Sigma 150-600mm w/ MC-11 adapter w/SonyA7RIII

[D.R. Smith]

Hey if this is the wrong forum for this question, I apologize in advance.
I need a zoon lens for my new A7RIII that is at least 600mm for nature, wildlife, birds, etc photography.
Ideally, I would get the Son 200-600mm lens, but with tax, it is over $2000 and that's stretching my budget right now.
I saw on B&H the Sigma 150-600mm w/ MC-11 adapter at about 1/2 the price.  The reviews were mixed and I'm not entirely certain it would work on the A7RIII.
I have a Sigma 100-400mm with the MC-11 that is okay, but can only really work in AF-S mode and is quite heavy so I don't use it much.
Anyway, does anyone have experience with the Sigma 150-600mm w/ MC-11 adapter on the SonyA7RIII or can you suggest an alternative?
Thanks for your time!

Bonjour,

Si vous cherchez juste un adaptateur pour fixer l'optique ça marche bien sur mais ne compter pas utiliser l'AF c'est très aléatoire.

Mais pourquoi mettre un adaptateur le tamron 150-600 existe en monture E
