I am planning to buy the Olympus EM-5 camera setup and wondering if I should buy the 14-42 or the 12-50 mm lens. My main use for the camera is for still photography U/W. When looking at the focal range for each type of lens, I see that the 1250 lens has everything the 1442 mm lens has plus more. Does anyone have any feedback on which lens to buy for use U/W for macro or if I should buy both? (The question can be asked, is there a reason to buy the 1442 lens if one already has the 1250mm lens or should they buy the 1442 mm instead of the 1250?)
