For what it might be worth, I too find the Nikon SB-400 to be VERY underpowered!
You would be much better served by using either the SB-600 or the SB-600. Small is nice, but it does not always get the photo that you really want. Sarah Joyce |

My main reason for citing lack of power for the SB400 is related to bouncing. Bouncing significantly reduces your output...you need to throw a lot of light to bounce effectively. Unless you're very close to the subject, your bouncing with the sb400 will be inconsistent at best. Now for general use, such as fill flash, the sb400 should work real well. I still think it's worth spending the extra $50 to $60 for the SB600.

To determine flash range, divide the GN by the aperture. For example, if you're shooting at f/5.6, your flash range would be approximately 12.3 feet at ISO 100 with an SB400: GN of 69 feet / aperture of 5.6 ~= 12.3 feet at ISO 100 (40% further at ISO 200). But, if you're using a diffuser, you will reduce flash range. Ditto if you're bouncing the flash, because you've got to account for travel to and from the ceiling, as well as the diffusion of light you're going to have from bouncing (because it's spread out over a wider angle). It's best to use a more powerful flash for this purpose. You can increase range via ISO speed if needed, to a point. Each time you double the ISO speed, flash range increases by approximately 1.4x. |
