Hello, my dear friends. Some of you might read that I was asking some advice on the camera setup for dental clinic. I'd like to ask you if anybody used both Canon MR-14EX (original version) and Canon MR-14EX II macro ring lite flashes? Are there any differences specifically for my use in the clinic with the controlled and ambient light? Unfortunately, reviews on Amazon/B&H are very scarce, and I don't want to part with $500 buying a wrong item. Thank you all in advance!
