At launch, how many FE lenses are available for it? For an FF I'd be looking at least 14-24 and 25-70 and 70-200 to be covered with 20, 30, 50, 70 and 105 macro primes, just to make it a functional system.
http://www.dpreview.com/news/2013/10/16/sony-announces-five-full-frame-e-mou...dated-70-200mm Quote: Sony has announced no fewer than five 'FE' full frame E-mount lenses to accompany the A7 and A7R. First up is the FE 28-70mm F3.5-5.6 OSS, an image-stabilised 'kit' zoom for the A7. There are three premium lenses with Zeiss badges: the FE 55mm F1.8 ZA Carl Zeiss Sonnar T*, the FE 35mm F2.8 ZA Carl Zeiss Sonnar T*, and the FE 24-70mm F4 ZA OSS Carl Zeiss Vario Tessar T*. The fifth lens is a 'G' class telezoom, the FE 70-200mm F4 G OSS.
Sony has also updated its Alpha-mount fast telezoom to make the 70-200mm F2.8G SSM II. This lens gains faster autofocus and updated 'Nano AR' coatings, and is now specified as dust and moisture resistant.
The 28-70mm F3.5-5.6 OSS is the basic 'kit' zoom for the A7, and won't be sold separately. The 35mm F2.8 will cost $799, and be available in December 2013, while the 55mm F1.8 will cost $999 and be in stores January 2014. The premium 24-70mm F4 OSS Carl Zeiss standard zoom will cost $1199 and go in sale in February 2014; pricing and availability of the 70-200mm F4 OSS telezoom are still to be confirmed.
