Great thread indeed

instead of buying yet another lens, I opted to upgrade all my existing ones, i-e

canon 100-400 is L II ( becomes 71-286 f3.2 f4...),

sigma c 150-600( become 3.5 4.5, 106 426mm ),

canon 50mm 1.8 become 35mm1.2;

24-105 f4 becomes a very nice 17-74 f2.8

sigma 8-16 vignetted badly at the widest end ( 5mm or so now ), the rest is okay

I think I'll buy another viltrox speedbooster for my sony a6500 ( what with the clear image zoom, I'll get even more versatility )

That's nice. Have my 6d pair with the m50. Image quality and low light 6d is great but ain't great in  auto focus. While m50 is great auto focus but low light is not good. Hopefully speed booster will be good overall. I shoot jpeg a lot. so vignetting is a big deal for me thats why I'm asking
