This is not meant insulting by any means, but: Have you ever used a macro lens that goes up to 1:1? I checked your profile and I saw none listed.


What do you want to photograph with the MP-E anyways?


I recently started using the new 100mm IS Macro lens. While handholding is generally possible, at 1:1 a steady hand is definitely required in order to keep the focus plane where you want it to be.


At higher magnifications - 2:1 or 3:1 you either need really really fast shutter speeds or a tripod. I recommend a tripod..


I doubt you could get many satisfactory shots handheld at magnifications higher than 2:1, but that of course depends on the situation and what you are shooting...
