Ok, so after 2 years of playing with my camera and taking a few classes, I decided the area of photography that I would like to focus on. I would like to build a business around labor and delivery, and newborn photography. With this selection comes crappy lighting, fast action and non-repeatable moments and usually crappy vantage points....fun fun. So My question is about lenses and flash. I do not wish to be changing out my lens often, so what 'do it all' lens would you use...keep in mind, it needs to be kinda fast in crap light... Also, for the slower paced newborn photography I am looking into a softbox, but I am not sure I understand how it works...Is it a separate flash inside the softbox that is triggered by the camera? What all do I need to make that work? Thanks in advance!
