Originally posted by Kunzite Are you sure those numbers are all about digital cameras? I know what's written in those financial reports, I've read them myself (that brief footnote) - but Other also includes leasing and logistics, which appears to be very Japanese-centric businesses.
Assuming an average value of 44,000 Yen for a body and 22,500 Yen for a lens and assuming they would sell on average 1.5 lenses for a body (I know, lots of assumptions), 75,7 billions yen correspond roughly to 1 million digital cameras sold. In other words, over 7% of the ILC market.
Even factoring out the compacts, as they barely have few models that percentage would not fall too much. But I think their actual market share is lower, and those numbers include sales other than digital cameras.
Here's another approach; BCNRanking estimated a market share of 4.5% for DSLRs, and ~8.7% for MILCs. That means ~48,500 DSLRs (~2.5 billion Yen) and ~63,000 MILCs (~2.5 billion Yen) with a total average value of ~5 billion Yen.
1.5 lens sold on average for each means ~150,000 lenses, with a total value of 3,375 billion yen.
In total - under 9 billion Yen. Sure, there must be other sources but it's a far cry from the 75.7 billion Yen for the entire Others.
P.S. It's late and I'm tired, so you might want to double check my calculations...
Taking into account average price per unit and average number of lenses per body from CIPA figures, otherwise same assumptions as yours.
DSLRs: 468,206,857,000 JPY ÷ 10,549,890 units = 44,380 JPY per unit (you took 44,000)
MILCs: 137,116,746,000 JPY ÷ 3,289,278 units = 41,686 JPY per unit but the average price of a MILC (24x36, APS-C, µ4/3, 1" and 1/1.7") is much more than that of a Q; let's assume 30,000 JPY for a Q (you took 40,000)
Lenses: 223,495,664,000 JPY ÷ 17,067,842 units = 13,095 JPY per unit; again, let's retain this price for DSLR lenses and discount it for Q lenses and retain 9,000 JPY
Average number of lenses per unit: 22,927,892 lenses ÷ 13,839,168 bodies = 1.66 lens per body (you took 1.5)
48,690 DSLRs x 44,380 JPY per unit = 2.16 bn JPY
724,775 MILCs shipped to Japan x 8.7% market share = 63,055 Qs; 63,055 Qs x 30,000 JPY per unit = 1.89 bn JPY
48,690 DSLRs + 63,055 Qs x 1.66 lens per body = 80,667 K-mount lenses + 104,466 Q-mount lenses
80,667 K-mount lenses x 13,095 JPY per unit = 1.06 bn JPY
104,466 Q-mount lenses x 9,000 JPY per unit = 0,94 bn JPY
2.16 + 1.89 + 1.06 + 0,94 =
6.05 bn JPY as total sales of Ricoh in Japan under the Pentax brand.
A far far cry indeed from the 75.7 bn JPY for the entire 'Others' business unit. Only 8% of them actually.
