Query: Lightweight and works great!

This Omnibounce diffuser is a must-have for indoor shooting, especially when you have walls and ceilings to bounce off of. With this diffuser, some light will be directed toward the subject to fill the face or the shadow under the eyes. It will eat up your Flash power a little but it has never been a problem with me because I am not a professional photographer who shoots like 500 shots in one evening. If that's the case, just carry some spare batteries and you'll be set. I also find it useful outdoor when the subject is under some shade, not in direct sunlight. Last but not least, it's super lightweight and fits my 430EX II perfectly.
