[QUOTE="Pierro, post: 120814, member: 8517"] If you want the best IQ you can achieve, and it seems thats what you want if you're trying to emulate someone, then you're gonna have to stump up the coin for a true macro lens, which has a ratio of 1:1, that is, an insect that is 1/2" long in real life, is 1/2" long on the sensor. If you buy say a 50mm macro 1:1 lens, attaching a 50mm extension tube, or attaching a 2x TC will get you 2:1, which is double the size of 1:1 A TC will cost you light and IQ due to extra glass, and extension tubes will just cost you light, as there's no glass. As you add more tubes, it gets harder and harder as the light gets less and less, and the image gets bigger. Personally, if i was going for that kind of mag, I would use a tripod, macro rail, mirror up, remote cable , ring light and offboard flash. Then you've got the problem of DOF. At those silly mags, DOF will be starting to get into MM's or fractions of MM's, which mean at even f11 or even f16, you're only gonna get the eyelashes in focus, or best case scenario, the eyes. That means you're gonna have to start focus stacking, and take maybe 10 shots ( as a rough guide ) at varying points from front to back of your subject to get a decent photo from it. If you're only ever going to try front on / head on shots, its not so important about getting the whole insect in focus, but if you shoot the subject 3/4 on, or side on, you will probably need to focus stack [/QUOTE]
