To repair, or not to repair. That is the question: My trusty Canon EF 24-70 2.8L (not the ii version) gave me the nefarious Err 01 on my 5D4. All my other lenses are working well. So...

My trusty Canon EF 24-70 2.8L (not the ii version) gave me the nefarious Err 01 on my 5D4. All my other lenses are working well. So, that narrows it down to the 24-70. This is the older version without IS. Cleaned the lens contacts several times with different cloths and used a LensPen as well. No luck. Same Err 01.

Seems Canon no longer supports repair on this lens as I believe they stopped producing it 10 years ago. So, should I skip the repair and shop for a EF 24-105 ii instead? (I only buy used...)

TIA.

The only question is the cost difference between repairing and replacing
I believe you answered your own question when stating Canon supports repair of your lens.

Looks like it's time for a new lens KEH has several Canon 24-105mm f/4 L IS USM II EF-Mount depending up the condition from around 885 to 700 dollars

Either the vII models of the 24-105 or 24-70 are superior and tangible upgrades, either for DSLRs or mirrorless.

One of the viewers commented, "After seeing this tutorial, i ordered the "aperture" part from ebay, and just fixed my lens now following this tutorial. Everything works fine now. I can now change my aperture (which was stuck at f/22 b4 the fix). I also check sharpness, infinity focus etc to make sure there was no side effect after fixing the aperture, and happy to say all is good "

Did you also clean the body contacts on the camera? If I recall correctly, a little lint in the lens mount contacts can provide just enough separation of one or more of those contact points from its lens counterpart, and interrupt the signal.

Yikes!! I used to repair carburetors in a past life. Today, there is no way I would attempt that!

All other lenses work fine on that body.

If you buy a used one it is also old. With a new one you cenexpect another 10 years of use.

A guideline might be 80% of the purchase price. That’s what my insurance coverage is. Over 80% and they replace it.

My policy, which is a separate rider, gives me the replacement price, or, 100%.
