Tell me "my brother Sony set" :-)

As Sony's cams are more advanced and stabilisation in the body, I see sometimes people switching to Sony.
I know they have less lenses and more expensive ones from their own Zeis brand, some work with adaptors for their off brand lenses, probably this has issues too.

What would the brother set in Sony terms be in comparison with my signature concerning camera & lenses (also all with AF) and any estimations of the prices may be put next to them, thanks

Get a Metabones adapter and use your EF-mount lenses.

Depending on what Sony camera you get, AF speeds will be inconsistent with adapter and EF lenses. It is cheaper then having to fully switch brands, but there's still a price commitment. Do you want Full Frame? Do you want better low light performance or higher MP? Do you do much video work? These are all factors in deciding what Sony body to get. If you want real equivalent AF performance, then you have to look at Sony or Zeis offerings.

Here's my take on the closest you could get:

6D = A7II ($1598)
24-70 f/2.8 L = 24-70 f/2.8 GM ($2198)
70-200 f/2.8 L = 70-200 f/2.8 GM ($2598)
17 f/3.5 AT-X Pro = closest is 18 f/2.8 Batis ($1499)
50 f/1.4 Art = 50 f/1.4 ZA ($1498)
85 f/1.2L = 85 f/1.4 GM ($1798)
135 f/2L = No native option; either keep it and use with Metabones Adapter ($399), get Sigma 135 f/1.8 Art with MC-11 adapter ($1648), or Sony 135 f/1.8 ZA (A-mount)($1798) and one of the Sony A to E mount adapters (LA-EA3 $198 or LA-EA4 $348)

You could save a lot of size/weight/money if you're willing to give up a little aperture (go to 50 f/1.8, 85 f/1.8, etc.)
