Oooops... 80D may have the same focus issues as the 70D

Disappointing.

Take a look at the 10:30 mark.

Should be interesting. I remember my 70D going back to canon service 3 separate times for a similar issue.

What did the 70D focus issue thread get to. 90+ pages ? Was a lot more before the admin cleaned out all the fanboy post

For 7 years we have known that the AF point in the viewfinder may not align exactly with the actual AF points on the crop bodies. Shouldn't be surprised at this point...

No you have known it for 7 years.

Joe blow who buys a camera in a camera store doesn't know it and I really doubt canon informs him of such either.

That video simply isn't enough to declare "the sky is falling" for the 80D. That simply wasn't a great test, and it does look like there is focus where he wants it, it is just slightly off, if that. As you know, some video where some guy tried to focus on a spot with obstructions and didn't really describe his process just isn't enough evidence, or any, of issues.

Just my two cents, here. I currently shoot a 6D and a 1DIII. They are the first Canon bodies that did NOT have discrepancies between the visible and the actual AF points. I thought, surely, this must be common knowledge.

Not sure what you are arguing for or against, but I stated crop bodies... Also the 1D3 went through its own hell, with recalls, etc. on AF issues. Much worse than anything seen on any of the APS-C bodies.

Just this. I watched the video, and the maker put an AF point right on the border between two vari-distant targets. He got variable results. Surprise. I did the same thing with 500D, 450D, 60D & 70D. The center point is usually really close. The lower points on my 60D overlapped the top half of the VF box they were assigned to.

The video test was too flawed to mean much of anything. To be fair, sometimes he lauded the 80D, and sometimes he blasted it. With little real evidence, and no definitive conclusion, I felt it was primarily wasted time, like most video reviews.

I had to laugh at the guy's definitions of accuracy and precision. Precision means a high degree of repeat-ability. If I focus on an item 100 times, and the camera focuses between 10.13 feet and 10.16 feet every time, it may be considered VERY precise. If the true distance is 17 feet, that camera is NOT very accurate.

EDIT:
I did check the serial number range of the 1DIII before buying, and the AF performance when I got it. I am happy with both. The 1DIII easily out AFs the 7D and 70D it replaced.

I went through that hell - thanks for reminding.

Me too, just one of the 2 1D3s though.

Totally agree.

What are you agreeing about?

I'm so confused!

Follow the link he replied to...

The AF points are not discrete sensors. There is actually only one planar sensor and the points in the viewfinder indicate areas of peak sensitivity and these extend beyond the red squares. This is true of all Canon DSLRs (and probably all phase-detect focusing systems). It's no secret. Canon specifically mention it in a number of their publications. The attached was taken from the 1DIV white paper showing the difference between single-point and spot AF.

Wow. Maybe I just actually did learn something about all of this. Y'all set the bar way higher than would ever matter to little ole me.

Carry on.
