According to Amateur Photographer, Ricoh will introduce two new GXR lenses in 2010:
Due for sale in Summer 2010 will be the P10 28-300mm f/3.5-5.6 VC unit that will include a compact sensor with a resolution of 10 million pixels. The CMOS sensor will be back-illuminated, as with the unit used in the new CX3 camera, which will reduce the impact of noise in low light situations. A 28mm lens on an APS-C sensor is 42mm-e, my ideal focal length. If it performs as well as the 33mm macro, I'll be joining the GXR team.
A GR Lens A12 28mm f/2.5 is due for launch in winter 2010 and will be fitted with a 12 million pixel APS-C sized CMOS sensor. Ricoh says this lens will have a manual focus ring as well as an AF system, and will be powered by Ricoh's GR Engine III.
Uh-oh! It occurred to me that, because it's an APS-C sensor, this should have gone in the "Other Cameras" forum. But the other lens unit has a small sensor. And now I've realized that the 28mm lens unit might be 28mm-e. In which case, I won't be joining the GXR team.
What a shemozzle! My apologies to all.
