Faulty Lens

I own a Canon 18 - 85 mm EFS lens.
It now refuses to focus on A/F in so much that it keeps 'hunting'.
Is it worth having it repaired, or going for a 'similar' lens, as I have been informed that there is a known issue with this lens.
If so, any advise please would be appreciated

How about upgrading to a good used 15-85?
The extra wide is worth the cost.
Very nice on my 7D2.
Got it at Adorama for $450.
What's the market value of a working 18-85?

I'd try cleaning the contacts on both the camera and the lens with some isopropyl alcohol and either a q-tip or similar. It got one of my lenses going again...

Thanks Mr PC
Have tried that to no avail, I believe the lens is shot.

Hi. My name is Rick. I’m the owner and lead technician at Discount Camera Repair and a member in good standing here at the UHH. I’ve been doing repairs for other members here at greatly discounted rates and would be glad to help.

I'd be more than happy to repair the lens for you and keep the cost as low as possible. If you’re interested, please respond by private message or simply reply to this post.

There is not now and never has been a Canon EF-S 18-85mm lens. There are EF-S 18-55mm... And there are EF-S 18-135mm.... And there is an EF-S 17-85mm. And the EF-S 15-85mm already mentioned.

Depending upon which lens we're actually discussing, it may or may not be worth repairing. Typically a failed AF motor in a lens will cost around $300 for repair by Canon Service Dept. But it might only be a failed cable that needs replacement, so may cost less. Probably a minimum of $100 to $150 in labor alone, though. Rick or other third party repairer can probably do the repair for less than Canon themselves.

If it's an EF-S 18-55mm "kit" it's likely not worth repairing. Particularly the earlier models without IS or STM focus drive just aren't worth much. But even the later/better ones are widely available lightly used for little money.

EF-S 18-135mm IS STM is an "upgraded kit" lens while the EF-S 17-85mm IS USM is more "upscale" lenses... and both might be worth repairing, if the cost isn't too high.

EF-S 15-85mm IS USM is a top performing and fairly pricey lens that almost certainly would be worth repairing.

You don't happen to have your camera set on "spot" do you?

The UK is kind of out of my zone. But if you're ever in America...
