EM-140 DG Macro Flash
Capture Every Up-Close Detail
The Sigma EM-140 DG Macro Flash is ideal for photographing subjects in fine detail and is extremely effective for scientific and medical applications. Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates modeling, which can give a three-dimensional feeling to the subject. The flash features a guide number of 14 w/ISO 100. The Modeling Flash function makes it possible to check for reflections and shadows before actually taking the flash picture. A wireless flash function is also available, where the EM-140 DG is used as master and the EF-500 DG SUPER as a slave unit for creating fine shadow details. 55mm and 62mm adapter rings are included with the flash. 52mm, 62mm, 67mm, 72mm and 77mm adapters are sold separately.

I compared the ring flash and lens with the ones offered by Canon and felt that it was worth saving $300 by purchasing the Sigma combo.
The macro lens/ring flash work well for dental purposes. After a little experimentation I discovered that I get the best images by using the aperature priority setting. All settings are used with ISO 400 speed. I set the aperature at 14-16 for intraoral shots. This gives the best depth of field. I also use the operatory light for intraoral shots. I set the aperature to 6 for full face shots.
I use autofocus but set the ratio to 1:2 to 1:3 for intraoral shots. This keeps the autofocus from "hunting". I frame the shot by moving towards the subject. Once I get close to the image that I like I use the autofocus to get the final focus for the picture.
Anyone involved with flash photography knows the vale of ring lights not only in macro photography, but also portrait work. Simply put, it is a great tool with "vertical" (limited) application in the general photography context. Sure, you could use a regular flash gun, or two. However, the effect is simply not the same and actually harder to achieve using multiple flash guns. And, for those choosing between this unit and the much cheaper continuous lighting units (i.e. Neewer), there is no comparison. This is a pro tool. I tried the other units with dismal results. A 48 LED unit is simply unusable in portrait work, it blinds your subjects! I know, I tried it with my wife and she nearly fell over. But, if you are just taking photos of objects, they work pretty good with some tinkering and chimping.
The unit seems well constructed despite the plastic shoe. The unit takes 4 AA batteries. The battery door seems a little weak, similar to many other flashes (common problem even with Nikons). As I am not a combat photographer, I expect the uniot will hold up well for my use. Sigma includes a decent packing/carrying case you can use since this item is too bulky for your bag. Interestingly enough, there are no attachment loops on the bag for you to attach it to a camera bag (I am a big user of the Lowepro sliplock attachments and system). A big issue I have with Sigma is the limited attachment rings they provide (they call them macro/flash adapter). Specifically, they only give you two; a 55mm and 58mm. I mean seriously, what were they thinking? They should have included a few more sizes for sure. Expect to spend about another $40 on additional adapters for your lenses. The adapters screw onto the end of your lens and the flash unit snaps onto it, providing a very suitable platform.
The unit worked right out of the box with a Nikon D300s and a Nikon 50mm 1.4 G lens. I used 4 Duracell coppertops in the unit. The unit is not entirely intuitive to use, so you will need to look through the manual, which says just enough to get you going. There appears to be a learning curve in the TTL use of the EM-140. For example, choosing a faster shutter and smaller aperture shoot reduce exposure. In nearly all my tests, it does the opposite. Very weird. Of course, I have only had the unit about three hours and still learning it. May have something to do with the way Amazon packed it as well. I would be interested to know if anyone else experienced similar exposure results on a first run. However, when testing on my wife, when the exposure did lock, results were incredible. Once again, the anomalies may have more to do with me or the packing than the unit itself. I did however determine that spot metering provides the absolute best results in both macro and portrait work. This think will kick butt when you custom white balance in spot metering mode.
I plan on editing this review after sustained use.
EDIT 9/17/11: Notwithstanding the other reviewers who gave this flash a good to great rating, I found the opposite. However, it is likely my product was damaged in shipping as Amazon seems to provide better packing for toothbrushes than expensive photography gear. In my case, the EM-140 never seems to get the exposure right (TTL). Plain and simple. It did not work. In manual mode, I can get it to work. Even then though, I find it's use limited to Macro work (what it was designed for) and not even the least bit helpful with portrait work. But like I said, it does not seem to work in TTL. I tried everything. Unfortunately, I am sending it back.
"Ring Flash" is a bit of a misnomer - it does not have a circular flash tube, it has two flash tubes, one on either side of the lens. You can shoot with both tubes, or select one tube. Built in modeling lamp is a nice feature. This Sigma unit is a worthy successor to the Nikon SB-29 & 29s. It's well designed & well built. Controls are clearly laid out and the TTL feature works very well. Thanks to Sigma for continuing to make this rather specialized flash. While there isn't a huge market for it, when you need this type of flash, nothing else will do.
I've used this for macro photography and...it...is...amazing. Allows me to not worry about lighting issues and close my aperture and still get great images. easy to use. If you are looking for a macro flash I would get this. Much better than the dual flashes as it eliminates ANY possibilities of shadows.
However, I was very disappointed to learn that the EM-140 does not work with all Canon cameras that are compatible with the equivalent Canon ring flashes. The Sigma tech support was very prompt in answering my query regarding my G15 (which is a wonderful camera). The response from Sigma indicated that the EM-140 "is not compatible with the Canon G15 or any other mirror less camera, it will not work correctly for you on your camera." So there you go.
The symptoms are a series of rapid pre-flashes followed by a very dull flash when the shutter fires about 1 second after the button is pressed. The sequence is similar to a red-eye preflash, but that feature as disabled on the camera. The camera and flash are clearly having a "failure to communicate."
I tried to use manual mode on the camera, but the flash goes to ETTL mode even after being set to manual. The flash buttons are disabled, the unit acts as if it's dead. But it does flash (as described above) when the shutter is fired. If I put the camera into manual after powering the flash I can get the flash buttons to work, and can put it in manual, but it still misfires.
I wonder if the EM-140 will also be incompatible with future Canon cameras. I suppose this is a risk we take when going off brand. I won't make that mistake again.
