Tips for gettingthe most out of the 100mm 2.8

1 Use a tripod. Because when working close to the subject minute movement will alter the focal plane and sharpness of the image. One thing that can help is a focusing rail. I tend to use a tripod ring on my 100mm 2.8 with a lone quick release plate this enables me to move the set-up small amounts with out resetting the tripod.
2. Use manual focus when ever you can. It will give bteer control over the point of focus
3 Use a flash optimal is the twin light but it is pretty pricey. A 430ex mounted on a flexable flash will enable you to adjust where the flash is directed and how close to the subject it is set. Reflector disks help difuse the light or redirect it as needed.
4 Patience and practice Macro is simple enough but it takes time to develope the skills.
5 Additional items. Extention tubes are the cheapest and simplest way to increase your ratio. no need to buy Canon as there are no optics involved. These will reduce the focusing distance dramatically, enabling you to move very close to your subject. ( might not work too well for skittish insects)

Reversing rings to either add a second lens reverse mounted on to your primary lens or to reverst mount your main lens. Again this may not work too well with insects as your focal distance is very short.
