这是在黑这个头啊 If you want to do serious macro work, any 40mm lens is a bad idea because you have to get too close to your subject to get close-ups. You'll block your light and your pictures will see the image from an unnatural point-of- view. At its closest, there will be less than 2 inches (48mm) between the front of your lens and the subject with this lens! 40mm macro lenses are really only useful for slide copying where the light comes from behind. That's why this 40mm lens is mostly for use as a general- purpose normal lens, with the ability to focus very close for occasional use
