I chose this model over the MT-14 because I liked the ability to set the flash positions independently, giving you maximum control over the final image. I found it very easy to use and felt comfortable straight away, although I don't actually use flash, I prefer natural light. However, macro photography often requires extra light, which is why I was pleased to find one that's so easy to use. Just a warning if you have a 100mm with IS you will need to buy an adapter ring to make it work. It's annoying but doesn't interfere with the flash as it was released before the 2nd gen 100mm macro.
