<p>Last update:<br> Hi all, <br> I just received my lens this morning and ,wow, it works like it supposes to.<br> Canon has replace the PCB Assy, Gyro (part#YG2-2880-000.<br> I'm a happy guy now.</p>

<p>Obviously they did not do a field test in my case but... everybody makes a mistake ! And they did apology.</p>

<p>Update about my lens :<br> I received a phone call this morning from Canon Canada telling me that my lens is ready to be sent back to me .<br> The technician told me that he replaced the IS the third time but the IS still does not work ! Finally he found out that the pivot/axis (?) is damaged . He said that this is the first time he encounters this problem. I hope the lens must be good after the repair.</p>

<p>Hi all,<br> After submitting the pictures taken with my 100-400 IS lens, I got a phone call from a customer service representative from Canon Canada. He wants me to send the lens back (attention) to him so he can personally test the lens before the technician do the repair . Hope they will test the lens after .<br /> The lens is now en route to Canon Canada Service Centre in Toronto .<br> Will keep you update with the result.</p>

<p>Updating my post :<br> Hi all,<br> I did take test shots again and realize that the IS of my lens is not effective so I phone Canon to discuss the problem. They want me to send them test shots (unprocessed) so they can decide if the problem is real and if I need to send the lens to be repaired again.<br> I'm waiting for their answer and will keep you all updated.</p>

<p>Hi Peter,<br> I did try take some pictures with the IS on and off and see almost no difference when checking the sharpness of these pictures . That why I sent mine in the first place after I tried the one from a friend of mine and saw a clear and effective stabilization of that IS system.<br /> I described to Canon the "problem" (I thought) when sending mine to be repaired and assume that Canon will check their work before sending it back to me , but twice, I see no difference . Still confused !</p>

<p>Hi Mark,<br> Look at this link: http://www.kenrockwell.com/canon/date-codes.htm</p>

<p>Hi Mark,<br> Your lens is made in 2013. I did send mine to fix as I said in my post but ... I think it came back the same. Who has the same old lens as mine (2001) please give me some idea . Thanks.</p>

<p>Hi Jamie,<br> To be exact, they charged me $319.00 for<strong> out of warranty standard labour charge</strong> (paid in advance) . They could charge more if the problem is more serious and needs more parts . At the end I did pay $368.48 (include tax and shipping). For service details (from Canon), it says : Replaced listed parts, adjusted to spec .<br> Part description : - One (1) Lens ass'y, Image Stabilizer (part# CY3-2110-010 )<br> - Three (3) Setscrew, slotted, HLCP (part# XA6-1170-398<br> and for the 2nd time , they did not charge me anything (warranty) and in the paper work, it says :</p> <p>Replaced listed parts, adjusted to spec ,<br> One(1) Lens Ass'y , Image Stabilizer (part# CY3-2110-010)<br> One (1) FPC Ass'y , Main (part # YG2-0370-009)<br> but at the end , to me ,nothing changes . That why I'm confused and need your advice/thought.<br> Thanks.</p>

<p>I got a used 100-400 L IS mark I . This one is made in 2001 , according to the lens code (UP). The IS On/Off button on the lens still used the sign "I" and "0" instead of "ON" anf "OFF".<br> When I press the shutter button/back focussing buttom halfway to activate the IS system, the image in the view finder does not stay still like other canon IS lens , but still moving due to the shake of my hand (more at 400mm).<br> I tried on my friend 100-400 IS Mark I and the image stays still after the IS is activated (this one must be newer due to the lens code).<br /> I thought that my lens is defective so I sent it to Canon to fix the problem . It cost me almost CAD $ 400.00 to repair. But same thing happened . I phoned Canon and sent it in the second time. Canon fix it again (?) and send it back to me. The image in the view finder still not steady when I turn the IS on. The IS system makes a sound proving that it is working or trying to work but with no result (?).<br> I do not want to send it in the 3rd time because it looks silly to me .<br> What do you think ? Is it normal for a lens that old ? I'm really confused .<br> Thank you for all the input.</p>
