Hi.<br /><br />I am new to the forums today, having just picked up a 180mm SL lens for use with my Nikon FM3a.<br /><br />I haven&#039;t developed anything off the lens yet, so I have nothing to say about images, but the lens is really well built.&nbsp; <br /><br />Now, to the main reason for this post:<br /><br />If I rotate the lens left or right along is axis I can hear a quite distinct sound from inside, from near the mounting end. <br /><br />I&#039;m hoping that this is normal (some sleeve, collar or bearing inside that does in fact rotate). <br /><br />However, before I do any damage I wanted to check with another SL 180 user to see if this is a normal sound for the lens or not, in case there is something loose inside that might cause some damage. <br /><br />Anyway, any feedback would be most appreciated.<br />Yours,<br />Banjo<br /><br /><br /><br /><br />
