I was looking forward to giving this lens a try and it didn't disappoint in most areas including image quality.
The early popularity of this lens has kept it out of stock at most retailers. B&H has just received a shipment of the Tamron 15-30mm f/2.8 Di VC USD Lens and is showing in stock at the moment. I doubt that this stock will last very long – don't wait to order if you want this lens.
Other in stock options: At least one lens is available at Amazon and several are available on eBay right now.
GRAND RAPIDS, Mich. – March 24, 2015 – X-Rite Incorporated, a global leader in color science and technology, and its subsidiary Pantone LLC, today announce an important update to its popular i1iSis Solutions family of automated chart readers for prepress/premedia, photo and pressroom color management and profiling. The new i1iSis 2 and i1iSis 2 XL use i1 spectral technology to accommodate M0, M1 and M2 measurement illumination conditions which help manage the complexities of measuring optically brightened substrates now commonly used in grand format, premedia and digital press applications.
“For anyone in prepress, digital print or the graphic arts production process that spend time measuring charts, the new i1iSis2 is a must,” said Ray Cheydleur, Printing and Imaging Portfolio Manager of X-Rite. “This automated chart reader, is built on our award-winning i1 spectral technology and reads up to 2,500 patches printed on a single A3 page in just minutes, saving valuable operator and production time. Now users have the ability to capture M0, M1 and M2 in a single chart measurement cycle.”
The i1iSis 2 integrates seamlessly into a user’s workflow and is available in two models:
i1iSis 2 XL: Reads up to 2,500 patches on a single A3/Tabloid sheet in just 10 minutes.
i1iSis 2: Reads up to 1,500 patches on a single A4/Letter sheet in just 8 minutes.
The X-Rite i1iSis 2 and i1iSis 2 XL come with built-in vision systems that offer high tolerance for how charts are aligned as they are fed into the system, automatically correcting for misalignment. Barcode reading for chart identification adds further ease of use and error reduction.
With the i1iSis 2 and i1iSis 2 XL, users are able to:
Capture full spectral data for the charts they measure;
Use with i1Profiler software to accommodate a variety of inks and substrates in any viewing condition using Optical Brightening Compensation (OBC);
Assure compliance with new ISO standards for M-Series measurement illumination conditions; and
Spend less time on press profiling and more on taking care of customers.
The i1iSis 2 and i1iSis 2 XL are XRGA compliant. The X-Rite Graphic Arts Standard (XRGA), an X-Rite calibration standard for graphic arts instruments, includes new advances in color technology and changes required to meet ISO-13655. As XRGA-compliant instruments, the i1iSis 2 and i1iSis 2 XL ensure high quality data exchange and workflows in environments where different instrumentation is used.
Note: I realize this is a second generation product, but I can't help thinking X-rite missed a good opportunity to change the product's name from "iSis" to something less relevant on today's political landscape. [Sean]

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.
"ZEISS has been producing camera lenses for more than a century – and the tradition of creating major innovations has continued to this very day. For example, the current ZEISS Otus SLR lenses are setting new standards in image quality. The first camera lenses left the Jena production facility on 21 March 1890."
