Take a look at these macro extension tubes.

Hmmm, I don't think it's a question of extension tubes, there's something wrong with the camera or lens. Mine achieves 1:1 at about 30cm from the subject (using a 7D)...and can focus a bit closer tack sharp. Same subjects:

Less than 30% crop on both pics.
I am confused. The spec says the minimum focusing distance is 30 cm with a magnification of 1x. So can you state the problem again?

+1 I prefer shooting wide open. Couple I shot wide open handheld in my garden last week.

This one right place right time. Was shooting this flower and the wasp landed on it, shot a few frames and off it flew. Bright sunlight, to freeze the action and enough depth of field 1/1600sec F9 meant ISO5000!!!!! Straight out of the camera look how useable that is! Its ridiculous. 5DMKIII with 100mm macro L

My point is that even without extension tubes farhanajahan's lens/camera combo should be performing better, so there must be something wrong with the lens or camera...

Did you AFMA the lens in macro shooting mode? If the lens works better on another camera then it is not the lens but something to do with the camera...
