Sony may be smarter than we are giving them credit.
When they launched the A7 and A7R, they expected the A7 to heavily outsell the A7R, as most people dont need 36 MP, but the sales figures were the opposite: the A7R heavily outsold the A7.
The A7R is the cheapest way to get your hands on 36 MP and you can put lots of old lenses on it. Is everyone really buying the A7R because they want a small camera or because they want 36MP, lots of lens options and a low price? If the latter, then some large lenses that realise that resolution is quite sensible. Its not what I want, but I wonder if they have realised how 'megapixel and resolution' obsessed the market actually is.
