Focussing will be affected because of the very shallow depth of field. But the perspective will be very different if your camera shift just half centimeter when you are that close!Originally Posted by EiRiK
Perhaps we all have different things in mind when we talk "macro". To me, "macro" is not about a bouquet of roses, or even a rose. I take it to mean for example the "heart" of a rose 1:1 if not 2:1. Maybe other people have the ability to hand hold a camera that close ( I use anything from a 50mm macro to a 180 mm macro) I once tried to use a canon 60 mm (I think! maybe it was 65 mm) macro to focus on some words on the box hopusing the lens when I visited Cathay. I just could not hold the focus! Maybe others can.
And I do not agree with HWChoy that it is " not helpful for the uninitiated to read words like "mandatory". On the contrary, I think it is not helpful for the UNINITIATED to have too much choices when he/she knows very little. To the "experts", do anything you want as long as it work for you. But to students of photography like me, I choose the method that will give me the best chances of getting the shots. That may mean forgoing a running ant. But so be it!
There are obviously differences in opinion, and I can only suggest that the novice try to find which method works.
