What I hate about these figures is the use of digital compact cameras as the base quantity. Who these days carries a digital compact? Well, I own a few, and the kids take them places - Scout camps and the like, where a camera with the capacity to turn off and be easily used trumps something that wants charging every day.
Here's the stuff from the website (
http://www.cipa.jp/stats/lens_e.html, and using camera link as well), every 4 (whole) years up to last year:
1999 FP camera 4,236,880 SLR lens 5,647,470
2003 .................2,280,801 ...............4,610,986
2007 DigitalSLR 7,547,295 ILC lens 12,750,668
2011 ...............15,742,039 .............26,265,690
2015 ...............13,058,854 .............21,494,595
If you want to know SLR lenses in the last 3 quoted years: 3.9 million, 5.8 million, 5.7 million.
In short, don't lose sleep yet. Plenty of real cameras out there, plenty being sold, numbers higher than 15 or so years ago.
Can we all get back to discussing our usual spats now?
