Yeah...I went to the Wooden Shoe Tulip Festival this year and took my 50-135/3.5 manual focus + polarizer as my "general lens", and a 24 as a wide and a 90mm macro...tulips, everywhere...I found the 90mm macro was just too wide, and I'd have to get down on my still-kind-of-bad left knee to get the kind of isolation I wanted...I know what you mean...looooong lens for closeups makes backgrounds narrower in angle, easier to control, "tidier" with less effort dodging the other flowers. if I go to Schreiner's, I think I will go with my 300/4, which focuses down to about 4 feet on its own, and add a 12mm extension tube if needed, so I can get some nice "isolation shots" of blooms without needing to be super-close.
