Best of the Single Speed Light Soft Boxes
on January 5, 2014
I own the Westcott 26" Octa Rapid Box (w/beauty dish attachment) as well as the Interfit Strobies Rapida 18" soft box. I purchased the SMDV Diffuser 60 because the Westcott ate over a full stop of light from my speed light and the Interfit has a hot spot in the center of the pattern due to a lack of an inner diffuser. Not only does the SMDV produce a softer and more even quality of light, it is also more efficient than the other two modifiers. My test showed that the SMDV Diffuser 60 only decreased the output of my Nikon SB-700 by 1/3 stop, which is even better performance than the smaller Interfit Rapida. The SMDV has a deeper profile than the Westcott or the Interfit. My guess is it must be closer to a parabolic shape which helps with the increased light output.
It has been well documented in these reviews about the build quality. Yes, the mount is plastic, but the entire unit is very light in weight and sturdy enough if it is not abused. I think the trade-off in materials is offset by the design, which allows for really fast setup and tear down.
The SMDV Diffuser is more expensive than the other units that are based on this design, but it works better for my uses. I plan to purchase another unit soon.
