Hello. I just received the Tamron 70-300 with VC.
I read its manual and it mentions that :
"With the vc mechanism there are occassions when the image in the viewfinder blurs after the shutter button is pressed down halfway"
Fine, this "blur" is actually not a blur but more like a shaking. The problem is that it does it every time i try to refocus after about 1 second. Surely this is not silent at all.
So if i press the shutter button halfway, i get that shaking, when i release it, that shaking comes again. After 1-2 seconds when i try to focus somewhere else, that shaking comes again. I do understand that its the VC mechanism, but i've never noticed something similar with the IS.
Is this normal ?
Furthermore, the lens has full time manual function. In the manual it says :
"First set the focus mode to AF, You can adjust the focus manualy while turning the focus ring in the shutter button pressed lightly"
Bellow this it mentions also : "When set on AF mode, interfering with focusing ring may cause serious damage to the lens mechanism"
This sentence says tells me in other words to use the full time manual with caution as it may damage the mechanism. Do i understand it wrong ?
I thought that i just AF and while having the shutter halfpressed i can override with the focus ring. Not ?
