Repair on canon 500mm F4 L lens

[Iyke_zachariah]

Hi I was wondering if anyone knows where i can buy a couple replacement parts for a canon 500mm F4L IS USM lens. I’m needing the lens barrel and autofocus ribbon cable, part numbers YA2-3733 and YH1-0586 respectively. I’m based in Australia, happy to get them shipped if need be but I can’t seem to find anywhere that will sell them and just wondering if there is someone out there? 
cheers,

iyke

Greetings,

Cameras or lenses, my advice is send it to Canon for repair.  If its older, (unserviceable) I'd try and find a good repair shop.  Regardless of lens generation, hats off to you if you can pull off lens disassembly / reassembly on your own. I got hits for the parts on eBay, but I'd still want the service performed by someone who did repair as their business.  I hope it works out for you.
