See what Bloomberg reports:-
http://www.bloomberg.com/news/2011-09-07/canon-clinging-to-mirrors-means-opportunity-for-sony-cameras.html
Some quotes:-
"The two Tokyo-based companies use mirrors in all cameras with interchangeable lenses, a technique Sony Corp. (6758) is shifting away from. As a result, Canon and Nikon’s combined share of the Japanese market has fallen by 35 percent, while Sony’s share has doubled, according to estimates at research firm BCN Inc."
So, Sony rises up and the big two boys are threatened. And as Bloomberg suggests, clinging the mirror means loss of market share, although DSLRs are still lucrative.
Besides, the Pentax Q is also mentioned:-
"For example, Hoya Corp. (7741)’s new Pentax Q weighs 200 grams and its body is smaller than an Apple Inc. (AAPL) iPhone 4 in terms of width and height. By comparison, Canon’s entry level EOS Rebel T3 weighs 495 grams. "
After all, my Congrats to Pentax for having a mirrorless so that they can now bite the pie from Canon and Nikon! ;-D With the smallest ever ILDC body and system with "comparable DSLR image quality" (as claimed by Pentax and then firmly believed by those brand fans), I am almost sure that Pentax will soon become the market No.1 in the near future! So, let's think how we should celebrate then! (Lol..)
