I shoot Canon but the scenario that you are mentioning, even I would take the D850. I've seen video out of it that are just fine. The 5D mk IV is a good camera but as a Canon shooter I was disappointed with it's specs.
Is this purely on the basis of the body? What about the rest of the system like lenses, accessories, support, etc?
Following your answer:
1. manual focus
Even the D850/D500 AF which is superb will sometimes pick the eyebrows or the frame of the glasses instead of the eyes. With wide open glass like my 1.4/105E you see the diffrence. Both cameras have the same pixel density. On the D500 viewfinder I can correct by hand.
2. Iso performance
I would not say that the difference in sensor performance is big between the D500 and the D850. With the D850 I apply color noise reduction more often and the performance of the D500 at 20.000 ISO is stunning. The sensors differ in character. The D500 has a more cleanly look, analytical I would say, the D850 a more film like magical character esp in the low ISO. Color differentiation of the D850 at low ISO is as unmatched as the ISO performance of the D5. With her 64.000 ISO is still usable, 36.000 ISO is still very good. But the D5 is far to specialised in the sports field and low light field for me for the price. The D5 Sensor in a slower lesser body for 2500€ would make a great camera though, my third body...
Ah, that makes sense. My D60 is only equipped with 10 MP. While it still produces some great photos, there really isn't much of a difference between eyelashes and eyeballs if you're shooting anything further out than an uncomfortably close headshot.
Thanks for that insight. I'll look further into the D500 to see if it could meet what I'm looking for.
If stills is your main thing then the D850 is a clear winner!
It took all the goodness of the D810 and took it to the next level, but again if you feel a pull toward the 5DIV then get it, its also a good camera.
You are locked at the D810 specs not considering the D850 is a brand new camera with a new sensor which has totally new technology (BSI).
If you want to know exactly how the 5DIV is compared to the 5DIV then wait longer till we get more information about how they are compared.
I want to repeat, both cameras are great and you cant go wrong with either, the D810 was considered in many ways to be able to produce better images then the 5DIV from all the reviews I saw, I am expecting the D850 to be able to do same (if not even better) with far more resolution.
Somehow I feel like you want to find why to get the 5DIV, to me this looks like you want (deep inside) the 5DIV so just get it, its a good tool, more then adequate for what you want but if you want the best camera the D850 is the clear winner (in specs) and the camera I will recommend.
I've been recommended to rent both cameras. It's not particularly an expense I want, but I know that the cost of the body + a lens would be much larger so I should be sure about what I'm buying.
I do feel a pull toward the MKIV, but I want to be sure that I'm not passing up a camera with superior image quality just because I want to have already made up my mind.
Above are two examples where the MKIV appears to have an edge for my eye. Am I missing something?
take the same picture of a real person (not a photo) in a real environment, then take the raw files and try to recover the shadow data on each.
I think the mkiv compares closer to the old D810.
look at what happens compared to the old d810 when pushing an underexposed shot +5EV:
Canon 5D Mark IV brings dramatic dynamic range improvements to the 5D line
Yes, you're right. A real world example is going to be more convincing than a lab test. I've had difficulty finding any evidence directly comparing these two cameras in a real world scenario.
Thank you for the link!
The stills specs of the Nikon are better, as are the hardware specs.
In real life I'd doubt many will find the canon 5d IV lacking in any area.
You're probably right. I guess it's a lot like two different televisions. Side by side there may be a difference, but no one is really watching them side by side in real life.
If you have the funds, by all means get the D850. Most of the time budgets are involved so we tend to try and save money for the OP.
I have a D850 waiting on me, after I fly home tonight.
No budget concerns here! I appreciate it. I simply want to make the purchase which gives me the absolute best and most capable tool in my hands.
That's very exciting! Please share some shots when you can! Portraits would be great, if that's something you do.
