Who really knows what the reasons actually are:
- Yen/Dollar trade - a year ago the relationship was quite different.
- Inventory adjustment - What do they have in their warehouses vs on the dealer's shelf.
- Production allocation - The production of various lens vs what has been selling of late.
- The whole mirrorless - dSLR question and the relationship it has on what lenses are selling?
- What is selling vs what is not?
- What is generating the most profit?
- What they want to encourage the selling of?
- New lens announcements vs current inventory - what is replacing what perhaps?
You can only make some educated guesses from reading the tea leaves of the financial statements.... Then there is Photokia in a few weeks.
