Help needed

[Motrr]

I have the canon 6d with 50mm 1.8 lens.

A nice combination but I want something more. I make pictures of children, newborns and families.
inside and outside. Newborn lifestyle shoots are always inside. Now I doubt between these lenses: 24-70mm 2.8
35mm 1.4
85mm 1.4 of sigma or tamron

and which version? I saw that I can take over the 24-70 mm from someone. But that is the Sigma 24-70 mm 2.8 DG HSM EX version, not the art version. I also saw other versions from Tamron.

Hope you can help me out

For me it would have to be the 85mm............

I agree with Jeff, go for the 85mm

Oke thanks. And why ?

Is there a big different between the
Sigma 85mm f1.4 EX DG HSM Canon
And the Sigma 85mm f1.4 art?
