Hi Laurent, the longer the focal distance the further you can get from your subject with the same magnification. So 180mm is currently the best dedicated macro lens for not disturbing these little creatures. But 100mm is also pretty good, it just means you have to be better at not scaring them away.
Aperture 8 is considered shallow depth of field in macro photography with most images being taken from f10 up to f16 to get the whole subject in focus. It's a matter of personal taste. I try to push the boundaries of shallow dof sometimes getting down to f2.8 if the wings of a butterfly are perfectly lined up with the focal plane of the camera. This gives you the benefit of having a nice out of focus background with a very sharp subject, but it's tricky to get that subject all in focus below f8.
Thank you all for your very kind comments. I'm impressed this image was so well received.
Cheers,
Tim
