## Description

From the Manufacturer               The Electronic Flash Macro Ring EM-140 DG is designed to work with both AF 35mm film and digital SLR cameras of all popular manufactures. It is ideal for photographing subjects in fine detail when the shadowless mode is used and is extremely effective for scientific and medical applications. Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates shadow, which can give a three-dimensional feeling to the subject. The flash features a guide number of 14 with 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 when the EM-140 DG is used as master and the EF-500 DG Super as a slave unit for creating fine shadow details. High-speed synchro and exposure compensation functions are also available for advanced flash photography.

## Questions & Answers

**Q: can I take video using this Macro Flash with a Nikon camera?**
A: I have not used the flash for video, but for my experience using it you're not gonna get much of long range.

**Q: Does this flash works with 85mm lens ?!**
A: As long as the filter ring on your lens is either 55mm or 62mm, those are the sizes of the two adapters that come with the ring flash.

**Q: Will it work for Sony Alpha 55 ?**
A: Depends on the lens that you plan to use - the flash comes with 2 adapter rings that screw into the front of your lens, they are 55mm & 58mm. If your lens is one of these sizes, it will work.

**Q: Is it compatible with Nikon D90 ?**
A: Yes it's compatible. I've used it in a D300 ,d700 . The mounts are the same and all the different lens adaptors are the same based on lens diameter. Doesn't get much simpler. Some newer Macro kits  are cheaper and do  a good job but I've depended on the sigma for years and the quality is excellent.
