Canon 6D issues

[sopta12345]

Hello to all.

I bought a 6D new.

I was impressed with iso range and all of that, it took me a time about one month that i notice issue with focus.

Abouth 30 % of pictures are sharp and accurate, 70 % was out of focus and back focuesd.

I alredy have 5d mark III and couple of lenses and i already microadjust that body and everything warks like sniper.

But what i notices this is not a regular focus issue, central point, little square inside viewfinder moving up and down, left and right.

It was tested on tripod with IS on and OFF, focusing on LensAlign chart.

This is first issue for me on Canon cameras, what do you thinh, is there any miror or sensor movment or saomething like that because this is not normal from my view point 😄

Thanks

If you are set to manual single point AF mode and the something is moving around in the viewfinder, it does sound like your focus screen is loose. The 6D does have interchangeable focus screens, and given the camera is a few days old, it is possible that the bracket holding the focus screen came loose in shipping.

I already sent it today, hope so that will find solution and make it work 😄

I will post when it is done 😄

Cheers to all

"Interesting point. Is it possible for the focusing screen to come loose from its moorings and wobble around more or less at random? If so, it might explain all the weird symptoms the OP is seeing. What might cause such a condition, barring something drastic like the camera being dropped?"

The shipping carton could have been tossed and drop kicked around during shipping.  But, I would suspect that they would pack several cameras into a single shipping carton, though.  Or, maybe it was just never properly attached, as unlikely as that seems.

Even if the focusing screen were not well attached, why would the focusing screen "float" around during focusing when the camera has been mounted on a tripod?  There no moving parts in the camera's AF system that I am aware of.  There has to be something else going on.  I'm really curious to find out what it could be.

[EDIT] ... and "float" is an interesting choice of words, too.

Now I am filing that i should record movment to show what is going on but is late now but i dont know that will be possible with mobile phone camera.

I google for possible solutions and problems but with no luck, i found one article with focus floating on deepreview and issue was with dust on sensor.

Floating is closest word that i can describe, its realy slow movment upright or down, its like making fine circle.

Dust on the sensor doesn't make sense to me, either.  The image sensor isn't used to focus through the eyepiece.  I would have to check how it appears during Live View focusing a bit later.   I don't recall seeing an AF point during Live View, though.  Probably because I'm manually focusing?
