Hey, how come we are agreeing so much? But, yes, exactly. I particularly 
like my CF tripod, it seems to eat vibration rather than creating and/or 
augmenting it. I really think that is more important than the weight 
advantages. I do know from trying several out that not all CF tripods 
are as good in this regard as others.

Oooh, I just KNEW you were going to say that. I just happened to be 
looking at some shots I took with the 50/3.5 when this topic came up, so 
that's what I posted. Most of my macro shots are with 90, 105 and 135mm 
lenses and I find no more problem with them. As you say, I use tripod, 
hand hold to absorb vibration, shoot when there is little or no wind and 
often wait for a quiet moment when the subject isn't moving.

I much admire your insect shots, but have never yet been moved to try 
such things. I have a number of insects in my flower shots, but often 
didn't know they were there until I looked closely at the results! My 
few shots specifically of insects are opportunities that presented 
themselves, rather than something I went looking for. There is a big fat 
spider like the ones others have been posting about in the front yard. 
Maybe it needs its picture taken.
