I am new to macro and I picked up the Kenko tubes - 12mm, 20 mm, and 36 mm. I've been playing with the 36mm mostly.
Out of curiosity, for those of you using these tubes, which one do you use most often, and if you stack, which combo of tubes are in your stack?
I guess the most common response will be "it depends on your subject". But as a new user, is there a "most common" tube you use or most common stack you use?
