Yes, but the ZM 15/2.8 is a whopping 4.6K USD and the ZM 21/2.8 doesn't perform too well on the NEX 7 24MP sensor. So barring Sony making allowances for the microlens array, I'm not so sure how well they would perform.
Also, the ZF/ZE 15/2.8 is quite a lot cheaper.
ZF/ZE is much bigger in size right?
i guess we'll have to wait and see what Sony releasing.
