Introduction | 2007 |
The Panasonic Leica D Summilux Asph 25mm F1.4 is an interchangeable camera lens announced by Panasonic on March 7, 2007.
Design
[edit]The lens uses 10 elements in 9 groups, arranged as a double Gauss type, with one aspherical, three extra-low dispersion (ED), and one super ED element. It was announced in March 2007, with availability starting that April.[1]
Reception
[edit]As reviewed in 2010, the lens exhibited little distortion and offered close to maximum resolution wide-open, improving slightly at f/2.[2] Resolution on the frame's edge was weaker, though, due to chromatic aberration and visible coma at maximum aperture.[3]
