Profoto RFi Octa Softbox Reviews

Perfect

Rated 5 out of 5

Perfect key light for individual portraits with soft fall off. Versatile to use on larger set as an accent light, or with a grid, purchased separately.

Great Light

By Michael
Rated 5 out of 5
Date: 2022-06-14

Profoto has the reputation of being expensive, but giving great light. This softbox is no exception. I love the quality of light I get from it. Other reviews have called it poorly designed, being hard to put together and take down. I don't think the criticisms are fair. It's just a question of technique and practice. I suspect some people are trying to assemble the rods in the wrong order. It's necessary to assemble rods opposite to each other (3 o'clock position then 9 o'clock, etc.). If someone is trying to insert rods next to each other around the periphery, they will likely fail. On disassembly, the rods will be under tension. If you pull up on the rods as you take them out, it will reduce the tension and be much easier to accomplish. The quality of light from this softbox is worth the effort.

Should I get this even though I already have the 5' Octa?
Asked by: Jaime
It would depend on what other boxes you already owned and if you specifically needed it. If you own only the 5' then it would be too similar. If you own a wide variety and just need it for a specific purpose then go for it.

question

Will the older Profotl speedrings for the RF boxes work with this?
Asked by: David G.
Due to the new design and different rod diameter of the rods included with the Profoto RFi softboxes, you must use a Profoto RFi speedring with a Profoto RFi softbox. Other speedrings will not be compatible with this softbox.
