recently I've noticed an issue with my Tamron lens (at least I think it's the lens). My current set up:
- Canon EOS 90D
- Tamron AF 70-300mm f/4-5.6 Di LD Macro
When taking photos at the 300mm end of the focal length the camera throws an error:
Err 01 Communications between the camera and lens is faulty. Clean the lens contacts.
I've checked the gold connectors, they are clean (gave them a gentle clean anyway with a cloth).
What makes it strange is that this only happens with this lens, and only close or at the 300mm end of the focal length, anything between 200-300 is likely to cause the error. It's not consistent, sometimes I can take a couple of photos before the error shows up.
I've also sometimes noticed that the issue shows up purely by focusing on something in the distance, before I even take the shot.
If the photo is captured it is horribly overexposed - regardless of settings. I've tried to replicate it in a consistent manner but there isn't a pattern to it.
As a test, I've taken two photos one after another (within 10 seconds in this example), using the exact same settings, only changing the focal length.
I've been using this lens since March 2020 (bought it brand new), with no issues up until last few days.
Anyone had a similar issue?
