I do not  see any possibility: Picture

No tripod collar - a show stopper for me

My impression: Solid rumors come up rather weeks then months before.

How do you present the pictures? If you do not need the 42MP, simply go for the A7III.

Exactly - the absolute noise is similar, but the noise-signal-ratio is worse in dark areas making the noise more visible.

200-600 + 1,4x makes f9 For me it is quite clear: If you mainly want to use the long end, the 200-600 is the better choice - it is 2/3 stops faster than the 100-400 with teleconverter. If you want ...

If macro is not what you want but having one lens only, I would do the oposite to croping: Get the great 24-105 and make several pictures that you can stitch together for wide angle view.

I have read the animal AF is working for cats and dogs yet only, other animals are following later.

You must not assign Eye-AF to a custom buttom - deactivate it in the menu. Only one of each possiblities at the same time.

I would spend some more money for the Sony, assumed the optical quality is similar to the Sigma: - €150 because it is a Sony - €50 for the customizable button on the lens - €1 for each gramm it is ...

Sony - only the Batis and Loxia lenses are made by Zeiss. All lenses on Sonys webside are made by Sony.

I would like an even more compact extending 70-200 f4;

I would go for the Metabones or the Sigma MC-11 instead. But I do not really know the performance of the Viltrox, only had the Sigma.
