" Meanwhile, the economic downturn has made the less-expensive mirrorless cameras a more appealing purchase for those who think that a cell phone is insufficient."
Not sure I agree with this statement. Naturally, some entry level mirrorless cameras are less expensive than some entry level DSLRs but, generally speaking, mirrorless doesn't seem less expensive.
Mirrorless lenses, for brands like Sony, are more expensive than equivalent DSLR lenses so when you talk about a camera system, mirrorless can easily exceed the price of a good DSLR.
Wow! What is Nikon thinking?
I know I'm just repeating what others have said but $1100.00 for a fixed 28 mm 2.8 lens just isn't going to be a big seller.
