So, how do I tide the need for a true macro lens?
From David A. Ziser's book, Captured by the Light, a great book for wedding and portrait photography I should add, I got the idea of not putting the camera on a portrait orientation when my external flash is on the camera (The section in the book that I am referring to is "Shadow Problems with On- and Off-Camera Flash.). You have a lesser number of options for bounce flash if the camera is on portrait orientation. So, instead of getting the picture vertically, David suggested to get the shot horizontally and just crop the picture in post. With the large pixel count in current camera models, you will still be left with a lot to work with even if you crop the picture.
So, this made me think: right now, I'd like to get an all-around portrait lens first before I start thinking about getting a macro lens. But since I get 18 megapixels worth of image with my 7D
