Selling FD Lenses

Hello reader, this is my first guide ever. This guide is about how to open the aperture blades to the lowest f/stop to show off the lens. When the aperture is fully open, the pictures of the product look more enticing. It looks particularly sexy on a 50mm 1.2 (which I will never be able to afford)There are two "buttons" that need to be pushed down the the lens, shown here. First push down the one closest to the red dot, then the next. (If you can't get the buttons to stay down, simply turn the inner ring clockwise while pushing the buttons, not much pressure is needed.)After both are down, rotate the inner black circle gripping the two black nobs.The lens should make a clicking sound and the apeture should be wide open.To return the lens to normal, simply click the silver button on the side of the lens and rotate the black inner ring counter-clockwise.
