what issues? I posted some photos of humming birds on previous page with A7R4 and 200-600mm and that lens is insanely sharp and works amazingly with A7R4. Miracle combo....

Sharp as a tack? I wouldn't go that far. For sharp as a tack work with the 200600 look to Tony or Geoff's work. They have hands/shoulders like the Rock of Gibralter!
I live in a dark dark land, usually. Today was darker than normal. Throw in non-stop rain and what to do? My answer was a blind and a rifle rest for the camera. No way I could hand-hold this shot.

I've spoken with a Sony representative who admitted that there is an issue with the a7riv and 200-600 at the long end (though he wasn't specific) and that Sony was aware of it and had no fix as of now. Sony support is lousy and the most they did so far was to send a link to a generic article on "why my camcorder or camera won't focus..."
It is extremely frustrating to be sure and I continue to work diligently to explore if there is something in the settings, technique, etc. which might account for the af challenges. Again, there are many things to like; the resolution for static subjects is simply amazing, and the camera is surprisingly well constructed, and easy to use. Tracking modes are awful when using non-human subjects in human mode (not available in animal mode) and while the af appears to be following the subject in non-human modes such as zone, as evidenced by multiple little af squares lighting up and engaging on the target, it fails to achieve critical focus for BIF and frequently nothing on the bird is in focus (it's not as though the af grabs the leading edge of the wing) ...Show more →
This is the problem I am having as well. Sony techs are supposed to call me Monday or Tuesday. In playing today I had better luck with Wide than Zone. The actual tracking modes don't work at all for me. I actually got a few decent shots today using Wide but I am beyond frustrated with mine and look at others results in wonder. I love the way it is supposed to work, I think I must have a problem somewhere. My body is fabulous with my Canon 24 70 and 135L but I am having issues with the 200 600 and when I've tried the 400 DO II with the MC 11. Also, anything dark, even in low ISO's is terrible when you try to lift the shadows and at 100 percent is very soft. Also, I've seen some horrific CA with the 200 600 as well as over exposure using auto ISO. I want so badly to love this camera and lens combo, so I'm hoping they figure out what my problem is. I keep thinking it's just my newness to Sony and I have to be doing something wrong since so many are getting such beautiful shots. With my Canon wider lenses the resolution and performance is amazing. It's only when I try to shoot wildlife with it, even perched, that it just all goes to pot. I also have experienced having the little dancing squares follow my subject perfectly only to get home and have all OOF shots. They are more in focus than the backgroung, just very soft. Here are a few of the best I've been able to manage in the 3 months I've had it, with taking alot of shots to get them, and fairly heavy editing.
I took hundreds of squirrels in the park and only a few were in focus. They were still, so I was using Flexible Small

So you have problems with both long focal lengths? Do you have any other experience with those? Many first time shooters are rather surprised the first time they notice air quality degrading their long range shots. Also, anything dark, even in low ISO's is terrible when you try to lift the shadows and at 100 percent is very soft.
That sounds normal and unrelated to the lens. Also, I've seen some horrific CA with the 200 600 as well as over exposure using auto ISO.
Did those have strong back lighting? I also have experienced having the little dancing squares follow my subject perfectly only to get home and have all OOF shots. They are more in focus than the backgroung, just very soft.
This again sounds like air quality rather than a focus issue. Find a good static outdoor target with direct sun and compare shots at 25m to 50m to 100m (tripod or cam laying on a hard surface, self timer with hands off, lens wide open, iso320 or lower). Depending on time of day, wind and heat raising from the ground the 100m shots may be horrible, even if focused manually. I've spent days near lakes where *all* long range shots were soft due to too much humidity raising from the water.
