With the new cameras announced today it was also announced that there would be a firmware update for the NEX3 and NEX5.
At first I thought ho-hum just some new picture controls. However in the article over at Luminous Landscape they said the new focus peaking technology would be in the update! Now this is something to get excited about.
"There's good news. The new firmware found on the C3 will be available as an update for current NEX-3 and NEX-5 owners, so if you are keen to have Peaking this will be available for your previous NEX camera around the same time that the NEX C-3 is announced."
