As for the subject, I took Bryan's advice and bought some roses at a local florist. Sure enough, the flowers worked well for my test. But better yet, my girlfriend loved them. So if you're ever looking for a good macro subject, keep this in mind – your significant other will likely appreciate any excuse you have to buy more flowers.
For lighting I used one camera-mounted Canon Speedlite 580EX set to ETTL mode and diffused by a RoundFlash Magnetic Ringflash Adapter. While I knew the Roundflash would produce a rather flat look to the image, I was curious to see how the reflections of the ring light would show up in the water droplets. As you can see, it created a relatively interesting and not too unflattering reflection. However, I'm sure it's a matter of taste.
The tripod-mounted EOS 5D Mark III's camera settings were f/10, 1/200 sec and ISO 200 - 800 (depending on the shot).
This first example shows the central part of the rose using the Canon EF 100mm f/2.8 USM Macro's minimum focus distance.
For aesthetic purposes with this particular subject, I would usually just stop right there. I don't believe getting more magnification out of this subject will improve the image, but for the purpose of this test I wanted see just how much magnification I could get out of the equipment I had at hand. Consequently, I added all three Kenko extension tubes (12 + 20 + 36).
The extension tubes reduced the minimum focus distance thereby increasing magnification with the consequence of losing infinity focus. That's not a problem, of course, as we're utilizing the opposite focus extreme. The following image shows the difference that the extension tubes make.
The central part of the rose is now considerably larger in the frame. Keep in mind, though, as our minimum focus distance decreases, so does our depth-of-field. At this point, depth-of-field is already very limited even at f/10.
For the final image, I mounted the Kenko 1.4x teleconverter behind the lens and then mounted lens/teleconverter in front of the extension tubes.
As you can see, the addition of extension tubes and the teleconverter have had a huge effect on how much magnification we can get out of the macro lens. The combination is a little cumbersome to work with, so using a tripod is highly recommended (if not completely necessary) if you are wishing to try this for yourself.

Nine loyal fans will receive choice of lens, be featured on Sigma website
RONKONKOMA, NY — March 4, 2015 – Are you a loyal Sigma camera and/or lens owner? Sigma Corporation of America is giving away nine lenses to its super fans from now until December with the launch of its #SigmaSuperFan contest.
The #SigmaSuperFan contest is open to all Sigma camera and/or lens owners, and entrants will be asked to share “what motivated you to buy a Sigma product and why are you a super fan?” for a chance to be a monthly winner of their choice of three lenses. Winners may choose from the Sigma 18-300mm F3.5-6.3 DC Macro OS HSM Contemporary, 17-70mm F2.8-4 DC Macro OS HSM Contemporary or the 50mm F1.4 EX DG HSM, and will be notified on or about the first day of each month by a Sigma representative.
“As part of the contest, we’d like to hear from all of our loyal Sigma fans about their first encounter with Sigma, and how the relationship evolved into being a super fan,” said Christine Moossmann, Director of Marketing for Sigma Corporation of America. “Our family-owned business owes much of its success to the devotion of these photographers, and we’re using this contest as a way to engage with our community and thank them for their loyalty.”
Sigma is encouraging all U.S.-based photographers who own two or more Sigma products to enter the contest. Entries will be accepted from March 3 to November 16, 2015 on the Sigma website, and participants will be asked to fill out and submit a brief entry form. Each participant can only submit one entry, which will remain a submission throughout the duration of the nine-month contest.
Sigma encourages all fans and photographers who enter into the contest to share why they are a Sigma super fan, and photos of what they have shot using their favorite Sigma product on their social channels (Facebook, Twitter or Instagram) using the hashtag #SigmaSuperFan.
