Did you find the 61 AF points too few? Should everything increase in number? As for the spread, I recall someone saying that the AF points can't be spread as close to the edges of the frame in a FF camera, something to do with the angle of light being too acute round the edges? So a crop camera like the 7D2 can have them appear to be further spread, because it's a smaller sensor. (Genuine open question - do other brands' FF cameras have their AF points spread wider than Canon's?).
By that reasoning did the 5D3 really need 61 points? Maybe they should have just stuck with the 9 from the 5D2. I think that things which help the photographer should be improved upon, such as having more focus points at a wider spread.
So are you gonna answer the question? Let's take your logic to its conclusion: a thousand AF points is better. And a million is better than that! There's such a thing as diminishing returns. I'm certainly not saying 61 is enough, or too many. But you seem to be stuck as 'more is better waaaaah!'.
time123 said:I guess I am still a bit shocked that after 4.5 years a company worth billions upon billions of dollars would more or less recycle their tech and not do anything else. Especially when comparing the jump in tech between the 5D2 to the 5D3 and the considerably shorter release schedule between those two bodies.
I can only assume they thought the number of points was enough, and that other aspects (like metering sensor, AF algorithms, etc) were more important. Each generation won't improve in the same ways, different areas of technology are at different stages of maturity.
Well, if you don't feel that 61 is too many then we are already on the same page but you'd be better off not setting up logical fallacies (good old slippery slope) and arguing against those and especially making a fake crying sound. I cringe every time I see that kind of unintelligent junk as part of a debate/discussion on the Internet. Is that how you actually discuss things with people in real life or is the anonymity of the Internet taking its toll? As I had originally said I was surprised that Canon didn't increase the number of autofocus points so obviously, yes, I felt that 61 was too few for a product that is 4.5 years newer. I thought that your question was rhetorical because this inference of mine was clear but apparently not for everyone. This topic is about what people feel are shortcomings on the 5D4. This is one of mine.
There are plenty of advantages to a camera that has more auto-focus points with further spread. If you only shoot with the center point then only use the center point. But if you are using a very wide aperture focusing and recomposing can easily throw off the shot. Or capturing moving subjects coming in from further from the sides or top/bottom of the scene. The scenarios where this is useful goes on and on. There are plenty of photographers that find more points with more spread useful even if you don't.
Although 100% coverage would be pretty wild but the AF system and the things you could do with something so complex would be crazy. But I couldn't imagine the "Canon 1DX VII Auto-focus System for Dummies, Volumes 1-4" being a very popular seller. I never had a chance to use it but the Samsung NX1 had somewhere around 90% coverage. So yes, in many instances more is better and of course only to a point. Again though, arguing against conclusions I didn't make isn't conducive to a productive discussion. In fact, you might say it is pointless (get it? Bad puns for everyone!)
Sure, new generations won't increase in the same ways but the big talking point variables - which also tend to be very useful - in product lines that only come out once every 4-5 years (or fewer in for certain brands of cameras) generally increase or decrease for the better with each iteration but this was certainly an exception. I'm not discounting the other improvements which seem to be pretty excellent. To me though calling a piece of the technology mature so that they don't have to make any major advancements is the same type of excuse as calling them conservative and one that I don't buy. I'm sure their marketing team did their homework, decided that not too many people wouldn't be up in arms about having the same number of AF points and they could still make tons of money so that's what they did because they know once you are tied into an ecosystem they kind of got you.
We may need to agree to at least partially disagree here.
Um, ok :
What logical fallacies have I stated?
As I stated earlier, I *believe* I heard a credible person here mention at some point that the absolute spread of AF points on FF cameras is limited - with current technology*. So more AF points would mean more crowding. You can imagine an AF sensor that spreads them across the frame, and then there's room for more, but that seems wishful thinking at this point. Selecting one can already be finnicky in some shooting conditions, and having more, smaller, more closely packed AF points wouldn't make for better handling. It might allow for finer control, but at some point the returns are outweighed by the time and complication of selecting the precise one you want. Right?
I have no problem agreeing to disagree. Loads of folk turn up round here complaining that Canon is too conservative. I just don't see the point of making so much fuss. There are other, perhaps one could say, less conservative brands. Buy those. Or don't.
*If you have evidence that I'm wrong, fine - great! But do you?
PS you're anonymous here too. It's irrelevant - the quality of arguments and evidence is what counts.
