<p>So yea, the not sure which is which but on the left side, the outer knob stops turning when it reaches till like the middle between 10 and 25. The second layer just doesn't even turn... Can someone help me? Or does the aperture and the ISO not matter on a RF camera? Thanks!! <img title="Smile :smile:" src="http://www.apug.org/forum/styles/apug/smilies/smile.png" alt=":smile:" /></p>
