Will i benefit changing from D800 to Sony R7iii

Quote:Sorry to break the news but changing your kit doesnt improve your skills, in fact it can make things worse as you have a new camera to learn about( button positions etc)
Steve - the OP didn't mention his skills, he asked about IQ and exposure accuracy.
Any new equipment means a period of trial and error, which disappears when usage becomes more automatic.
Nick - As Steve says, if you have access to a physical store, and they hire out equipment, see if you can get one for a day or two to be able to compare.

Here's ePz's review of the two so you can easily compare the advances/changes in technology. It may help.

there's over 6 years between the two, so I don't think you'd be disappointed by changing.

Why not change to a Nikon D850, Z6 or Z7? You'll still be able to use all your NIkon lenses and you'll be familiar with the button layout, menus and ergonomics. It'll be less expensive than changing camera systems.
The Sony A7 III and R IV are excellent cameras, but so are the Nikon cameras. The IQ of all modern cameras ( DSLR and Mirrorless ) is easily good enough for most people.
The exposure is something that hasn't bothered me at all with any camera system, even if they expose differently to each other. It is a case of learning your camera's idiosyncrasies.
I changed from Canon ( due to unreliable and limited AF ) to Sony and haven't regretted it at all. I think the Sony AF system is excellent and the dynamic range is a lot better than the Canon cameras I used. I have found I need to do a lot less post processing because the files are so good.

Quote: would it provide me a benefit it terms of quality and more accurate exposure?
Unless your current camera and lenses need repairing your exposures are unlikely to be better with another system than with a Nikon D800.
If your exposures are not generally accurate it maybe you need to improve your camera technique before spending money on equipment of any make.
I am bemused as to why you are not also looking at the Nikon Z system.
As has been mentioned you can continue to use your Nikon Lenses without loosing anything (except AF if old screwdriver AF lenses) - at less cost then switching lenses - and you can get ML features similar to those in a Sony ML body.

Quote:Len,
I have used a Z6 and was not that impressed with the adapter. It works but even top quality lenses were not fantastic.
A strange comment as there is no optical or AF speed difference difference with most F mount lenses used on Z or on F mount bodies.
Quote:
To get the best out the system you really need to Z mount lenses.
The Z lenses as they get released all perform very well - with at least 2 out perming anything to fit Sony.
Medium term Nikon and Canon have an optical advantage with some lenses as Sony E does not have a wide lens throat.
Quote:So if I’m going to spend on these lenses then I might as well consider other systems at the same time.
Agreed.
