ok i got a camera and on the lens, and im a bit confused about what the numbers on the lens means, i have an idea but i want to make sure

so could someone please explain what each row means
and if possible how i go about removing the lens



i know that the one ring of numbers that are green/white means the distance of focus

but what does the second and third ring mean

Looks like the 2nd and 3rd ring are your aperture rings. Used to set well, the aperture

well the second ring form what i know is immovable

ah ok. The second ring might have something to do with your focus distance. I'm not too great with older lenses. What kind of lens is it?

The second ring is basically used to lock in your aperture so you can use it on an automatic setting... Thats what those orange dots are about.

so if i line up the numbers on the second ring to the third to get a correct focus?
and this is a 35mm film thats 100% manual
its a pentax k100 if you didnt notice
so how do i go about using those indicators, i know what apeture does, but im not sure on how this stuff affects it

Than I have no fucking clue. With all my Nikkor lenses thats what those are.

i know the numbers are what those are for, but how do i use them?

You don't. That bottom ring is your aperture ring. All you do with that is turn it and select your aperture.

so then what does the middle ring stand for?
