You jerks just cost me $5xx. Really looking forward to the 100mm macro lens coming. Am thinking about starting a 365 macro project.

What would happen if you put extension tubes on a 100mm f/2.8 macro? Would the camera implode? Or would you simply get greater magnification?

I'm asking because I have a macro lens and it seems like some of these really awesome photos get so much more magnification that I'm used to seeing.

I've done it a few times. It is really hard to use. The DoF is razor thin even stopped down and it's really really hard to keep your focus without a tripod. It does feel a bit like a microscope though. I didn't have any examples to show you so I took some. Because I don't have anything better to do at midnight on a Sunday.





Here is the lens without extension tubes. This is uncropped at the lens's minimum focus distance.




This is with the extension tubes, also at the minimum focus distance uncropped. Please forgive the inconsistent lighting between the photos. I was holding the flash and couldn't get it to match exactly. I also had to put the flash almost against the table for this shot which made it look really red. Keep in mind that I used a Kenko extension tube set, so this is third party air.

EDIT: I should probably mention that this is on a full frame.

Just what I wanted to know. Thanks Wooten for going to the effort!

It's horribly cliche, but this is a self portrait I did by holding my gripped 7D and looking at the mirror in the back of the body till I could see my eye.

7D and the 100 2.8 USM. Not a great picture, and I have a mad ugly eye, but I'm happy I managed to hand hold self portrait my own eye!



Hah, I did the same thing when I got the 100/2.8.



I'm really thinking about getting some of the extension tubes. I want to see atoms.
