Oh, I did not use the 45 point autofocus.  I only used the single center point autofocus.  I should change to the 45 point autofocus?  That doesn't sound right.

Those were shot with aperture priority, f2.8, but it should not matter.  The camera should focus regardless.

Re: Refurbished 80d...blurry out of focus photos.. HELP!

The problem i had is when using 45pt autofocus. If i took a photo of a car, and had 20 boxes lit on the car and 2 on the ground, it would put priority on the ground because its closest to me.

Not sure if that's your problem since you took a photo close up to you.

The other problem i had with this camera is shooting with my prime lens wide open. When i use my 50mm 1.4.. anything under 2.8 will be blurry. Figured that was a problem with the lens.

Did you try another lens?

Yes, I tried several lenses. All had a similar problem. I will shoot in live view until I send the camera in for calibration. Hopefully it can be fixed. I suspect a batch of cameras got through quality control that were not quite up to spec. I was unlucky enough to get one of those cameras. Bummer, I wish Canon would just swap me a new camera for my current one. My current camera is less than 2 months old.

I have a brand new 80D and I have the same viewfinder vs. live view focus problem.  I think it's the camera.  These images were shot using a tripod and timed (2 s) shutter release.  My hands did not touch the camera when the pictures were taken.

 

One shot, single, center point autofocus, 24mm, iso 400, f 2.8. It's a little hard to see, but the top image was autofocused through the viewfinder. The bottom image using live view.  My old Rebel T1i takes better pics. Guess I have to send the camera in for warrenty repair.  Very disappointing, brand new $1100 camera.Compare.jpg


It appears that you may need a bit of autofocus microadjustment. But if you're going to rely on a 2-dimensional test pattern to do the calibration, make sure that the pattern is absolutely perpendicular to the line of sight. In your images, it appears that the right side is in slightly better focus than the left, suggesting a slight deviation from perpendicularity.

Posting photos with EXIF data is useful.  Screenshots are totally useless for evaluating the focusing ability of the camera.

Re: Refurbished 80d...blurry out of focus photos.. HELP!

That is probably true. I did not level off the line of sight. The center focal point was aimed at the middle of the chart in all images.  I did a couple more experiments and I think the problem is focused (excuse the pun) on the middle focal point. When I select the single focal point one up (above) from the center point I do not get the same result. Using the focal point one up from the center point, viewfinder and live view images are sharp with multiple lenses.  (I know it's hard to see, but the EXIF info is in the right panel of all images.) These images were shot using the focal point immediately above the center focus point.  The top image was shot through the viewfinder and the bottom image was live view. If the camera continues like this, I can live with it.  I just won't use the center focus point.  Still a bummer though on a brand new camera.
