0.15x magnification despite its 25cm close-focusing distance. Finally, severe diffraction compromises image quality when fully stopped down to f/22.

The Panasonic Lumix G Vario 7-14mm F4 ASPH achieves an overall DXOMARK Score of 19 when tested on the Olympus OM-D E-M1 Mark II, performing at its absolute best at a focal length of 7mm and an aperture of f/4. The review highlights prominent pros including a strong sharpness score of 12 P-Mpix, which delivers excellent detail retention for an ultra-wide zoom. Additionally, the lens controls geometric distortion incredibly well for its wide field of view, keeping it to a minimal 0.9 %. Conversely, the evaluation reveals specific cons regarding light loss, vignette, and color fringing. It suffers from a light transmission drop measured at 4.4 TStop, indicating a reduction in light efficiency compared to its f/4 physical aperture. Furthermore, a significant corner shading effect is noted with a vignetting score of -1.6 EV, alongside noticeable chromatic aberration measuring at 19 µm, which could require post-processing corrections to clean up color artifacts in high-contrast edge details.
