I like the MF on the 24 GM a lot better than the MF with the Batis 25. Works quite well in a MF kit!
This ^ ...and I know some photographers who would choose the GM over the Batis just because of it.
The 24/1.4 GM's linear focus by wire MF does not match helicoid MF lenses like the Loxia 25 but it's reliable and enjoyable to use.

Above the star, a metal band runs left to right, fascia, or something like that for the roof. On my
monitor it looks like a purple line on the top edge of the metal band.
Just me? My monitor? The way the band is supposed to be?
No biggie I'm, a dose of defringe to help possibly?
Remember I do mostly wildlife so have curiosity but little knowledge.

Could anyone test this lens against Batis 25 please? Of course, if you have both. Thanks
I finally had a sunny day here in SE PA where I could go out and I did a little testing with my 25mm Batis and compared it to my new 24 GM and I discovered that my Batis is decentered, and my GM is damned near perfect. I can't compare to a perfectly centered Batis, although mine is not terribly far off center--just one corner is softer. That said, the GM is just stupid good wide open, razor sharp in the center and very, very good in corners. The next closest fast prime I've used was my Leica 24/1.4 Summilux back when I shooting the digital M system, and it had more LoCA/PF than this Sony has.
Some crops to show corner-to-corner sharpness near infinity, wide open. Straight from LR using the Camera Standard profile, no lens profile or CA adjustments. First the full view, then the corner and center crops.

I have noticed a little CA and some LoCA. I shot a cigeratte pack on the image thread and you can see the LoCa.
We certainly need to test more for stuff like this. It’s not perfect but it’s far better than many thought it would be.
I do think sometimes we expect too much from a 1.4 lens as it’s damn hard to correct the CA stuff. The really good news here though it’s very flat field and has very low distortion. Sure it may not have the greatest sun stars or flare control as maybe the Loxia 25 bit for a GM it maybe the best yet considering all the factors.

To answer the top band it is metal and I’ll look again but probably some CA at F2.
Wide-open there is a ton of CA with the 24/1.4GM. (lateral and axial)
Nothing out of the norm for a fast 24mm lens though, especially considering its size.

I did shoot those white lettering on that one building I always shoot but only noticed CA at 1.4. We do need to test in more detail for stuff like that for sure. I do use caution saying that though it is a 1.4 lens and we need to expect some of that. I’m going to go out and test the classic CV 35 and I’m bringing the Sony and Loxia with me too. Together we will figure this out

No worries. Guy, you and the bronco show my wait will be worthwhile.
You've had a long day I'm sure, but if say going outside for a Marlboro break maybe point
it toward a star and use AF. I think Albert Dross said actually focusing on a star is easy
with the 24/1.4. Don't quote me exact on his wording.
Your test show it is more capable than I am. What I'm happy about is the weight.

Also glad to hear the fly-wire focus is better than the Batis. Reason I sold the Batis 18mm and added the Loxia 21.
I'd bet after using the 24/1.4 I'll dream of an FE14mm GM. Just think, no coma and flat field. Be a reason to tip back some vodka

Im pretty damn shocked its so close if not exceeds the Loxia here. Sunstars and flare maybe a different matter but this thing is good.
Im loading Big Bronco Raws now folks so you can compare on your machines

These must have in camera corrections It is the only way you won't see the CA and light fall-off wide open. As Fred note's below your post Wide-open there is a ton of CA with the 24/1.4GM. (lateral and axial). It is not showing up in your images so you must have a very special copy of the lens, or these is some correction going on somewhere.
I notice my JPG's look pretty good when I turn on in-camera CA, vignetting, and distortion correction. Maybe a better job than quick LR processing of the RAW file.

Exceed the Loxia? Where do you see that? For me contrast and sharpness is better with the Lox, brightness (vignetting) is better with the GM.
If not exceeds is a figure of speech but as you said it does in certain areas. I did not say everything. I even went on to say sunstars and flare is a different matter. Distortion the Sony wins that round. It’s pretty obvious
Does anyone really expect it to pounce the Loxia. BTW I own both and paid full price for both of them. I might sell my Loxia so this does not help in that vein either.
I also went on to say this

Indeed. But no more than B25 wide open, and less than B25 when both at f2
As you say, plenty of CA at wide de apertures but still great performance for a fast wide.
In fact I’ll say it’s (so far) the best fast wide. But people seem to expect perfection.
But you only find (near) perfection in short to medium tele lenses.
A few years yet before the best fast wide is also ear perfect.
But seriously, this is **so** much better than classic fast wides.
Of course the fact that it’s the best fast wide is not a reason to buy one unless you need a fast wide. I worry that some folks get so xcited about how good a lens is they don’t think about whether they need it.

There maybe a downside here and need to look for it. But these faster lenses tend to defract a little faster too. So it’s possible at F8 it maybe going the other way and landscape shooters don’t like there DOF being shortened. I have not looked into this yet though. Need to study my raws more

David have you seen anything yet on it
Hi Guy,
Isn't it usual that the lessening of sharpness and diffraction of faster lenses normally begin before they do on slower lenses (it is in part determined by how many stops closed down from being wide open)? That is one of the reasons that often slower lenses tend to be better than faster lenses for landscape work and apertures of about f8 and possibly f11.
It is the only way you won't see the CA and light fall-off wide open. As Fred note's below your post
