Canon 1000D : ERR 01 message with 70-300 lens

[rocket9244]

I got a different lens for my camera and on some settings, (usually full auto mode)  I get an "err 01" communications between the camera and lens is faulty, clean the lens contacts",

but other shots / settings it works perfect. camera is Canon 1000d and lens is QUANTARAY for Canon 70-300MM 1:4-5.6 LDO Macro. what could be issue, could the camera cant handle some settings and or vice versa? heres a moon shot on manual, iso auto and macro @ 300.

"Over the weekend, I was shooting with my 6D at an airshow.  The camera gave me the same error using my 70-200 2.8L lens.  It also happened when I was shooting continuous and several times.... "

You have top drawer equipment so unless a failure in one or the other, I would do a quick reset of the camera back to defaults and try again.  It is probably too new to have dirty contacts but you might try cleaning them.  Gently!

"... which is clearly a software issue.... "

You do know 1000's, million's, of 6D's work without a software glitch?  Try the reset first just to make sure.

Hello Mike Sowsun, 

Your reply here is spot on! I'm facing the same problem. I'm considering keeping the lens and just shooting it wide open all the time. I'm using the Tamron 70-300mm f4-5.6 Di LD with the Canon M50 Mk I and the Viltrox EF EOS M adapter. I just had two questions...

1. Is it in any way harmful for the camera to do this?

2. Is there any way to fix this problem?

I'd be grateful for your reply. Thanks!

1) It is not harmful to your camera.

2) There is no way to fix this.

The response from the forum about "reverse engineering" lens computer chip firmware is correct: During the early auto-focus era, third-party lens maker Sigma was notable for producing lenses that were incompatible with second generation (and later) Canon auto-focus cameras. Sigma accepted those lenses and updated their firmware under a recall program well before I got my first EOS SLR (an Elan, aka 100, around 1995), but many of the affected lenses went without. I guess Sigma came up with whatever licensing fees Canon required for the necessary engineering specs, but all succeeding Sigma lens production functions fine on Canon cameras.

You know you are about 10 years too late to respond and your reply to this thread. 

[Vsyrek1945]

And yet, you saw it. As I read the thread, I was impressed that no one acknowledged or even seemed to know how this came to be, including the author of the Accepted Solution. Now, it's part of the thread.

You're welcome.

"And yet, you saw it."

I get notices so there is no way I would have seen it otherwise. One reply in 10+ years is not a "hot" topic. You are probably in a very small group that searches for and reads and replies to 10+ year old threads. The OP who is the only one that really cares has flown the coop most likely. If it happens to be your issue, too, a better option is to start your own new thread.
