If you check above, the Loxia performed noticeably better towards the corners at most wider apertures (resolution and contrast).
I wonder why you are getting different results and perhaps the culprit is field curvature. If you focus the Loxia 25 in the center of the field at f/2.4, the corners won't look optimal. Field curvature is pretty much irrelevant for the Batis 25 which is pretty much flat at infinity.
There is always the possibility the Batis 25 copy I tested was not optimal even though it was well-centered. However, I've tried different Batis 25 copies and they seem to perform similarly. Here is another Batis 25 copy (my own) tested against the 12-24@24mm: https://www.fredmiranda.com/forum/topic/1523443
These corner results do not look similar to what I get from the Loxia 25.My results were like Fred's: noticeably better corners on the Loxia at infinity. Of course Bronco is not infinity: but maybe it's far enough away to not be different? I guess its possible that the FC on Loxia is stronger a bit closer than infinity?
Every test I’ve run with it and infinity usually gets the same results

Field curvature for the 21 and 25 do increase with distance but I think Big Bronco is already far enough. (25 feet?)
Both Lox 21 and 25's FC's shape is similar where the corners and mid benefit from focusing at the hard stop and the center a slight tad before it.
I do think that if Guy focuses on the corner or even mid, the Loxia would have the edge on these areas when compared to the Batis.
Both excellent lenses and I can see why many folks own both.

I am focusing really outsidecthe center zone which would really be the bottom of the big B

My problem with that technique is it’s not really real. If your going to focus on the corners than your most likely on a tripod and stopping down anyway. I do and also understand focusing out of the central zone but the corners seems a rare time. Also look at the Loxia corners, how much better can it get. It’s damn good as it is. Also are we going to shoot wide open and expect critical corners. I’m anal too but we also have real world shooting to think about.

There is no technique to focus on the corner for real world shooting! In the case of the Loxia 25, it would only make your center weaker.
It's just that when comparing the edges from lenses side-by-side, the lens with less FC will usually benefit. If you focus both on the corner, we would clearly see which one does better since the field curvature variance is removed.
Having said that, with the wider Loxia lenses and many others with similar field curvature shape it makes sense to focus the scene at around mid-field instead of center in order to achieve great resolution across the field.
That's one of the benefits of the Batis 25 where one can focus anywhere and still get similar results across the frame.

Depending on your subject, field curvature can be either friend or foe.

Interesting. I was getting better corners with Lox at infinity than (well centered) Batis, even though both were focused at Centre.
Maybe you have a Golden Batis? Or a less great Lox than some? (Perhaps my Batis is a tiny bit less good than some, but then Fred got similar results with multiple copies...)
Anyhow, both are great in many ways, and I’m keeping both for the foreseeable, though Batis will go if either does...

p.2 #9Loxia 25 VS Batis 25mm Big Bronco
I do think I got a really good Batis. My last one I would have remembered if the corners where this good. I do have a good Loxia as well. I think the Photo Gods might have been smiling on me here. I do think the Loxia is ultimately better. I’m just a little surprised the Batis is really hanging with it. I’ll use both as well. Batis is a little to big for me in my PD sling 5. The Loxia fits nicer. I do want to test this some more and I’m not thrilled with the CA either. That can be somewhat a issue.
I’ll post some more when I get the grandkids down for bed. I did some bokeh tests and a CA test. I’ll load more Raws too maybe you will see something I don’t.

Guy,
I just downloaded the RAWs. Thanks for posting. Did you notice that the Batis has deeper colors?

Also the Loxia samples are getting some mechanical vignetting. Did you use the OEM hood or something different?

Hood is me , so ignore it. Ill put the OEM hood on.

So folks the Loxia has a metal screw in hood and causing technical. So ignore the vignetting on it. Not there

At F4 everything is equal but there is still CA in the light fixture on the Batis.
