Tim, I am curious, since you have both : what would you say of the benefits of using the 1.4TC with a 60+ext.tube, over a 100mm+1.4TC (which already fits naturally)?
Hi Luko,
You make a very valid point and is one which had not escaped me either...
My initial (dry) comparison between the 60mm and 100mm appear to show an improved working distance with the 100mm and TC combination, even when using the extension tube. I suspect focusing will be a nad quicker with the 100mm too. However at this level of magnification I am more inclined to set the lens to MF and adjust the working distance to achieve sharp focus rather than test the AF. I think a monopod or tripod will be useful too. In fairness, maybe the 60mm, TC and tube combo offers a more cost effective super macro solution but may be a compromise over the flexibility and image quality which the 100mm and TC offers.
With either option behind a Nauticam 60 macro port I can also bring my 67mm INON UCL's into play. Happily, I can also use the UCLs topside too as the 100mm filter thread is 67mm.
