Can you shoot small flower with the extension tubes. I understand that the larger the film size the harder it is to get 1:1 since 1:1 on 35mm is much smaller a area than a 1:1 on 4x5.
My dentist uses a "cord" on the end of which is a very small digital lens (smaller than the end-cap of a ballpoint pen).

With this, he can get down to just the crown of of a single tooth to display on his 17" monitor in live colour (in real time), a movie clip, or get a still of it for discussion of any defects in the tooth, old fillings, and work needed: fabulous!

Horses for courses.
