7D onboard flash dimesions?
- Thread starter pmerc
- Start date
You can read the 7D manual on Canon's website. P112 is the flash distance table.
ISO400 F/3.5 is 23ft
ISO400 F/4 is 20ft
ISO400 F/5.6 is 15ft
Also, the flash range drops to only 6ft @ISO400 when in "wireless" mode because half the energy is consumed in the 30-50 pre-flashes that communicate exposure info to the remote flashes. It would have been a far superior wireless system had they gone the "radio" route. A simple 5" wire (removable plug-in) would have accomplished this. The wire would be the antenna.

sorry I should clarify,
Phycial measurement of onboard flash
1 inch x 0.25 inch for example

I thought you wanted specs as it is odd to ask for dimensions. I just figured English was your 2nd language. Sorry....
My flash is approx 1.75 wide and 2.00 long. Approx, I didn't actually measure it.

thanks for the help!
and in mm, perfect!
Dimension Definition=
1. A measure of spatial extent, especially width, height, or length.
2. Extent or magnitude; scope. Often used in the plural: a problem of alarming dimensions.
So I guess both interpretations are correct.
I appreciate you both taking the time to answer my forum question.

P.S. I checked my first message too and did notice a typo "that" vs "what" so my bad on the typing skills. Thanks again!

Hopefully the author of the pic I pulled from google images will not mind my alterations.
I was referring to the pop-up flash unit and the width x height of the white plastic flash unit.

I was thinking he wanted the flashtube housing so they could possibly fit a diffuser over the entire thing. Only the OP knows what he's asking maybe we will hear from them.
sorry I rushed to judgement on what I perceived their question to be. I think I'm correct though.
