Hello,

I have Canon EOS 4000D and EF 50mm 1.8STM.
I noticed that pictures taken with f/1.8 to f/2.8 are out of focus when I'm focusing on focus dots with auto focus.
When I'm focusing with live preview focus is OK at whole range of f.
I found that my camera have 9 AF points (f/5.6 cross type at centre).
Does it means when I'm using f less than f/5.6 I will have issue with auto focus?

If your camera and lens are having trouble achieving precise focus through the viewfinder, but not when in liveview, it could be the camera/lens combo will need some type of micro focus adjustment. This is actually quite common among fast lenses (F1.8, etc). Unfortunately, the 4000D does not have such an adjustment as Canon deemed it as a budget camera. More expensive cameras have this adjustment in the Menu. One option is to call Canon support and tell them. They may ask you to send both the lens and camera to them so they can adjust them accordingly. Of course, you will need to pay a fee.

What you say is correct.

But, it might be just as well to buy a new camera. Something like an EOS 30d or 40d would cost probably about the same as a repair/fix from canon, if such a thing is even possible (the 400d may not be supported by canon any more). A 40d (for example) would have similar specs to the 400d, but it would have AF microadjustment. The only downside (IMO) would be added weight.

There are a lot of folks on the other canon forum who love the 40d.
