Originally posted by 6BQ5 Don't forget that mirrorless is a brand new thing relatively speaking. New things typically get the lion's share of marketing. They have to in order to drum sales to recover development costs. Sony makes a "buzz" because they pour a lot of marketing dollars into ads and campaigns. Ricoh does a lot less and therefore requires less money to recoup costs. That may be why we're seeing so many sales on K-3 and K-5 IIs models. Ricoh can afford it.
If mirrorless are really cheaper to make, similarly specified mirrorless cameras could sell for cheaper than SLRs. The reason we haven't seen a rush to mirrorless, in my opinion, is that there are a lot of very cheap SLRs out there. Discounted D5200s and D3200s or whatever the bottom of the barrel, couple of generation old Canon SLR is.
If you could get an A7r for five hundred dollars cheaper than a D810, wouldn't you consider it?
I don't know how much cost savings brands achieve by going mirrorless, but supposedly it can be pretty considerable.
