Of course you´re right and that is what pisses me off. And, unfortunately we as customers, in most cases, let them bully us into their corner, where they lock us up and suck us dry. This time my disappointment was just too much and I´m preparing to exit.Tremendous resolution! No improvements in DR, no improvements on noise, no support for high precision manual focus, due to fixed focusing screen (they put it on the 6D and 7DII, but not on their flagships ), exposure metering is not following AF, no illuminated AF confirmation ... There are some more, but these were on top of my wish list. I got one out of six.
Not including support of changeable focus screens is easily explained as a business decision.
If manual focus was easy on 5Ds then the likely hood of people buying MF Zeiss lenses is much larger instead of them buying AF lenses from Canon.
Most people who buy 6D and 7DII will not spend the money on MF Zeiss lenses so it is safe to allow them to change focusing screens.
Remember Canon's first priority is to maximize profits, if you look at Canon's decisions through this lens then most decisions make sense.
Focusing Screens in Taiwan will make an S-screen that will give us that functionality. But it is a nerv wrecking operation to change the focusing screens and it must be done on a bench with tools and good light, ref. how it´s done on the 5DIII. And you have to be able to change them, preferably when you´re in the field, if you want to use lenses slower than f2.8. So I can still get it, but it will be a lot of hassle involved. I would not be surprised though, if the 5Ds will require that you go in from the viewer side to get it out, meaning it will be impossible to change outside of a CPS shop.
How many of you shoot macro with the 100 f2.8L IS Macro? How many use manual focus in doing so? I suppose quite a few. In a sunny and high contrast situation, it is a lot easier to focus that lens manually with an Ec-S focusing screen, than using live view. I would have loved to use a capable 5Ds for that.
Another good use of a high precision focusing screen is when shooting portraits with very shallow depth of field, like with an 85 f1.2L II or 135 f2.0. Why do Canon provide manual focus override with most of their lenses, if you are unable to see that you actually got That eye in focus? I would have loved to use a capable 5Ds for that.
So Canon´s protective attitude, fuelled by their fright of letting any other company make money by allowing customers to use other lenses their own and their view on how to maximise profit, ended in my case in not buying the 5Ds and also not buying the 11-24. And I doubt I will buy any more Canon lenses. I will also stop recommending Canon to people asking for advice. A drop in their ocean, but it might be that I´m not the only one.
The reason that the new 5Ds and r don't have interchangeable focusing screens is because they are fundamentally a 5DIII with different sensor and mirror mechanics. I don't believe Canon intends to produce these in quantities anything like approaching 5DIII numbers, so there isn't really much new tooling.
(Conversely the reason the 6D does have interchangeable screens is because it uses many 5DII components).
The 5DIII offers much improved AF accuracy over the II, thus negating the need for a manual focus screen. Or does it ? This is the real question. Did Canon drop a feature that many people do really want ? Certainly judging from those of us on CR you would say yes, they did.
Time will tell to see if the feature returns in the 5DIV.
I don't agree with kphoto99. Purchases of Zeiss manual focus lenses are a drop in the ocean compared with AF, even the most expensive L ones.
