Tokina 12-24 Err 01 on 7D

Hello, I'm in the middle of my Europe trip (right now in Prague) and my most used lens has suddenly started giving this problem.

It works fine upto around 15-16mm - but any wider, it reports an error asking the contacts to be cleaned. Have done it multiple times, but to no avail.

Is there a fix for this problem? Else, will be stuck to a 16-24 range on the lens which is not ideal but still ok.

You need to get it serviced. It happened to me too: https://photography-on-the.net …light=tokina+12​-24&page=2

You can only shoot at f/4-5 at 12-15mm. You have to be above 16mm to use f/5.6-f/22. The aperture ribbon needs to be repaired. I sent mine to THK Photo in California to get it repaired ($115 + shipping). Turn around time was about a month.

My first Tokina 11-16 had this same problem a few weeks after I got it; in exchange window luckily with Amazon so they just cross shipped me a new one. 1 year later no issues with replacement (My most used lens)

I just posted this as a new thread - but probably should have added to this.

Its 10 days since I returned from the trip. Tried the lens on my 20D and no issues in any setting..... Decided it was a 7D / 12-24 issue - but when I tried it on the 7D, works perfectly fine!!
