Using a Zoom Lens for Macro

[rcolman 0]

The oly 14-54 zoom is a great all-around lens, and I use it behind a dome port on an E-330. When I see a macro subject, I crank it out to 54mm and get as close as I can, but it is not macro.

 

The specs of interest are (2x equivalent):

 

Angle of View: 75° to 23°

 

Closest Focusing Distance: 8.67" (0.22m)

 

Maximum Image Magnification: 0.26x (0.52x 35mm equivalent)

 

Does anyone know whether it would be possible to get additional magnification by using it behinda flat port, perhaps with a Woody's diopter in addition.

 

 

1) what would this do to wide-angle, and

 

2) would the diopter provide a bigger image etc.

 

I would like to investigate before putting out money for the additional port
