Fantastic Pancake Lens6/14/2013
Great optics. Sturdy design.
I originally bought the Panasonic Lumix GF1 with the 14-45mm kit lens, and then bought this 20mm pancake. The pancake turns the GF1 into a really compact set, that I enjoy taking together anywhere. I keep the 20mm lens in the camera most of the times, and only when I know I'll need some telephoto I replace it by the 14-45mm lens. I owned previously only point-and-shoot and superzooms, so I wanted to try some DSLR, but I was afraid I wouldn't take together because of the bulk. With the GF1 + this pancake lens I have a small camera that I don't mind carrying and that takes DSLR-quality photos.
Expensive but very good5/10/2012
There's plenty already said about this lens. I'm using this on E-PL1. It works great although the focus could be faster. This combo is pretty affordable for compact ILC for use in low light situation. I notice a little vignette and distortion as expected since E-PL1 does not do automatic lens correction like other Lumix camera. However, this is easy fixed in post-processing.
Lumix 20mm F1.7 Lens used on Olympus EPL11/19/2011
I bought this lens to use with my new Olympus EPL1 camera because the Olympus camera has better reviews and is actually cheaper than the Lumix camera but this fixed focal length lens is overall better than what Olympus has in similar focal lengths in terms of aperture. It is really nice that the mounts are the same (no adapter is required) and all the autofocus and aperture setting occurs seamlessly. Gives very nice low light pictures.
