<p>Kari,<br> Will try this many thanks. Real bummer as this lens is otherwise fantastic , even compared to my 55 2.8 micro</p>

<p>Kari,<br> The nose ring has in fact been dented and I am aware of this, however as far as I can tell it is only the filter thread and does not go back further although this my in fact be the problem.<br> As I am wanting access to the focus ring helicals as the focusing is stiff, besides this is there anye other way to access them ? Thanks</p><div></div>

<p>I know thanks , I had a 28 2.0 with the CRC which I had to re-adjust, took a while but it went fine.<br> This is the offending lens</p><div></div>

<p>Just to be absolutely 100% sure,<br /> the only thing keeping it in place are 2 grubs screws 180 degrees apart right ?<br> Thats the case with all my other AIS lenses, just want to make sure there's nothing extra holding it in place before i take a vice to it - carefully<br> Thanks again all</p>

<p>Many thanks for the responses.<br> Im curious what tools people are talking about ? On my 55 2.8 Micro AIS and 28 2.0 AIS , after removing the grub screws i could simple unscrew the filter ring by hand</p>

<p>I cannot unscrew the ring with the lens info on (the front ring)<br> even after removing the 2 grub screws on either side, it is still VERY stuck. any help ? thanks</p>
