<p>Hi guys, I am quite new to Hasselblad and bought a Heliopan B60 filter for my Carl Zeiss 80mm CFE lens. However, the filter seems to be to small. The lens cap writes: Ø60, but actually its diameter is about 70mm. The filter writes: B60 and its diameter is 60mm. Did I buy the wrong filter? Or it is just that I don't know how to mount it?<br> Thank you very much for your kind help!<br> <img src="http://i.imgur.com/WV9cGYp.jpg" alt="" width="960" height="1280" /></p> <p><img src="http://i.imgur.com/CtkXUvv.jpg" alt="" width="960" height="1280" /></p> <p><img src="http://i.imgur.com/VzXH2dN.jpg" alt="" width="960" height="1280" /></p> <p><img src="http://i.imgur.com/qaHNiYu.jpg" alt="" width="960" height="1280" /></p> <p><img src="http://i.imgur.com/rVp4QoI.jpg" alt="" width="960" height="1280" /></p>
