There was no sarcasm. I sincerely thought that could be an option. I have never had this problem but I just turn the focus ring to manually focus.
i not say its problem..its more new way for me than problem..
i just found out i can use Folow Focus in still shots with ML .. i got that -f +f ++f --f i was able to use arrow buttons to corect sharpnes ( focus ) ..but always when i push shot button camera start to auto focusing .. so in this way my seting up focus with arrows with out touching focus ring was usless cus camera after this change everytthing..in low light this T3i and AF its usles stuff camera is jsut blind ..
so i decide ask how to set this option up..i not say its problem cus for me it looks like part of ML so u guys knwo what happend and how set it up ..
i not found option saying turnoff af in liveview.. but i found something diferente..
its in Custom Functions(C.Fn) .. later i go to C.FnIV: Operation/Others/Shuter/AE Lock Button (whatever means AE )
i got there :
0:AF/AE Lock
1:AE Lock/AF
2:AF/AF Lock, no AE Lock
3:AE/AF, no AE Lock
when i set option 3 or 1 i can use folow focus in M mode to control focus with out touching ring..
im not sure if Folow Focus and End Focus Point are connected to work together or not but ..when i set lens on 18mm i got some changes in FocusEndPoint even before i turnoff FocsuEndPoint..it always back to ON..so in 18mm FEP seting them self to -22 steps.. this give me some 36 steps in focus from one end soft focus to another..so i must click 36 times arrow button to reach another end of focus..this is wit 18mm ... with 55mm on start i got in FEP +432 steps from here.but im not sure how big range of focus steps is in 55mm ..defenetly is muche more..cus i need keep pushed arrow buton around 32 second to reach another end of focus..its mean tis is super precise Manual Focusing in AutoFocusON on lens ..(its looks like this option was not included in ML or its soem cool bug or its part of ML )
when i select option 0 or 2 from
Custom Functions(C.Fn) .. later i go to C.FnIV: Operation/Others/Shuter/AE Lock Button
all this is impossible to do .. still i can use folow focus in M mode but when i push Shot button camera focusing sometinhg and kiling my focus..
but there is one more cool thng in this..when i got selected option 3 or 1 still i can use this what i jsut describe .. but it not mean i cant use Full Auto Focus from Lens..when i push zoom out button ( i use this button for zoomout photos in fast preview on camera ) camera reacting same as i use before half pushed shot button .i mean zoom out button with this setings works like button for Auto Focus ..but it not make shot just auto focusing .. ineed after tis push shot button in my remove or on camera body for make shot..
this is very cool thing for me..i got shit lenses.. my main lens its 18-55 II i thing and focus ring got some jumps and all moving up and down..sometimes precise focusing is realy anoying on this lens..but this is only 55mm.. more anoying stuff coming when i use 300mm with out stabilizer wit same jumping focus ring and clearancesand all single even smalltouche of lens when ifocusing make it extreamly not comfortalbe . (i hope clearances was translated ok) .. but now with this stuff ..i dont need touching lenss to set focus aka sharpnes ..
sry Francis if I was a to direct in previous post
Edit :
sometimes ( notalways ) when im close to reach one end of Focus wit Arrows i got message on screan.. Focus Error

,, but nothing Error happend for me.. .. its jsut message .. no error or bug is visible or somethng..
ehmm... doesnt your lens have a switch to disable AF?
yes my less got it..but when i turnOff AF on Lenss i Can`t use Folow Focus in M mode in way like i describing here..
when i turnOff AF on Lens in M mode .. ML and Folow Focus give me info what is :
Follow Focus requires autofocus enebled
when i turnOff it all these just dont work in way i describe..
i found my way and everythng is fine..but only with Autofocus Enebled on lenss
AE means Auto Exposure. Through canon custom options, Autofocus activation may be shifted from the Shutter button to the AE Lock (*) button. This is the famous Back-button focus invented by Canon in the eighties. So, amongst the following you can choose either Option 1 OR Option 3 to transfer the FOCUSING JOB from the shutter button to the AE Lock button (*)at the back;
0:AF/AE Lock
1:AE Lock/AF
2:AF/AF Lock, no AE Lock
3:AE/AF, no AE Lock
Whatever is written before the (/) mark refers to how the shutter button functions when it is half depressed AND whatever is written after the (/) mark refers to how the AE Lock (*)button functions. For example, Option 1 says: AE Lock/AF. This means that the Shutter Button functions as Auto Exposure Lock (it doesn't autofocus) AND the back button (i.e. AE Lock button marked as `*' functions as Auto Focus. So, if you want to autofocus, you must depress the back-button.
I think this explains AE Lock button and perhaps solves your problem.
one more time who say i got problem with some thng ? if any one haveproblme its not me only u
