I do a lot of macro phography (plants, insects, fine mechanics, but also, recently, more and more medical photography during operations). I have a Nikon D100 (and love it) and my primary lens for this kind of work is the Micro Nikkor 60mm. In the past, I have hired Nikon's SB 29s through Nikon's Professional Services, but as I am doing more and more, I decided it was time to buy my own. Sigma's EM-140 DG is brand new to the market. Nikon's SB 29s has been around for some time and hasn't heard about digital cameras yet. As such, the Sb 29s only functions in manual mode with the D100 (or any other digital). This is okay for some work, but a real pain where you don't have the time to mess about with flash meters (or where you can't get close enough to do good metering because you're working in a sterile area. So... I paid up front for the Sigma EM-140 DG almost two months before it shipped to make sure I got one of the first. It's here. I love it. The LCD screen on the back is not the most intuitive and easy to understand without the handbook (which is the only reason I didn't rate it the full ten points). Apart from that, here is a brief overview: - The flash (like Nikon's) isn't actually a ring flash. It has a flash on each side of the ring (so a total of two). Where Nikon has added a sliding milky cover that you can rotate to cover one side or the other to regulate the intensity of light coming from one tube relative to the other (to introduce light shadow to combat the "flat" look of photos typically produced by ring flashes used alone), Sigma allows you to indepentently (electronically) regulate the intensity of each tube 1/1 (full power), 1/2, 1/4, 1/8, 1/16, 1/32 and 1/64. Or to turn a tube off entirely, of course. This is a wonderful feature. Like Nikon's version, the Sigma also has a lamp function to assist AF in dark conditions (weak light, but - hey - this equipment is designed to work up close). But the graetest and most obvious feasture is that is works fine with the Nikon D100. This is omportant to know because when you research it on the web, it is immedately obvious that it works with Nikon's i-TTL (as seen in the D70 or D2 series), but it is unclear (it is suggested in footnotes, but not obvious) that it works with the older D-TTL (as seen in the D100 and D1 series). It does. And it does a very fine job, too. No hassle. Powerful. Very versatile, snap-on, snap-off. I get good effects (where I want shadow) by just unhooking the ring element from the lens and holding it to cast sidelights on the object. Click. 3-D emphasis! I love this flash and hardly need to recommend it to any serious macro photographer with a digital SLR. As far as I can tell, there is no real alternative out there, except for the (significantly more expensive and with less functionality) Nikon SB 29s. Having said that, I am sure Nikon will provide a newer version of the SB 29s, and then it will be - as always - a product worth looking at. But for now - no contest. Sigma EM 140 DG wins hands down.
