  • Weve already sorted through the specs, and laid
    our hands on its rather sexy frame, now
    Fuji?lm'soffering up a more palatable price tag
    than we expected for its throwback X10 shooter.
    Startingsometime in early October, the X100's
    more affordable little brother will set nostalgic
    point-and-shooters back 599.99 about 100
    bones less than the estimated 715 to 860
    ballpark we threw outback in September. If you'll
    recall, the X10 packs a 12 megapixel EXR CMOS
    sensor, f/2-2.8, 28-112mmmanual zoom lens, up to
    12,800 ISO sensitivity, 1080p video, an optical
    view?nder, and pop-up ?ash. Noword yet on a ?nal
    release date. Full PR after the break.
