Sigma 85mm f/1.4 ART vs Samyang 85mm f/1.4 vs Tamron 85mm f/1.8 VC
Thanks Klaus! Now it's pretty obvious why I'm considering the Tamron and the Samyang, but not this Sigma (if the old EX was sexy, this one is... BBW in comparison.
) If the stars are finally aligned, your tests of these two will probably will be the last argument in favour of one of those two.
I have no idea. What Sigma thought when they made it that big. Or what BBW is (maybe I don't want to be enlightened). The 85 of Sigma was no easy choice for me, but having tried the Tamron after there's no regret I went for the Sigma. At least it's sharp. But it wasn't out of the box.
The Tamron, at least wide open, shows a kind of overlay. It focussed mostly well, but at f/2 was a layer of softness which I don't see in Sigma's wide open frames. It has a nice bokeh and is definitely more portable. Couldn't try in low light, because here's a challenge, Sigma often fails at the outer focus points. At least since the last firmware update of the D850. Suspicious...
It look likes MTF bars :-)
Now seriosly
Every design has constrains and priorities.
- price
- size
- materials
- IQ
Just to name few of them
