          |  135mm f2 vs 100mm macro?     Post time: 1 月 22 日 |  |

          | I want to have a medium to long tele lens to take portraits and landscapes. Canon 135mm f2 L is an excellent dream lens of mine. I have a 100mm f2.8 macro which is already good enough. I can take head shots at a very close distance. But does 135mm f2 give me significant advantage over the 100mm macro? Is the focal length too near 100mm? You know the 135mm is not a cheap lens.
