For FoV but it's not the core of the message here.
Regarding the "2 stops more" I sincerly doubt his numbers are correct.
You let more...

1.6 squared is 2.56. The base 2 log (i.e., stops) of 2.56 is 1.356144.
I round that to 1-1/3 so it translates to camera-based 1/3-stop...

Yes, for total light gathered (light intensity * exposure * sensor size). If aperture and exposure are the same, that's log2(1.6²) =...

The long end of the 100-500, when used on APS-C, gives an FoV equivalent to 800mm on FF, but the f/number remains f/7.1. Thus 800mm...

When using a FF lens on an APS-C sensor, the light intensity on the APS-C sensor is correct for the selected F-Stop. But that extra...

Aren't you mixing up things? Where does 800mm f/7.1 come from here?
Where does that come from? Aperture dictates light intensity...

Yeah, i think making it 100-500 instead of the usual 100-400 was a brilliant idea.

What i want is "cheap" PowerShot with a decent lens with at least 200mm at the long end. Doesn't have to have big sensor, something like...
AlanF replied to the thread Dragonflies and Damselflies.
The dragon hunting season is now in full swing, and the RF 100-500mm is now the stock weapon for me. An Emperor and a rare Norfolk Hawker.
AlanF replied to the thread What’s Coming Next from Canon?.
No, and I use native RF lenses now.
AlanF replied to the thread What’s Coming Next from Canon?.
In terms of signal/noise a 800mm f/7.1 is equivalent to a 500mm f/5.6, ie 0.7 stops faster than than 500mm f/7.1. So, in fact the...

The thing is, if you give the R8II the same sensor as the R6III, the same battery, same EVF and then add a AF joystick…you basically...
