alan_chan4 Posted March 16, 2008 Share Posted March 16, 2008 I have just received my brand new 70-200/4L IS which seems fine, sort of. What Imean is everything function as normal, except it BF slightly at 70mm, and thetop edge is a bit blurry and more severe toward the top right corner at 200mm. Iam using 40D so I thought the blurriness would be more severe on 5D, but itwasn't. Anyway, to keep it brief, I think my copy is not so poor worth gamblingon an exchange (mail order) hoping the replacement would be better. So, of the 3Canon service centres in Canada, which one has the most reliable and bestrecord? And which one to avoid? Also, the IS is louder than the EF-S17-55/2.8IS,is it normal? Many thanks!

serguei_fenev Posted March 16, 2008 Share Posted March 16, 2008 I had a very good experience with one in Mississauga. Prompt service - they fixed my 24-70 within a week and shipped it back for free even the lens was 4 years old. Cheers. Link to comment Share on other sites More sharing options...
claude_lamoureux1 Posted March 16, 2008 Share Posted March 16, 2008 Just use the Canon web site to find the closest service center. I went to the one in Montreal and can only report that they did a great job cleaning my DSLR. http://www.canon.ca/product_reg.asp?lng=en&pr=3&shlink=http%3A%2F%2Fcanoncanada-loc.custhelp.com/cgi-bin/canoncanada_loc.cfg/php/loc/enduser/loc.php?p_locator_view=ConsumerService \CL Link to comment Share on other sites More sharing options...
peter_j2 Posted March 16, 2008 Share Posted March 16, 2008 I guess you have no problems shipping (or hopping onto an Air Canada flight) to any of the Canadian Canon locations? Canon Mississauga is the only place I have visited 3 times. No problems so far. They even couriered my warranted camera back to me free. Furthermore, they were going to courier my other out-of-warranty camera to me free also! But, I don't trust couriers with delicate electronics and decided to drive the 50 kilometres to pick it up.

mendel_leisk Posted March 16, 2008 Share Posted March 16, 2008 I think the IS being louder likely means nothing. I have a 24-105 and 70-200 f2.8 with IS. The latter is noticeably louder. Good luck with your lens. My 24-105 is just now at the Calgary service center, for similar issues as yours. This is my first experience with Canon Service, and the lens is out of warranty. I just wish I'd got on the ball and checked the quality sooner. There's an automotive expression "blueprinting". It meams something along the lines of: product comes from the factory, with coarse-adjusted components, each within spec's, but sometimes barely. Sometimes having multimple components near their spec. limits can add up to an overall product that's out of spec. Blueprinting is the process of tearing the product down to it's components, and esnuring each is as close to it's "blueprint" spec. as possible. Then re-assemble and verify overall spec. is as close as possible. Seems like sending a lens into Canon might (hopefully) accomplish this. Link to comment Share on other sites More sharing options...
alan_chan4 Posted March 17, 2008 Author Share Posted March 17, 2008 Thanks everyone. Mississauga it is. :) Link to comment Share on other sites More sharing options...
zave_shapiro Posted March 17, 2008 Share Posted March 17, 2008 A few years ago I used the Calgary shop to fix my A2. They were slow and they missed something. Sounds like Mississauga is the best idea! Link to comment Share on other sites More sharing options...
