EF 70-200mm lens issue / twitching

JSPhotography — Sun, 08 Oct 2017 11:06:15 GMT

Hi There,

I was wondering if anyone could help me please?

I recently attached my Canon EF 70-200mm USM II 2.8L lense to my Canon 5D Mrk III camera. I attached it and it started to make a clicking sound, and when you looked through the view finder it would be jumping up and down, i also noticed it was going inbetween F.stops. It had nothing to do with the camera, as my standard lens was working fine.

Anyone had the same issues? If yes, than how was it resolved?

Thanks in advance

James

Is this the first time you've used this lens, or just the first time it's exhibited this behavior? Is it the "IS" version of the lesn? Did you get it new or used? Are you able to take pictures with it? If so, with what result?

Failing IS. It needs service. Call Canon service.

Hi Bob,

Its just over 2 years old now, and yes its the first time this has happened. Yes is the IS version, i did get it new, i am able to take pictures, but they are blurry as the glass keeps moving.

Canon will typically give you quote within a week. It take a bit longer around holidays, when sales volume is peaking.

"... would you know a rough cost for the rectification?"

I don't but Canon may have a flat rate. Because they will go through the lens and make it perfect. They will give you a warranty on their work, too.
