A Canon 17-85mm IS lens I just traded for has developed the infamous "Error 01" problem where it will not operate in aperture priority mode
Yes, cleaning lens contacts makes no difference, and the lens has been checked on two Canon DSLR bodies and shown the same error. A dim viewfinder hints that the aperture blades are stuck.
The unnerving part is that I tried to set up a repair request online, I could not accomplish that. Instead I got this message:

Unfortunately, that's a hint that the lens can not be repaired by Canon.
So, I have a few questions which may or may not be answerable: does anyone know how much a repair on this lens may cost, and if Canon can not handle the repair is there anyone who can?
Canon have a limit on the time within which they will service lenses and I would not be surprised if they decline to service this one. You may find third parties willing to do the repair, but it could well be a case that the cost is more than to get a replacement unit.
A good working used EF-S 17-85mm is around $200+ bucks. So, that pretty much limits how much you can spend to get your fixed. It is s pretty nice lens so a worthwhile one to have. Try Midwest Camera Repair. They will give you an estimate. Keep in mind shipping and insurance costs too.
