I find it is not possible to access the choice of FOV (Dewarp/Wide/Superwide) when we are in HB mode. Have to come back to RS to be able to change FOV... Bug?
I noticed FOV in HB is the same in all FOV modes, but it should not be a reason to forbid the change of FOV modes.
Example, if I want to change from Wide HB to Superwide RS, I cannot change FOV first and then IES, I have to change IES first and then FOV mode...

Hi Yaman-Python, Horizonbalancing FOV is equivalent to 17mm.
wide (fisheye) looks very similar to standard ( linear) when FOV is > 15mm, the distortion makes slightly change.

that's why HB and HS only have Dewarp.

Thanks. I  see. What is funny is that while in Superwide for example, I can still change EIS to HB, which is not allowed in that FOV mode, but the software accepts that request and changes the FOV to Dewarp. It may be viewed as a shortcut to change 2 things (FOV mode and EIS) in one operation. Not bad after all. Just confusing at first.
