Review Excerpt

  • Much improved, sleeker camera design doesn't mimic the competition; Sharp 3-inch vari-angle LCD screen swivels to the side, letting you compose shots from difficult angles; Brighter lens performs better in low light; Fast burst mode; Full HD movies.

  • Some photographers will miss having an optical viewfinder; Slower autofocus and single-shot cycle times when capturing RAW images; Shallow buffer; No one-touch video button.
