I'm a serious photo student about to invest in my first set of studio lights. I want a powerpack and strobe setup, and a high quality system that I can build on for many years. I'm considering the Profoto Acute2R 2400, the Norman D24(w/ pocket wizard built-in), or the Calumet Elite 2 2400. I'm also open to other suggestions. What I do: I like product photography and want to pursue it as a career. I've been taking senior portraits at a studio for 1.5 years. I shoot with a Sinar F1 4x5 camera, a Mamiya RB67, and a Nikon D200 digital. I consider myself very technical and tend to try to push the technical envelope much farther than the artistic one. I don't doubt that I'd use all 2400 w/s of any of these powerpacks. I'd also like to use this studio setup for taking portraits. I know most of the specs pretty well (except for with the Calumet). Power is equal, the Profoto has only 3 head outlets, while the others have 4, the profoto has a slower flash duration (1/320th) at max power than the Norman (1/800th). The calumet doesn't have a built in pocketwizard. I do want wireless control, fussing with sync cords in front of clients is embarassing. Recycle times are all with in 1/3 second, the Calumet doesn't have a switch on its optical slave, and it's also the heaviest. Student discount prices put the Profoto w/ 2 heads at $2650, the Norman at $2465, and the Calumet at $2450 + the cost of a pocketwizard transceiver. Accessories will be much more expensive for the profoto, but higher quality. Also the Profoto has less convenient power adjustment, but is also 5-8 pounds lighter than the competition. I do place some value on portability. What I don't know and what I would like to hear, are some testimonials from people with experience with these. I've worked with the Profoto packs, and lower quality Normans(808, P500s, etc.). The Profoto seems to be the ultimate quality, with great engineering like the zoom reflectors. Everything is solid and well built, and feels top-notch. The other two seem to be more value-based. They have 4 head outlets, more finely adjustable power(the Norman atleast), faster flash durations, etc. More features, but not as top notch basically. I doubt I'll ever need the adjustable voltage of the Prototo (for other countries right?), or the precise color accuracy. But yet I do long for the absolute quality. I love my D200 not for its obvious feature over the D70, but for the hundreds of tiny things that I noticed after buying it. I guess I don't ever want to feel limited by my equipment, and when buying equipment I want to do things right the first time. But I'm also trying to develop good business skills, which means not indulging in the nicest most expensive equipment if I can do just as well with something cheaper. So let me know, was your Profoto setup worth every penny, or are you happy you wen't a more economical route?
