Any thoughts on how the 40/2.5 G will compare to the Batis 40/2?
Think it'll be a battle of ergonomics, AF, and good optics vs a more nuanced optical performance here. I'd say the Sony lens has a slight advantage in resolution being that it's slightly sharper wide open than the Batis lens—and while the Batis is sharper stopped down to 3.5 or 4, both lenses are excellent assuming you get good copies. Personally, I'd prize the advantage in wide open performance here, but opinions will vary. In other ways, I'd say the Batis has a slight lead optically: almost APO levels of CA correction, excellent color reproduction and contrast, and while both have similarly crunchy bokeh at times I'd favor the Batis more for being a bit more distinct. In terms of light gathering they're almost identical, both due to Zeiss' firware and due to my own preference for dealing with SA—but at distances of over a meter f2 is usable on the Batis, so slight advantage.
In all other ways, I'd consider the 40 G to be the better lens. It's not over inflated like the Batis, it has no firmware interfering with AF implementation, dual linear motors for faster implementation of AF adjustments, and of course first party AF implementation to really make sure everything works well. Additionally, the 40 G is nearly half the weight of Batis. It has a mfd just 0.01m off the Batis lens in manual focus, but due to the wider effective MFD the reproduction ratio is notably inferior (so, for close focus work I guess the Batis gets another point).
Factoring in price, I'd say there are definitively fewer tradeoffs with the Sony offering in this case, but I guess this can vary on what you value. If I didn't already have the Batis, and if I had an α7C (specifically, double the low light focusing capability of my α7 III) I'd probably get the 40 G and never look back.
