Panasonic announced several new converter lenses for their 14mm f/2.8 and X 14-42mm lenses:
DMW-GWC1 Wide Conversion Lens – converts 14mm to 11mm for use on 14mm f/2.5 and the LUMIX G X VARIO PZ 14-42mm
DMW-GTC1 Tele Conversion Lens – 2x zoom – converts 42mm to 84mm for use on the LUMIX G X VARIO PZ 14-42mm
DMW-GMC1 Macro Conversion Lens – for use on 14mm f/2.5 and the LUMIX G X VARIO PZ 14-42mm
DMW-GFC1 Fisheye Conversion Lens – for use on 14mm f/2.5 and the LUMIX G X VARIO PZ 14-42mm
Sigma have announced two new lenses for Micro Four Thirds and Sony NEX mirrorless systems:
- Sigma 19mm f/2.8 EX DN aspherical which will give 38mm FOV on MFT and 28.5mm FOV on NEX
- Sigma 30mm f/2.8 EX DN aspherical which will give 60mm FOV on MFT and 45mm FOV on NEX
Neither of these are particularly wide aperture but presumably Sigma is targetting high optical image quality rather than pancake size or fast aperture.
I am not sure how these will go in a market of 17mm f/2.8 pancake, 20mm f/1.7 pancake, and 25mm f/1.4 high image quality Micro Four Thirds lenses which are already available. Perhaps they are largely targetting the relatively weak Sony NEX lens line up.
