Though Sonys crazy QX10 and QX100 lens cameras can attach to most smartphones, the company naturally favored its own Xperia Z and Z1 handsets by creating custom cases for those devices. Now its doing the same for its crazy-large 6.4-inch Xperia Ultra Z, according to our sister Engadget Chinese site. A new attachment cover in black or white will fix either camera to its latest phablet for HK$238 (about $30) on top of the price of the QX10 ($249) and QX100 ($499).
