They are mounted between the camera body and the lens， As a rule， the effect becomes stronger the shorter the focal length of the lens in use， and the longer the focal length of the extension ring. Through the-lens exposure control automatically compensates for lens extension. Manual and aperture-priority auto-exposure control modes are possible. Manual focus only.</p><div style="width: 850px; padding-left: 10px; height: 40px; line-height: 40px; border-bottom: solid 5px #00CC00; color: #2B4793; font-size: 35px; font-weight: bold;">About Us</div><p style="width: 820px; padding-left: 20px; padding-right: 20px;">We promise to supply genuine product in Japan.<br />If you have questions please feel free to ask us.</p><div style="width: 850px; padding-left: 10px; height: 40px; line-height: 40px; border-bottom: solid 5px #00CC00; color: #2B4793; font-size: 35px; font-weight: bold;">International Buyers - Please Note:</div><p style="width: 820px; padding-left: 20px; padding-right: 20px;">Import duties， taxes and charges are not included in the item price or shipping charges.These charges are the buyer's responsibility.</p></div></div>
