My Canon 80D has 49 focus points. But if I leave all of them enabled, the camera may attempt to focus on something other than what I want it to focus on. So, I have disabled all of the sensors except the one in the center of the viewscreen. I put that sensor where I want the focus to be tack sharp and depress the shutter release half way to lock it in, or depress the back focus button, and then reframe and shoot.

So, what use are the other 48 sensors? To me, not much. The only time I would use them is if I locked the camera down on a tripod. I would then select one of the other sensors for my focus point.

So is the Canon better because it has more sensors? No, it just has a few more whistles in the focus department.

I do exactly the same thing. I thikn that you probably started with mechanical film cameras, as did I. All those focus points confuse the hell out of me. In the old film cameras spot metering cost extra. I suppose that if I was a sports photographer multi focus points would be a great help, but most of my subjects don't move much-landscapes, portraits and pets.

Eric, no offense, but people that use only one focus point usually either don't know how to use their cameras correctly or how to set the focus system up.
My cameras have WAY more than 45 points and I wish I had more and over a bigger area of the view finder, even for portraits that don't move at all!
RARELY is the center area of my image where I want my focus to be!!!

If it were the swimsuit competition at the Miss America Pageant Heck Yes!!!!

Are you actually saying that the earth is NOT flat.

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


Nikon and Canon have many good focusing systems. Canon went down the road of having a separate focusing processor, Nikon acknowledged that system was good when they put it into their most recent camera bodies, D5, D500, D850, among others.
For birds in flight I use the Nikon GROUP AUTO FOCUS system. It uses five focus points, a cluster of 4 with one extra in the middle, shaped something like a princess diamond. Nikon allows you to put that cluster at various places in the view finder using the rear multi selector. I like the dead middle. I use it for birds in flight, as long as one of the five points is on the bird, it is in focus, this system is designed to ignore the back ground and instead concentrate on the foreground, which is the bird. My keep rate is almost 98%. I use the Nikon D500 with the Nikon 200-500 lens.
I am not discounting the Canon system, many of my friends own the Canon D7 Mard II and use the new version of the 100-400 Canon lens and they too are very happy with their results for birds in flight.

In some scenes hell yes, in others no but for those that I do I have them at hand. Don't want to use all, use spot or partial or center........ It's like the old 4 barrel carburetors on a car, you only used the second two when you floored it for speed.

Sounds like the BIF use a cluster in the center is an excellent use of additional points and would be valuable. I have not really ever done BIF but sounds like something to try.

I have used both Nikon and Canon cameras they both focus great. Now Sony has come out with fast focus cameras. I believe that a person could get a good photo with any of the systems. I think different focus points are a great idea but the question should be how easy it is to change focus points on the camera while your taking a picture. I don't know which brand is the easiest that would be my question.

Since 1987, Canon has had superior AF ! - but NOT for the reason of number of points ! It has more to do with lens control.

Canon has written the book on AF.

But, Nikon, in the last few years, has caught up with Canon for the most part - and now Sony is challenging also.

How do I get auto focus to work in dim light?
