 Re: Official: Sony A7 and A7r full frame mirrorless announced! | |
24-70/4: five aspherical elements and one extra-low dispersion element, Tessar \'concept\' (?), moisture proof, 430 grams so this on the a7r is 900 grams, circular diaphragm (so nine blades most likely), 10/12 config. That sounds good.
