In reply to Sackramento:

No, you need to prehook the zoom functions with a script or addon

Blizzard did not provide any command or CVar we could use

local increment = 4 -- default is 1
local oldZoomIn = CameraZoomIn
local oldZoomOut = CameraZoomOut

function CameraZoomIn(v)
	oldZoomIn(increment)
end

function CameraZoomOut(v)
	oldZoomOut(increment)
end

Poll: What is the best max distance http://www.strawpoll.me/14091428

Are you satisfied with the current 39 yards distance or do you miss the old 50 yards distance?

Are you using DynamicCam?

MaxCam won't load if that addon is loaded, since DynamicCam has the same features and more

Ow, MaxCam indeed also won't work if FasterCamera is loaded since they are basically the same addon

The 50 to 1000 yards camera distance was only possible for one week in August 2016 if you read the reddit thread, now it's limited to 39 yards like any other addon

I did post those screenshots below but they were for nostalgic purposes and only taken during that time

There were no camera changes for this minor patch so there is no need for an update

Updated for 7.1 now, happy scrolling 

In patch 7.1 the default UI slider has been removed and the cvar renamed to cameraDistanceMaxZoomFactor
