Nikon vs Canon Auto Focus

Thanks - I always avoid reading the manual but now that you mention it, I think you're right.

The tendency of cameras using all AF brackets is to select the focus point. Perhaps the focus point selected by the camera is to your lickings, perhaps not.
I cannot discuss if more phase detection AF brackets is better because I do not really know but the cameras I am using right now, the D7000 and the D610 AF performance are doing a great job for me and they do not have a lot of phase detection sensors.
Sorry I cannot make any comments on Canon AF, I have not used Canon cameras except for a 30D years ago and the AF was primitive just to say the least.

I think using a Sony camera with EVF and manually focusing using the red outline focus feature would do well. ( focus peaking)

I guess so as that is what is claimed by them on this forum.

I know that this has likely been addressed. However there is a easy answer to this question. More cross type focus points are better. I agree that I choose one focus point and recompose most of the time but there are clear exceptions. First when using my 85mm f1.2 lens, at wider open stops, this recompose technique produces a less than sharp image due to the very small depth of field, and the few inches of error that recomposing creates. So, understanding how to QUICKLY change your focus point, while framing the shot addresses this issue. Having more cross points allows a sharp focus across more of the sensor. I have a Canon 5DMk IV, and I can quickly toggle a different focus point as I compose a shot. Another reason is when focusing on a moving subject, (child) the one shot focus mode fails more photos than it gets, so using the servo mode, and having the camera follow a subject requieres many focus points, sometimes I wish I had more that 65 points.

One can't have too many, that is as far as marketing departments go.

How many FP's are needed? Is there a point where you have too many?

Or whatever's closest like the dirt in the foreground. It must have some kind of smart technology to figure out what it thinks is the subject. There has to be more to it. I hope.

Perhaps it's time you considered educating yourself. Not only is it more satisfying than getting all your information from others, but it's more likely to result in an accurate answer since many, if not most, people here don't know much more about your camera than you do.

I’ve had Nikon cameras since film and never even looked at Canon seiously. I recently came across a review of a Canon camera and was surprised to find out that their auto focus system has 45 cross type sensors while most Nikons only have 15. So how does Nikon still manage to rate so high? It would seem that the Canon auto focus would make the Nikon grossly inferior. What am I missing? Or is Nikon grossly inferior at auto focus
For many years I was a Canon user: my last two (I always have two camera bodies) were the 7D mark II and a 70D. I was really impressed with the autofocus on both. About 18 months ago I changed to a combination of Olympus and Nikon and doubt I will ever return to the Canon brand. The autofocus on my Nikon D500 is stunning and in my hands the autofocus if far superior to the 7D mark II. My EM1 mark II also appears to me to be superior. You need to compare like cameras in order to obtain a proper assessment. My current two cameras are the equivalent of the Canon 7D mark II and have a far greater number of sensors.

Yes, there is a lot more to it than that.
Depends on what and how you set up.
Some cameras have face recognition and some have eye recoconition. Often focusing on the closest eye or face.
Or on moving subjects(dirt/trees do not move). Including if the tracked subject crosses other obstacles like other people or trees, the computer can recognize the contrast pattern it's following and continue to track it even when other objects momentarily cross it path like other player or trees etc.
setting focus systems up properly for what and how you shoot is key!

As I understand it, when shooting moving subjects, if you get even one of the 45 or 51 focal points on the subject, you will maintain focus. Seems like an advantage to me IF, you are zoomed out enough to contain the subject within the frame unless you are, for example, shooting at just the head of a bird and intend to crop later.
Here you go. If you cant believe Canon who can you believe??? http://learn.usa.canon.com/resources/articles/2016/eos-80D/eos80D-AF.shtml
