what do you think of this?
(SR5) New Zeiss 24-70mm FE (Full Frame E-mount) lens coming too with the NEX-FF in October! | sonyalpharumors (http://www.sonyalpharumors.com/sr5-new-zeiss-24-70mm-fe-full-frame-e-mount-lens-coming-too-with-the-nex-ff-in-october/)

I would rather have the 16-70 F4.0 ...far more useful range for me!! But Zeiss is going to be pretty costly I think! An F2.8 24-70 from them will probably be close to half the camera cost!!
