    Posted: 13 September 2022 at 18:02
Since 2 months I have the A7iv. I make a lot off pictures of soccer games. I have the idea that there is some kind of delay after I press the release button and before the actual photo has taken. Therefore I sometimes miss the action. The A99ii was faster in my opinion.
Does anyone know if it is possible that I have a wrong setting.
Settings ; AF-C , eye-AF, object-following-on, aperture-priority

Have you got the camera set to " release priority" or Focus priority " or "balanced " in the menu ?
Are you using adapted lenses or native E mount , if so what ?

I had the same impression with the same camera's compared.
Not sure yet if it is a real delay, or just the different sound.

What lens?

I find the same with my A7r iv when I use an adapted lens - like my Sony/Zeiss 24-70/2.8 on the LA-EA3 or my Canon 24-70/4L on the Sigma MC-11. The Sigma MC-11 with the Sigma Art 35/1.4 hardly has any delay. Therefore: what lens?

IIRC there can be a slight delay whilst the adapter stops the lens down if your not shooting at full aperture with the LA-EA* adapters as they don't stop down as fast as some DSLR's / SLTs . Especially when compared to an a99ii .

Try it with "release priority" so the camera takes the shot when you want it to , not when it wants too .

For a couple of test shots to find how quick this camera and lens combination can take a shot , do a couple of things .

1 ; set the camera to AF-S mode . lock on a target , press the shutter , see how quick it takes the picture now .
Do the twice , once at full aperture , once stopped down .

That'll show you how quick it can take a shot with AF .

2 ; set the camera to Manual focus , and in the menu to "release priority" .
Do the twice , once at full aperture , once stopped down .

Now the camera has nothing to do with focus , and with the lens wide open all it has to do is fire the shutter . See what happens now .

Also , how do you find the camera with a native lens regards pressing the shutter button and the shutter firing ?

Ah, that makes sense! Gonna check it tomorrow. The shutter lag is noticeable, but not too bad. Thnx!

Yep, no or minimal shutter lag when aperture is full open with the 24-70/2.8.
My Sigma 35/1.4 Art focuses at the set aperture.

You can hear the aperture stopping down and then the photo will be taken.

Thnx Neill for the info.

Sony should make the LA-EA adapters work more like native E-mount lenses. Get rid of holding A-mount lenses wide-open until after the shutter is pressed. Eliminate that lag. A-mount lenses also tend to have more focus-shift stopping down anyway.
