Originally posted by Winder It is considerably easier to produce a high quality prime than it is to produce a zoom like the D-FA* 70-200mm. I think we see the 50mm late this year. Ricoh does seem to be painfully slow. The report says that the 50mm on display didn't even have glass in it, so they probably don't even have a working unit in testing yet. Or maybe Ricoh cares nothing about marketing.
I would not read much into the empty lens shell at CP+. To a large extent, the prototyping of the optics and the prototyping of the case can be parallel activities. Ricoh almost certainly has some butt-ugly brassboard prototypes of the optics lurking the R&D labs but those are not suitable for show.
Older primes may have been simple, but newer, high-performance primes are more like zooms in having internal focus and floating elements (i.e., more than one moving internal subassembly just like a zoom). Both the Otus 55/1.4 and Sigma 50/1.4 have a dozen or more elements (nearly twice the number of the old FA 50/1.4).
What's interesting is that RIcoh also makes copiers which, like high-end cameras are in a declining industry. But that does not mean a company cannot thrive. They just have to be careful.
The typical technology growth industry strategy of grabbing marketshare at any cost is very popular for smartphones and other fast-paced consumer electronics. But it is utterly wrong for mature or declining industries -- it's a recipe for bankruptcy. I think Ricoh knows this and are investing more modestly in R&D to create viable products at a sustainable pace. I tend to believe kenspo's assertions that Pentax has exciting things going on but also suspect that it's going to be a slow stream of new products rather than a blast that releases brand-new portfolios of products all at once.
