The 60mm seems to be appearing in shops, so as always we start thinking of whats next. Bearing in mind they will probably make another prime, and go for a focal length that makes sense on NEX (and possible not make sense on m43), I think there are 3 possibles here: 24mm - This seems like a no brainer. NEX needs a less expensive 35mm equiv option, and m43 needs a less expensive 50mm equiv option. OK, so it's not that much different in FL that the 19mm they already make, but no one though having both 28mm and 35mm on Film SLRs was odd. 12mm - An ultra wide prime on NEX, a cheaper alternative to the Oly 12mm on m43. There is a common request for a UWA prime on m43, so I would expect there is demand for one of these from the NEX community too, and the Sony ultra wide zoom is not exactly affordable. On m43, I'm sure many people would be interested in a 12mm that is cheaper, if slower, than the one we've got already. 90mm - 135mm equiv on NEX, so good for head and shoulders portraits, and a fast tele for m43.
