Only the very expensive 200mm F2 spades really better, but the 5000 objective, 100mm F2.8 Macro IS remains a key objective for the lovers of the sharpness and the macro.
Be careful though not to forget to switch the beach the AF button, otherwise improper adjustment can play surprises you, eg if you miss the button on 0.3m-0.5m Af skate and this is normal, just have to think back on a "full";)
If you hesitate with the non-IS version, know that it brings a real interest and it should be tested to be believed! a clear picture has 1 / 5sec .. staggering.
