Two Apertures on slr telephoto lens???

Sobalskyk · Dec 10, 2016

I have a vemar telephoto 200mm lens

I am totally, completely new to analog photography

Unlike my other lenses, there are TWO aperture rings on this lens. Both can be adjusted seperateley. Can someone Help explains this. How can I have two different different aperture settings for the same photo? How does that work?

Thank you

I'm not familiar with that lens. But Nikon makes a "DC" lens which seems similar.
It allows you to control the amount of out of focus in the foreground OR background

One aperture.
One ring sets the aperture size.
Other ring is used to open for focus, then you dial down when shooting.

Okay. Can you explain this a little more whenever you find time? I don't quite understand.

For One, which ring is the one I actually want to set for the correct aperture? And what exactly is the point of the other?? I open it up to let more light in so I can see and focus better?? what happens if you take a photo with them at different apertures? Cheers
