i got the calc. for max. working distance, thanks.
some more questions, forgive me that i am new to macro calculations;
(all numericals for raynox 150 attached to the lens)
1- if I'm closer than 210mm (for FL 210mm), then is magnification bigger than 1:1? if so what is the relation?
2- if I use less FL than 210mm, eg 100mm, should I make the distance to 100mm in order to get 1:1?
3. what is the relation with diopter and aperture value? (to imagine DOF)
4. is diopter fixed for raynox? that is can 8 diopter raynox 250 be ajusted to eg 5 diopter to increase working distance?
Thanks

thanks for contributions Banjo,
then small working distance and narrow dof make raynox hard to use :D

silverelantra,
i see that you used 200mm for these shots, what was the distance between the object and the lens tip?

audiobomber,
thank you very much for suggestions.
I had thought the same cost and convenience benefits o raynox instead of a true macro. But you're right.

i realy think to get a raynox intead of a 100mm macro.
am i on the wrong way?
