Profoto Rectangular Softbox Reviews

From groans to grins

Amazing color consistency out of the lights and this softbox provides a perfect compliment. I was able to set my WB to 6K and forget it. Colors were beautiful. The matched combo made it very easy to do. I also found that - even against my other white softboxes - the reduction in hotspots was huge. As in I didn't have any whereas with other white boxes I tend to have at least small areas. The build quality on these is top notch and the "assembly" (which is really just squeezing a couple of flat sections of the mount together) is almost instantaneous. I struggle with paying this much for softboxes and if you don't shoot a lot I am not sure it is justified, but I am certainly happy I made the leap.

The Profoto Rectangular Softbox (2 x 3', Silver Interior) does not work with the Profoto A10 click system. It has a built in speedring that is made for ProHeads and B10 Lights
