I’m not an expert in creating mods and much less in Quilt. Considering that it is a Fork of Fabric, and the documentation on the Quilt Wiki is not complete, I’m sure I mixed some things and didn’t use others that Quilt provides to make life easier BUT, it works, it serves, and I’m happy.
How to Use
How to Install

Dependencias
Quilt Loader: Quilt.org
Quilted Fabric API (QFAPI) and Quilt Standard Librarires (QSL): Modrinth
Quilted Fabric API (QFAPI) and Quilt Standard Librarires (QSL): CurseForge
How to use the mod
The default key for the mod is “Z”. You can reassign it to another key in Options > Controls > Keybinds…
Scroll Zoom
You can increase and decrease up to 4 levels of Zoom with the mouse scroll.
Commands
/lagzoom setCinematicCamera true
This command is to activate or deactivate the cinematic camera of Minecraft. (true, false)/lagzoom setZoom 10
It is the percentage to use in the Zoom. (min:10 - max:80)
Note: It is a percentage of your current FOV
Example: setZoom = 10 would be YOUR_FOV(100) * 0.10 giving a total of 10 FOV. That is, when zooming it will be as if you had 10 FOV, which is basically the Zoom, increasing your FOV.
/lagzoom setZoomLevelAccordingToScroll true
This command is to activate or deactivate that your default Zoom is the value you left with the Scroll. (true, false)
Credits
@NicoIsLost - Zoom-o-Matic - Who inspired me a long time ago to learn to make my own zoom (although I left it xd) currently I learned to make the commands with his repo and also inspired to make this mod to also teach other people, but totally in Spanish.
@LogicalGeekBoy - LogicalZoom - From whom I took code (The one I titled GameRendererMixin) to know how to modify the FOV, mention that his mod is quite simple and very “easy to learn” so I urge you to read it.
@DoctorR4t - Thanks to his videos I took seriously and resumed learning to make mods. It is because of him that I used Quilt and not Fabric.

Server lagging with Lag-Zoom – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Lag-Zoom consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
