Canon 24-70 F2.8 II - Error 01

Fuzzbass666 — Sun, 10 Sep 2023 11:44:20 GMT

I've had this lens about 10 years now. It was first repaired for the issue back in 2019 (replaced the aperture module).

I'm getting the same issue again, 4 years later - and cleaning does not resolve the issue this time, so I'm guessing it's probably the same mechanical issue as last time.

Is this particularly prone to this issue? Anyone know why?

The flex cable in the lens has failed. Time to get a quote from Canon to repair it.

I kinda know that - as it’s not the first time. The question was more to understand if / why this lens is particularly prone to it, especially after having been repaired once before. Do you know if 4 years is a reasonable time to have it recur?

I own a copy of the EF 24-70mm F/2.8L II USM lens. I've never had the flex cable fail in my lens. The oldest lens that my dad still owns is the EF 70-210mm F/4 lens. This lens is from 1987 and it still works like it did brand new in 1987. This was Canon's first telephoto lens to the new EOS system. This lens uses an Arc- Form Drive AF Motor. All released lenses for the new EOS system used this until 1992.

It seems to be a flexing/wear issue. Actual time is not a factor.

It is the one that gets significant use, but weirdly my 20-35 F2.8, which is another workhorse (and a lot older) has not the same issue. Go figure.

Thanks

The EF 20-35mm F/2.8L lens is another one of those original EOS/ EF system lenses. That lens also uses an Arc-Form Drive AF Motor. These lenses have limitations when it comes to fps.

And my favourite wide angle - perfect for my use.

This lens lacks support with DPAF (Dual Pixel Autofocus), distance encoder for E-TTL II, Also no full time manual focus and an fps limit of 3-4 fps in AI Servo. When this lens was released E-TTL didn't exist it wouldn't appear until 1995. Canon was still using A-TTL and TTL flash metering.

Lot’s of things it doesn’t do - but as I say, it’s perfect for my needs. Light, small, wide enough.

A gem.

Canon can't guarantee FULL compatibility with old lenses that are paired with newer cameras that have Dual Pixel Autofocus. The lens must have the hardware needed for it to work. The lens will still work like it always has. But you won't get the full potential from your camera because of the lens' hardware limitations. So don't expect new features to work with old hardware.
