佳能60D出现Err 01相机与镜头的通信有故障请清洁镜头触点是什么问题

你不是唯一的一个人，美国爱好者的大量17-85出现同样的问题，其原因就是排线设计不合理，在调Zoom的时候排线会打死弯，然后就出现接触不良甚至折断的问题。有的人是一年坏一个。但是修理也不复杂，换掉排线就好了。但是仍然会坏。现在美国有人在网上卖替换的排线，6美元一个，让你自己换。不只是17-85有这个问题，佳能的小数码S100有同样问题，调焦时会毁排线。我现在越来越怀疑佳能的质量了。

wrote:The same happened to me: after being repaired in 2009 (at
the cost of 290 Euro)， the lens failed again in 2010. When I brought it
to an independent repair centre (I was in Canada) the comment was that
it has a design mistake (something with a ribbon transmitting data) and
having it repaired was strongly discouraged. I took their advice and
bought the 15-85 - until now very pleased. No idea if the issue has been
solved by Canon in the 17-85 still on sale today.

The repair centre is right. The ef-s 17-85 does have a design mistake. There
is a flexi cable going to the diaphragm that bends sharply when you
zoom in and out. The problem is worst at the wide end.I had my
lens fail and I decided to repair the lens myself. It is not something
that I can recommend to everyone but if you are careful and are used to
repairing equipment it is certainly possible. You will need to do some
fine soldering. My lens works perfectly again for about $6 for the new
flexi cable until it breaks again in a few years. Canon definitely
dropped the ball here. Every ef-s 17-85 will fail eventually and that is
a pity cause it‘s a very useful lens.
