I was going to buy the 90 macro, but after buying 24-70 2.8 GM, 70-200 2.8GM, and 100-400GM and 2x TC in a short period of time, I couldn't justify the 90 macro at this time. Definitely on my list of future purchases though.
I'm actually going to try the extension tubes with the telephoto lenses just to see what happens.

I think you'll be very surprised at the macro capability of the 100-400GM. I've not tried macro with it and the 2.0 but
will probably be awesome too.




This is what a typical day at Windansea looks like out here, there are 4 1/2 photoshoots going on in this image, with two more underneath me, shooting against the rock I'm standing on here. The woman in white is waiting for the photog to return with a pop up changing booth. You should see what the reef at La Jolla looks like at sunset too. It's not uncommon to see people at the potholes with their tripod legs overlapping.
