This 3D lens H-FT012E works great on a G2 after a firmware update. For the G1, GF1 and GH1 and Olympus the MFT cameras no update is available. Optical coherent sees the from of a DMC-GF3 the lens, on a G2 it acts verlohren something. Of course, make 3D photos with the appropriate display hardware really mind. Since the camera in addition to MPO photo still records a JPEG, the photos can also be quite normal view (without 3D effect). Hardware: The 45g light lens comes with known bags and covers. The shape of the lens cover no installation of filters or other lens attachments is possible. In 3D photos a high depth of field is essential. Therefore, Panasonic has built a relatively small fixed orifice 12. About the focusing one need do no Gadanken because this possibility does not exist (and because of the high depth of field also not necessary). Of course, the small aperture limits the fields of application: Outdoor photos without a tripod are possible only in bright light because the aperture priority pretending pretty slow shutter speeds. In sports photography is unthinkable! Indoor can not be waived on a tripod. For me, the field of use limited to photos with tripod, preferably still life. Definitely not a party and Snapshot lens.
