Got a couple of error 20s on my 50d today,just after i had put on a brand new canon 50mm f1.8,just started to check if it wanted micro adjusting,that need +12 to get it spot on.
this is way more than my Tamron which is +2 sigma -3
Could this error message be generated by the lens ?,put a tamron 28-75 f2.8 on that seems OK,Sigma 70-200 f2.8 that seems ok
Did the taking battery out format card,and that seems to have cleared the error problem just wondering if it may be the lens ?
anyone had these then they've gone away or im i likely to see the escalate
any advice from you if it has happened to you,much appreciated
 
Could you be being thrown by the small depth of field of the 50mm f/1.8. You may well be MAing to much (but I've not done it myself).

Sorry I can't be of more help.
 
ive had one of these before Ross,its the "error 20" that's concerning me,shows as "mechanical error" now im not sure if that Error can only be related to a BODY mechanical error or Body/Lens combination mechanical error
done a few test shots the CA on this nifty fifty is shocking,it will be going back anyway.im hoping its just a bad lens

Faulty contacts usually comes up as an error 99 message, but it sounds good let's hope it's sorted. :thumbs:
