Interesting, wasnt expecting that
Out of curiosity which would you hire given the choice? The slight difference in rental costs isnt a factor, just purely based on use between 200-400mm
Thank you

Have you considered the 200-600 G? Briefly, haven't used either but from what I gather size and weight are broadly similar, Image quality between them is heavily debated but tends to focus on comparisons of the 100-400 & TC @ 600mm vs the 200-600 whereas I imagine ill be between 150-350mm most of the time where I think the 100-400 has a slight edge
Focus speed was the main concern, tricky and changing lighting with a relatively fast moving subject made me think the 100-400 might be the better option For your stated use case, I don't think you will find a significant difference in image quality or focusing speed. I've had the new 100-400 for a week now, and I'm already regretting having sold my 200-600 because it was such a versatile lens. If I was doing a boat trip to photograph eagles and AF speed was my main concern, I would take an A1 II body and the 200-600 G. Otherwise, I would try to make do with the A7R VI (in and out of crop mode) with the 100-400 f4.5; constantly attaching and removing TC's on a moving boat is not fun. In many cases, if one is tempted to put their FF camera into crop mode to get extra reach, it probably makes more sense to leave it in the regular FF mode, and have the extra space around the subject. Sometimes subject motion is erratic and we can't always keep it centered, and you can always crop in post.
With a camera like the A7R VI, the memory buffer can be a limitation if the eagle action gets hectic - shooting in crop mode increases the number of shots you can take in a long burst. I have mine set up with a custom button to toggle crop mode on and off so I can quickly switch between the two modes.
