poor review - lacking basic photography knowledge
I can forgive your use of 'sharpness' when you mean 'optimum focus', but I'll stick to a reviewer who knows what a focal length is. The 'Multi-Target Auto Focus' surely does not 'shoot seven images at seven fixed focal lengths'. If it did, it would provide a choice of compositions. The fact that you even listed the focal lengths in terms of 35mm equivalents should have given you some indication to what 'focal length' refers to? The feature actually takes seven shots at different focal distances. This is in essence just auto focus bracketing, and has been around since the Contax N1 of 2001.
