When I shoot in manual I am using the back wheel to adjust ISO - I need to take my thumb off the wheel to get to the AF-On button which is mapped to spot focus with tracking, lower shutter speed ...

I have both the a6600 and the A7R4 and an A73 - also had an A1 and A9.  I think you will need the resolution of the A7R4 . if you are going to continue to shoot on the long end.  Otherwise you ...

Custom Shoot Sets is broken on the A1 since release and we've reported the bug to Sony Pro Support. If the A1 is in manual, a custom shoot set tied to a button cant assert Exposure compensation. ...

I found the issue I was having with the 200-600 - it was the Focus Priority Setting.  Now I get great results with the 200-600 and really no reason to think about an A1

If you can make the difference in price. - the 24-105 is much better. Also note that this lens has the one flaw that it uses a glued down spring in its internal mechanism - and if it become ...

Yes - similar to my setup - highly recommended - and the strap looks just like the the Waka one I recommended earlier in this thread. I like to use a quick release attachment that plugs right into ...

Sell it.... I had the 24-70 and was similarly disappointed. The 24-105 is so much better - versatile, and every review puts it in a class up there with the GM lenses. The current 24-70 2.8 GM is ...

Agreed - there are some cases where having a quality clear filter for protection might be called for - however recently I did drop a camera and a 100-400 gm lens - and while the hood protected the ...

Some have mentioned having issues with focus with filters on this lens -  because of the large hood with this lens - keeping a filter on for protection is really not needed. While I have a filter ...

FWIW - I don't use a strap to the camera with big lenses - attach a quick release swivel mount to the tripod foot. if you like you can run a safety line from the camera body to the strap in the ...

I had the same thing - was most obvious on two different 24 GM's manual focused on a stucco wall with careful attention to being perpendicular to the wall.  Similar smearing and softness to one ...

I have Sony Pro Support and I wouldn't hesitate to send my camera in for a checkout if I saw a consistent softness on the right side as you have.  As far as regular support,  I can't really say ...

Standard is the right one - some of us you had the focus priority setting were getting horrible results until we changed this setting. I might add that problems with long lenses, aren't always the ...

While this is more an issue with the A7R4 - do make sure you have Focus priority turned off in the Aperture Drive Setting,  This setting caused all manner of misfocus, soft focus issues with this ...

After a few weekends of rain i got out to the marsh this Sunday with my A7R4 and 200-600 combo. Still challenging myself to confirm the improvement in behavior with turning off Focus Priority in ...

I would concur that it might be a timing issue.  The blurring we see looks like a combination of misfocus and movement - and I've thought this might be exposure occurring while lens elements, IS ...

Agreed - misbehavior happens wide open or stopped down....

FYI - the problem with Focus Priority in Aperture Drive appears whether you shoot wide open or not.   Most of the time I was shooting wide open and stopped down to see if the problem resolved by ...

Thanks for the feedback - very happy this worked for you,.. I would say that it sounds like the Sony Support in the Netherlands is much more proactive than here in the U.S.  That they were able to ...

Mark reported some inconsistent focusing issues with the A7R4 and the 200-600, I will ask him what his Aperture Drive setting was.
