This is the first wide-angle that actually works without vignetting on my Sony CX-560VE. (The 560 is in optics identical to the 690 or 700, so that there should be no vignetting even here.) The half a point deduction there, because after only slight zooming the focus disappears completely (and not readjusted's) and because, unfortunately, no lens cap is included, but you must always (with practical snap closure) grab the lens in the supplied pouch to protect instead. When the lack of "zoom-ability" is aware and is willing to accept this, which is a high-quality wide-angle lens (- albeit only 0.8x -), which is still the necessary modicum brings more into the picture for a reasonable price in borderline situations.
