This is a free download from Rolleiflex US and gives some information about close-up work with the 6000 system.

I'd check how close you can get with just the standard camera and lens set up.

My RB67 will get you to almost a head shot filling the frame.

I'm sure the Rollei would do something similar.

Extension tubes tend to be used for almost macro work.

it came the other day so I have had a little play ,and on my 150mm lens I can get the whole of the face in, filling the frame up ,I can focus from the film plane 30"up to 40",with the 150mm lens, and with the 80mm lens I can focus from 14"up to 16" and get some of the palm of my hand .the camera has a great metering system in it so I have no trouble with ambient light ,but with flash should I open the aperture by one stop or two ,its a 34" extension tube .

I think itís less than one stop for both, Paul. Could you meter the same scene in daylight with tube on and off, and note the difference? You could try that for both lenses. Presumably the difference will be the same for each lens whether it is daylight or flash.
