Sharpness and Contrast Way
Up in the Excellent Scale
The Panasonic 25mm f/1.4 Leica D Summilux
Lens a bright standard lens, designed by Leica solely for DSLR cameras, and meets the Four Thirds Standard allowing the lens to be interchangeable with other cameras that employ the same format.
Manufactured by Panasonic in Japan to Leica specifications, with a typical internet price of $1,100 is the number two lens Panasonic introduced for the
Lumix DMC-L10 DSLR. In the Four Thirds system its a 50mm equivalent lens that plugs a hole in the Olympus/Panasonic lens line up, and it's appropriate that Panasonic started with a most basic lens, a fast "normal" prime.
Analogous to the similar Sigma 30mm f/1.4 ($489, typical internet price), the Panasonic is a little lengthier and weighs more than you would expect. Four Thirds lenses need extra-big glass elements (in relationship to 35mm full frame lenses) necessary for greater light collecting required to broadcast rays perpendicularly onto the sensor plane or else, unacceptable edge falloff occurs.
The Panasonic 25mm enjoys a polycarbonate enclosure that feels more like metal. It has smooth-operating manual-focusing ring that's fine ribbed plus rubber-covered is continuously turning, featuring no near or far-focus stops.
AF operation is both fast and stealth when mounted on the DMC-L10. In Leica's tradition, the aperture locking ring is situated at the farthest end of the barrel. You'll be pleasantly surprised to discover this large lens casts no shadow (even with the flower petal lens hood installed) when employed with the built-in flash of the L1.
Just as you've come to expect of Leica, SQF information shows sharpness and contrast way up in the Excellent scale. With this range of sharpness, fast speed, and control of distortion, this lens is grabbed up by Olympus and Panasonic photographers alike. With its lofty Leica-type pricing, however, those photographers who can put up with some distortion compromise may decide to save $589 by going with the 30mm Sigma.
With a super-bright maximum f/1.4 aperture plus a focal length coming closest to that of the human eye (50mm in 35mm film format
equivalent), this is the perfect all purpose lens for every shooting environment.
An f/1.4 lens is not usually as efficient as the same manufacture's f/1.8 or f/2
lenses, even when both are stopped down to f/5.6. the lens with the wider
aperture is heaver and more expensive, so don't choose it as your standard
unless you are planning a great deal of photography poor light conditions.
There' plenty of reasons for using a wide aperture, but avoid buying a lens with
an aperture wider than you need.
