Our friend Valentin Sama tested the Panasonic 14mm f/2.5 lens at DSLRmagazine (Click here to read the google english translation).
No flare, good contrast, good color ad fast AF (on a Panasonic camera). The resolution wide open is good in the center and sufficient o the border (that’s not really exceptional for a prime lens, but hey it’s an ultracompact lens!). Distortions and Lateral CAs are well controlled. The conclusion do math the verdict from Photozone (Click here) that tested the lens a couple of months ago.
Pancakes are one of the reason why one should join Micro Four Thirds. And the Panasonic 14mm f/2.5 lens is the smallest of all MFT lenses. Would love to see some more of them!
