Lenses for Flower Photography

I have brought a variety of lenses to use for flower photography and gave most of them an outing yesterday. The pansies are taken with a 70-200mm lens with an 25mm extension ring, the Butterfly orchid with the 24mm tilt and shift, the Dark Vanilla orchid with a 50 mm macro and the Rampion with the G12 macro mode. The light was very harsh for the pansies and getting a bit low for the two orchids.
