Here's how to zoom in Minecraft on PC.
With no mods, your ability to zoom in Minecraft
is limited to the FOV setting,
which changes how wide or narrow
your character's point of view is.
In the pause menu, click "Options"
and you'll see the FOV slider on top.
By default, it will be set to normal,
which is numerically set to 70.
By bringing the FOV to 30,
your point of view will become
much narrower and zoomed in,
letting you see further
but with minimal peripheral view.
You can see the opposite effect
by widening the FOV to a higher number,
which lets you see much more to your left and right
but makes the distant objects feel even further.
For a more streamlined ability to zoom in-game,
you'll need to download a mod.
For Java edition, the mod OptiFine
is hosted on Optifine.net,
where you can find the latest release
under "Downloads."
Make sure you download a version
that matches your Minecraft version.
If you don't have it already,
you may need to install Java SE to open the mod.
Go to the download page on the Oracle site
to grab the latest version and install it on your computer.
With Java installed,
go to your OptiFine file and open with Java.
The installer will walk you through a few simple prompts.
Once finished, you'll be prompted to click "OK,"
which will install OptiFine as a module in the game.
Start the Minecraft launcher,
and on the bottom left, confirm OptiFine appears
or is selected where it says latest release.
Now in-game, you can confirm your zoom mod is installed
by pressing and holding the C key
to zoom in and out with a simple press.
If you'd like to change that hotkey,
navigate in the game menu to "Options,"
"Controls,"
then scroll to the bottom to the miscellaneous section.
Here, you'll find an entry for zoom.
From here, you can select whichever key you prefer
to utilize the OptiFine functionality in-game.
If you're running Bedrock,
your mod options are smaller.
A recent release called Windows 10 FOV Changer on GitHub
will do the trick.
Scroll down on the page to click the direct-download link
and open the zip file.
Once unpacked, you may get an error
opening the FOV Changer application.
This is because it only works
if Minecraft Bedrock is already launched.
With Bedrock open, relaunch the FOV Changer app.
On the left, you should see a start button,
and clicking that will produce a series
of green check marks to confirm it's running.
With your Minecraft world loaded,
pressing the V key by default
will activate the FOV Changer function.
To change that hotkey,
go into the FOV Changer application
and adjust the button under "Features."
