Aperture Priority vs Flexible Priority.

The manual says about Fv; "In this mode, you can set shutter speed, aperture value, and ISO speed manually or automatically and combine these settings with your choice of exposure compensation.".

I want to understand this more so has anyone got any real-life examples where they've preferred using Fv over Av ... and why?

Air Shows.

I want a shutter speed of 1/250 or slower for decent prop blur, aperture f8 as the sweet point of the lens, auto ISO as the exposure can vary dramatically as you pan with the plane across the sky, an exposure compensation as the subject, the plane, can be heavily backlit.

I used to use manual on the 7D2 but there can be just too much light for 1/250, f8 at ISO 100. So adjustment is needed 😬

It’s quite quick as one dial switches the item to adjust, while another adjusts it. Like cranking the shutter speed up for jets. I quite liked it when I tried it at my first R5 air-show.

Most other times I shoot in AV, in the ISO Shutter setting, I crank that up to +1 when using the 100-500 with 1.4x or 2x adapter, or tye 600 f11.

FV is a new way of working and offers some advantages in certain shooting situations.

I wondered why the ball kept getting bigger, then it hit me.
