This alternate version of the original Sony PXW-FS7 and PXW-FX9 viewfinder rod provides an additional 3 full inches (76mm) of length to allow a greater range of adjustment of the viewfinder to 9 inches (228mm).
This replacement solves a common problem of not being able to move the viewfinder further away from the eye.
9 inches length. Black Anodized 6061 Aluminum
The original Sony viewfinder arm is 6 inches in length
Note: The original rod by Sony is proprietary. Because of this, this replacement rod is slightly different from the original. The corners have been milled off just right to make a very snug fit - essentially duplicating the fit of the original Sony part.
