You considered trying the Samyang? I kind of wish I kept my Sigma and I'm tempted by the Samyang, but the Sony 85mm is just hard to get rid of as it's so good.
I'd definitely get the Sony if that's the case.
I'm resisting the urge to change all my gear. After getting the 16-35mm GM, I feel like I'd be better off with the 24mm GM and selling my FE 35mm. I might rent the Sigma 24mm for a few days to see how I like the FL.
I’m going round in circles too (what’s new!). I’ll check out that Samyang
