When these people switched to dslr they forgot to divide the focal length of their macro lenses with 1.5!
This picture like many other was taken with my NikonMicro 60mm. I would not pick other lenses even if I had them there.

Hi ruchai
Why do you say there is optimum distance from the subject and not the more further back the better, magnification is a combination of the focal distance from the subject to the lens and the focal length of the lens, so unless you have a specific reason to get physically very close to the subject a longer focal length macro lens has the advantage of obtaining the macro image size at a greater distance, therefore less stress for the subject. As I pointed out, a 90mm 1/1 macro becomes a 135mm 1/1 macro on a Nikon DSLR, (probably similar on Canon, not sure.) For insect macro work I would think being able to shoot at 1/1 on a 135mm lens is very useful and desirable.
