I just got my Sigma EM-140 DG Ringflash and a set of Kelko extension rings to play around with macro photography.

I started out with just the large 36mm extension ring. As this was my first foray into extension rings I was quite surprised at how close I needed to get with just the 36mm ring on my Canon EF-S USM 85mm 1.8. That lens useually manages to annoy me sometimes because you have to be so far back to focus on anything. Not so now, I need to be about 10cm tops to focus.

I quickly learned that auto focus is right out hehe. The area of focus is so shallow that even breathing is enough to blurr the area you want to focus on, good thing I started out with just the 36mm and not the whole set.

The Sigma EM-140 DG Ringflash works amazingly well, no harsh shadows as you’d normally get with on camera flash. The great thing about the Sigma EM-140 DG Ringflash is that it will trigger my other EF DG-500 Super flash wireless, haven’t played with that yet though.
