The Panasonic Lumix G 20mm F1.7 ASPH was declared lately as the organic affiliate to the lightweight Lumix DMC-GF1 Little Four Thirds electronic dslr electronic camera, together with a Leica-branded 45mm F2.8 Macro (the electronic dslr electronic camera is also available with a 14-45mm kit zoom). The H-H020, as Panasonic incredibly wants to contact it, is a huge highest possible possible aperture 'normal' primary in a very lightweight 'pancake'-type program. It creates up a quit and a 50 % more mild than Olympus's M. Zuiko Digital 17mm F2.8 hot sweet (which is only partially smaller), and is therefore sure to be of attention to E-P1 entrepreneurs who want to capture in low mild using a relationships well-matched to that online digital camera's measurement.

The F1.7 aperture is quick for a hot sweet relationships, and to accomplish this Panasonic has handled to press a 7 element, 5 team style into that lightweight gun gun gun barrel, such as two aspheric components to help decrease disruptions and chromatic aberration. There's a 7-bladed aperture program, using rounded knives developed to provide an eye-catching, sleek impact to out of concentrate features. Rounding off the specifications is a tiniest concentrate wide range of just 20cm. However it's important to note, that contrary to many of Pansonic's relationships, this doesn't have built-in visual picture stabilisation.

The 40mm-equivalent position of viewpoint may originally appear uncommon, but this is actually a 'perfect normal' relationships, with a primary duration just like the indication angled. What this implies is that it provides pictures in a very quite quite fairly neutral style, completely without any the 'perspective distortion' associated with wideangle or telephoto relationships. While this primary duration was generally less typical than the well-known 50mm primary on Drawbacks cameras, it still packed an reasonable market as the conventional relationships for a wide range of high-quality compacts, such as the Leica / Minolta CL. Indeed with that 45mm F2.8 macro and an future 14mm F2.8, Panasonic seems to be placement the GF1 as the religious heir to companies the CL and the Contax G sequence - as a top amazing realistic electronic dslr electronic camera program for serious electronic cameras lovers. Let's see if the pancake's picture amazing can stay up to such considerable objectives.
