The Sony 150-600 is around 2K but the sigma one is around 1K so could be an option for me, but for now I am thinking the wider lens will be better for me,
Mirrorless is for sure lighter thats why I switched initially, but then we carry heavy lens anyway LOL
The Helios 44-2 gives a nice bokeh an swirl, I took a few shots with it today but the su kept hiding behind clouds so did not use it as much as I was hoping
I dont get out in places with wildlife much but maybe that is something i will look into when I retire and have more time

Those gigs sound interesting good luck with them
