Finally got it. watched 5 utubes and have the focusing working 100% or very close. it was the aperture drive setting i had it set to the same as my a7iv and changed it to open the lens wide to focus and bingo. funny but even on a 1.4 lens shooting wide still didnt solve the problem. so the sharper bigger pixels on the a7iv doesnt need the lens open to wide to focus acurately even in dark conditions , those big beautiful pixels are used for something
The aperture drive only stops the aperture to close further than f/11 on full frame
it does not shoot wide open it shoots at the aperture you dial in
So if you shoot at f/4 it will focus at f/4 if you shoot at f/2 it will focus at f/2
When you shoot a fast lens wide open due to the shallow depth of field the focus may shift this why nikon z series focus always at f/5.6 (which has its own challenges)
Not from what ive read. if you set a lens to f8 and using a f2.8 lens, the camera focuses at 2.8 then takes the image at F8 with "focus priority" set to on. which is what ive set my a6700 to.
It does not
Just look into the lens and see what it does when you change the aperture
Sony cameras focus stopped down, the focus priority only ensures this does not go to a crazy value if you shoot f/16 in all other situations there is little difference between the focus and standard setting
This means the camera focuses consistently also in video where again it stops down the lens but also sets the exposure. When taking photos the camera does not use the shutter speed dialled but a fixed rate and then compensates brightness
To help the camera in low light the camera will drop the frame rate of the EVF/LCD if you allow it (you may choose not to in which case it will struggle but show you a fluid EVF)
disagree, if you read the manual, if you have the camera set to "settings effect on" it uses focus peaking to show you the wide open DOF focus zone then it stops down the lens when you press the shutter button.
Just look into the camera when it focusses you cannot disagree with reality but of course you can deny it lol
Live view is a simulation not wha the camera really does and it makes no difference to how the camera focusses
In single AF the camera does not stop down the lens in normal operation however when you focus it stops down at the aperture dialled
In CAF the camera starts already stopped down at the aperture dialled
LOL, do some more testing , you are totally wrong.
I dont need to this is the way it works and is pretty well known
the reason why the a6xxx series have worse focus has nothing to do with settings simply tjis method works less well as the sensor size goes down
i leave you to your ignorance of the topic
fyi the only brands between nikon panasonic and sony that focuses wide open is panasonic
i have yet to find canon examples to see what they do
you dont even own any sony gear. otherwise you would just do the testing yourself.]
I own 2 A1 and 1 A7C II you are reaching delusional stage
Do yourself a favour taking yourself out of the ignorance spot you are
Put the camera on a tripod point it to a target and look at the lens
Sony hybrid AF system is the same and it is a known fact that the camera focus stopped down
There are two reasons for this
1, Avoids focus shift
2. It ensures the highest burst speed as the lens aperture blades don't have to move
This is the reason why Sony A1 and A9 have high CAF burst speed and accuracy no other reason
It is a setting optimised for fast moving target shooting with the lens wide open
This system is designed with PDAF in mind you can see that at half press nothing moves
In single AF the situation is different because there is a hybrid system and the camera will switch to contrast detect in desperate situations so it starts wide open then closes to focus and then goes back. You may be shooting a landscape the little movement does not bother anyone and they think you may have a low light situation where you actually want to see the display somehow
This gives you the flutter issue on the EVF where things move back and forth that does not happen in CAF
It takes five minutes and is very educational
The manuals do not tell you what actually happens so if you are reading that it focuses wide open is because you are imaging it . Otherwise please point me to the manual page where it clearly says that
anyone like to share there settings on the a7r5 that work 100% ! my a7iv has no problems with any of my lens even with a totally blacked out studio and the new a6700 is struggleing with all my lights on including the modeling light.
but it does have me second guessing now.
