What F/Stop is 1:2 lens?

Bidding for a lens with F 1:2

Is it 1.2? Or doesn't it mean something else.

it's a nikkor 50mm 1:2, i want a nikkor 50mm 1.2

Al lens with a 1:2 notation is an f/2 lens.

If the lens was an f/1.2 lens, it would say 1:1.2

It is one of those 'manual focus' lens. And it is F/1.2. The sharpest lens made by nikon so far.

I don't know what planet "tatya" is from, but I just gave him / her another well deserved thumbs down for that totally wrong answer.

Yes, it is an f2 lens. On lens specs, aperture and aperture ranges will be preceded by 1

Definitely an f2 lens. Tatya is an @rse.

1:2 is f/2.

1.2 would be 1:1.2
