"I do a lot of flower photography and most of the times I need more control over DOF than what a normal lens can give. The TS-E was an obvious choice since it lets me control my plane of focus and lets me maximize my DOF and still keep the background out of focus.
I have been shooting with this lens for over a couple of months now and find this lens on my camera most of the time. It has a minimum focusing distance which is enough to let you get close to the flowers. I dont need any extender or tubes most of the time."
