Charlotte,
The flower macro was more coincidental, flowers represent a small part of my photos, I do not specialize (yet?).
What attracted me, was the fact that this kind of work is totally different to what I did (and to most I saw). I see it as an occasion to learn to see in a different way, thanks for that.
For macro - the lens is a tool like the camera attached to it. Among the currently available (new) macro lenses for DSLR there are no really bad ones I am aware of.
Glad you like this one - I see it as a fun macro as it adds a different view to the natural environment.
Best regards,
Michael
