[QUOTE="WayneF, post: 309747, member: 12496"] I have to ask, what is a mega flashing thing? Is it some kind of diffuser for the camera internal flash? Or is it like a LED light on the hot shoe? Or what? Can you provide a link to an ad for one, to see what it is? Reversing ring suggests a close macro distance, only a few inches. Which close distance does not need a lot of light, but stopped down apertures need more. Assuming manual flash mode, what is your typical subject distance, and typical exposure values (ISO, shutter speed, aperture)? Asking... what is it that you are doing? As an example, the bare camera internal flash has a guide number about 40 (feet).. So at ISO 100 and full manual power level, the bare direct flash should do f/40 at one foot, which is a lot of light at one foot. This one foot is measured from the flash, which for macro work, the distance in front of lens is probably about half of that. [/QUOTE]
