For me, when buying only the "shoot and view" function was actually important. Unfortunately, it is so that the transfer of the image to 18MP resolution about 15-20 sec lasts. That makes it the customer in a shooting impossible to follow the action live. With a reduction of the resolution can be this time devalue up to 5 sec. But who would make such a bad photos. Who, of course, a camera with a second SD slot has for which he can choose the resolution freely will also be happy with this feature. Therefore, there's just a small devaluation. What now but must not happen is that after a battery change resulted in no more saved. Therefore again a star deduction. All other functions I can not rate
My conclusion: Use only in second SD slot, never as the main card.
