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.

Yes, it is because it is a 3rd party (no-Canon) lens from the film era that just happens to not be compatible with the newer Canon Digital cameras.  

Not all film eras lenses have this problem and sometimes the manufacturer could "re-chip" the lens to make it work properly again.

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....  Not only that, but it corrupted 2 SD cards Sandisk Extreme PRO 32GB....  I only use the best equipment and want an answer to this from Canon ASAP!!!  I had this happen a total of 4 times on Saturday....  It seems to me like a buffer is getting full and overloading the camera which is clearly a software issue....  Looking forward to an answer.....

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.
