Nothing has changed

I've added a separate calculation for ADS now.

I was hoping they would drop these nauseatingly awful zoom levels down to BF4 levels with this update 😕 these iron sight zooms should be a crime punishable by death

The best way would be to convert directly from your BF4 aim to your BF2042 aim using 360 distance, like in this example (with just example values):

in my testing, setting scopes to match hipfire sense 'works', but it'll feel wrong for most engagements.  if you come from games where you didn't need ADS or ADS could be run at 1x, you are SOL in this game.  probably most of the older gamers.  if you are used to magnification, your options are:  have it 'feel' the same to your eyes, but your in/360 at the zoom level will be wrong and you'll snap to a target too slowly based on muscle memory.  Or set the scope to the same in/360 as the previous game's in/360 with the same magnification or your hipfire's in/360, but it'll feel wrong to your eyes. 
there's not really a winning scenario for anybody unless the devs bring scope zooms back to parity with other games AND add 1x optics. 
it also doesn't help that in the 'future', all the guns are just worse.  i'd think based on materials and munitions science, ALL the guns in the 'future' should be laser beams.  instead, we're practically firing muskets (NTW-30) and the fact that player engagements are basically double the distance they were before, which you need laserbeams for to be viable on the ground.
Then, you look at vehicle combat and the turrets are accurate at hipfire sense, so a little muscle memory shreds players on the ground.  I guess they could make the vehicle turrets totally inaccurate unless in ADS as well, but that's the last bastion of accuracy in this game unless optics are fixed AND they add 1x 😕

i wish this game had 1x optics. 😕 this 1.25/1.71x as minimum stuff is killing me.  it scares me there might be a zoom added to optics when they presumably roll bf4 into portal someday.
Thanks for all the work you do @DPI Wizard !

Here's a full comparison between BFV and BF 2042 scopes (10x missing on BF2042, working on it!). These are the base values showing the true optical zoom, those under 3.00x will be affected by ADS FOV on/off.
BFV are using the actual optical zoom for the scopes.
BF 2042 uses seemingly arbitrarily assigned values, but they almost line up on a linear axis.
Scope Zoom BFV Zoom BF 2042 1.25 1.250 1.710 1.50 1.500 1.997 2.00 2.000 2.586 2.50 2.500 3.188 3.00 3.000 3.793 3.50 3.500 4.405 4.00 4.000 5.016 5.00 5.000   6.00 6.000 7.482 7.00   8.711 8.00 8.000 9.950 10.00 10.000 12.420 12.00   14.907 Edit: 10X scope added!

Yeah, I think it throws a lot of people off, as they assume the 1.25x is the same as in BF1/BFV. But since it's quite a bit more powerful it feels completely different, and is too powerful as the minimum zoom.
