What does yds in the scope mean?

It is a unit of measurement. These should be for your camera.

It is best to go to the photography forum to find out what performance parameters different numbers represent. It will be of great help not only in terms of hardware, but also in technology!

mm is millimeter

Wide angle is what cameras often call "wide angle"

ft: it is feet, feet (foot, abbreviated as ft. Equivalent to 12 inches, 1/3 yard, 0.3048m)

yds: yard. Unit of length

1 yard (yd) = 0.9144 meters (m) 1 foot (ft) = 12 inches (in) 1 yard (yd) = 3 feet (ft)

Hope this helps!
