Jarmo,
How easily could you have pulled this off with other camera-lens combinations you've had in your hands before. In discussing the gems images of flowers made by Klaus, the idea that the lens' uniqueness if only a minor part of success in such pictures.
Of course, no even the most exquisite lens can guarantee its owner a path to a great photograph, unless of course the photographer already possesses the qualities needed to leverage such a tool.
Still, I think that this shot is pretty demanding and a lot of people might not be able to do this with their own lenses, even though skill and aptitude can get one somewhat in the ballpark.
I think sometimes the lens should be given praise and recognition too! Is this such an occasion? Do you owe it much in this instance, or could you have easily delivered no matter what you had in your hand at the time simply by positioning and timing the shot for the most opportune moment, given whatever camera you were stuck with?
