Experiment

[Ron Evers]

1. This is a shot taken with a Canon FD 50mm 1:2 macro @ max magnification.

2. Same lens with a 25mm extension tube for 1:1 magnification.

3. Same lens with a Soligor 2x telconverter for 1:1 magnification.

The telconverter gave me more working distance than did the tube but as you can see it also degraded the image in comparison. Unfortunately, I did not think to measure the end of lens distance to the subject when I did this.

All shots were @ f16.

Yes.. nice experiment. The one with 25mm extension tube gives better result compare to the 2x teleconverter. Typically we use extension tube for macro shots magnification and teleconverter (i.e. 1.7x, 2.0x etc) for telephoto/zoom magnification.
