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.

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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1149755-sigma-em-140-dg-macro-ring-flash-for-canon-slr](https://www.desertcart.co.uk/products/1149755-sigma-em-140-dg-macro-ring-flash-for-canon-slr) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-27*
