I think there is a case for the FF equivalent to the DA 15 mm f 4.0 limited. I have the 15-30 mm lens and it is really good lens (I use it for home interiors and architecture) but something like a 21 mm f 4.0 would help to make the K-1 more practical travel camera. 21 mm for me makes a dramatic landscape perspective whilst the f 4.0 would enable significant compactness.
I have the 24 mm F 3.5 which is a nice lens but it does show its age in the K-1.
The new 35mm f2.0 seems like a nice makeover to an old lens that is obviously still in demand.
Ricoh's slow release schedule allows time for development of stellar lenses and it also gives us time to save up for our next purchase!
