Hi Philippe,

What will you be trying to photograph?

You'll need a bellows, a micro lens in the 80mm-135mm range (Photars,  
Micro Summars, enlarging lenses and the like), or a low magnification  
microscope prepared for microphotography (that's how it is actually  
called when you go larger than 1:1). They have trinocular optical  
systems that allow observation and photography at the same time, by  
means of a camera attachment that 'sees' the same as the observator.

Lighting is also dependent of the type of object you want to record.  
If it is translucide, or allows transmittive illumination, the  
lighting system of a microscope is enough. If you need lateral  
illumination you will need to use one or two flashes from the sides,  
better if with a condenser lens (loupe) to concentrate light on the  
object. Sometimes a ring flash can be enough, and some of them even  
have a modeling lamp to allow precise focusing and light positioning.  
A polarizer can be necessary for some subjects.

Macro and micro photography can be very fun, and you'll have to  
experiment to find the best solution that works for you.
Cheers,

Ed
