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:

http://www.ruddyflorentino.com/#!untitled/zoom/c3c1/image1cbf

Both the first two images look very noisy for the MkIII, suggesting the light and possibly the shutterspeed was low. Certainly the third image looks like there may be some motion blur, although the ISO seems to be much lower by the lack of obvious noise. What shutterspeeds and ISO settings were you using and did you have in-camera noise reduction switched on?

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?

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...

Shutter speed 1/30, ISO 1600 during the sunset time, so kind of low light in my backyard...... . first 2 pictures are noisy because i did more then 30% crop.

Ah ok, that probably explains it. Did you also shoot them in RAW and then in post process not apply any noise reduction?
Was there a little air blowing? Don't forget that it takes only 1-2 mm to get the animal out of focus in such close distances.

Not sure what happened to the body of my previous message, but if you were handholding at 1/30th, then it will increase the risk of motion blur/camera shake. IS would probably be less effective at macro distance, although I haven't tried it. Also, even if on a tripod, any movement of the subject (such as branches blowing in the breeze) will cause motion blur and it doesn't take much with macros to make a difference. Also, cropping won't increase noise levels (although it might be more obvious in cropped images reduced than uncropped images reduced in size), but under exposure will certainly increase noise levels and any motion blur will make it more obvious, as it will potentially be the sharpest part of the image.

Haven't used this lens in a long time, so pulled it out and shot these several days ago. 7D, f/9, ISO 400, handheld, ambient light. 1st @1/80s, 2nd @ 1/125s.

I enjoyed this post and the pics that everyone uploaded. I'm going to use this lens more often. We have a butterly that
has been in our yard a couple of times and I hope to take it's pic next time it's here looking for food.

If you can figure where they sleep you will have a very still muse. There is a bush in my garden where some butterflies sleep. When they do, I go nuts clicking pics.

Times are hard when you have to turn to cicadas as models. On the plus side, they don't charge for their time and you don't need a signed model release form.

Both photos were shot hand-held in available light (no flash) at high ISO (1600 for the full body portrait, 3200 for the head shot).

Very nice! I like the 2nd one the most. :)
Is it true they only come out once every 17 years?
