保有Pentax 21％股票的大股東 SPARX Asset Management ，
向Pentax的經營層建議，Pentax自數位相機生產撤退。
因為數位相機產品周期太短，對相機(光學?)製造廠來說並不適合。

Abe:
Let me discuss Pentax, of which we hold 21 percent.
Pentax is an optical technology company that is known for making single-reflex lenses.
Japanese camera makers have their roots in lens making and optical technology.
Leveraging its technological strength, Pentax has diversified into endoscopy, an area that Japanese companies monopolize.
The neat thing about the endoscope business is that once you become a supplier, you have a lock on demand for parts replacement the same way copy machine makers benefit from continuing demand for, say, toner.
The mistake that Pentax and other camera manufacturers made was in digital cameras, which as a business are not like cameras but more like home electronics, with short product cycles.
It's not an efficient business for camera manufacturers to be in. We have been in talks with the Pentax management and have been suggesting that they exit from digital camera manufacturing.
This also represents a new way of communicating and relating with the management as shareholders.
There are lots of Japanese companies that can improve through an arrangement whereby shareholders, management and employees share in the benefits.
