Best Camera lens Panasonic Leica DG Summilux 25mm


The Panasonic Leica DG Summilux 25mm f/1.4 ASPH is a standard lens for the Micro Four Thirds system. Presenting a 35mm camera corresponding focal length of 50mm, the Panasonic 25mm lens is composed of 9 elements arranged in 7 groups, including 2 spherical elements and 1 ultra-high-refractive-index lens element. It features a particular Nano Surface Coating to minimize ghosting and sparkle, and an iris diaphragm with seven curved aperture blades. It was announced in June 2011, the 25mm f1.4 is the second Leica lens from Panasonic for the Micro Four Thirds system as its predecessor 45mm f2.8 macro lens, that means Leica give a specific design to the optics and Panasonic takes the process of manufacturing under authorization in Japan.

Grippingly it is the first Micro Four Thirds lens to give so-called ordinary coverage, corresponding to 50mm on a full-frame body, and since then there's only been one substitute sharing the same focal length: the Voigtlander 25mm f0.95 which improves it on focal ratio, but is larger and manual focus only. So more affordable and for general use only, here it is, Panasonic's own 20mm f1.7 lens with a 40mm corresponding field of view. The Panasonic 20mm f1.7 is of course the next competitor to the 25mm f1.4.


Review of Panasonic Leica DG Summilux 25mm f/1.4:

The 25mm f1.4 is the second Leica-branded lens from Panasonic for the Micro Four Thirds system. There's more than a transitory similarity with the former 45mm f2.8 macro. At first look, the lenses look almost the same, sharing a balanced barrel, smooth and silky manual focusing ring; 46mm filter thread and elegant black coating with calligraphy in Leica's squared-off font.

63mm in diameter and 55mm in length, the 25mm f1.4 isthe similar width but a bit shorter than its predecessor and the two switches on the side are absent; there's no need for a focus limiter on a lens like this, and unhappily no image stabilization to turn on and off either, so if you're rising it on a Panasonic body, it'll become a non-stabilized arrangement. It's visibly a lot larger than the different lenses accessible for the Micro Four Thirds format and therefore looks more natural on the mini-DSLR bodies.



Like the 45mm f2.8 before it, the lens is conquered by a wide manual focusing ring that's perfectly silky smooth in operation. It feels like as we are using one of Canon or Nikon's top-end expert lenses, and after a few moments pushing the ring back and forth it's hard to return to the stiffer and scratchier manual focusing rings of cheaper models like the 20mm f1.7. It’s mainly satisfying to turn when pulling-focus on movies.
