The 21mm just does the others here. The dun coloured grasses are just that, not some dirty magenta toned mess, the highlights are higher, the greens more green and all colours better separated, colour tones show more grading. I'd be resigned to a lot of PP for the new 25mm going on these images, starting with a significant WB fix - bright daylight is a harsh test, but exactly the kind that should favour Zeiss.
The Nikon does quite well here, and under-exposure handicaps the 25mm. It (Nikon) certainly has a weak colour response (also seen in the night shots earlier on), but at least it shows UV correctly, has clean colour..despite poor separation, it provides a better starting point. thanks to Wayne.
Thanks Phillipe_pj for your excellent analysis. I agree the nikon doesn't tender good tonal separation in the tree leaves like the 21.
I would just like to mention that I used daylight LR WB setting for these last comparison shots.
Can anyone tell me what a good CA removal setting for the 24G shots in this last comparison?
LR didn't seem to improve it any when I tried it.
Wayne, 'Apparently' the new LR4 is better for CA removal, from readings...I have only a few lenses that require much of it, but I don't find ACR6.5 (LR3) entirely satisfactory, doing it manually.
The profiled lenses seem to come up quite well, but not many profiles for CY lenses, or they are not quite what I want in other areas such as the distortion 'fix' for the CY 21/2.8.
Maybe there is a good one available for the 24G? Maybe the folks over at Nikonians can help? Most of what I see in the 'torture tests' here is green/magenta, but ACR/LR has blue/yellow sliders..and it seems to work at cross purposes. It's pretty fiddly too, I am probably not good enough at it, lack of practice, lol.
On Sony, I use daylight WB for all such shots - it seems to work fine for general use, and I am guessing Canon should be the same. Still cannot get over the differences in these images for colour balance...Edward K has talked about warm ZE lenses but this 25/2 looks well, almost extreme, for this content.
For those subscribers out there, Lloyd Chambers just posted his first head-to-head of the ZF.2 2/25 vs Nikkor 24/1.4 @ ƒ/2. The results on this infinity comparison favor the Nikon; central & corner sharpness + vignetting control are better while the Zeiss wins a nod for superior color correction.
My subscription ran out awhile back.
Curious if he spotted the smeared extreme corner?
The 25/2 shots on his blog look very contrasty like my middle of the day shots.
Does he say if he thinks this is due to some field curvature?
I did notice that his blog shot shooting down from Hoover tower seemed ok in the corners which follows what I found, that if you tilt the camera down a lot so distant hills are covered in the top corners, then the smearing in bottom near extreme corners lessens a lot.
Although 24G is pretty good stopped down, I would have thought the 25/2 would have beaten it in the resolution testing.
It's mentioned elsewhere but not yet addressed in this comparison. Even to f/8, the far corners on the Zeiss are smeared whereas for the Nikkor, corners are perfectly rendered by f/5.6 and only soft in the very extreme last 1mm or so of the frame at f/4. Mind you, this first set is at infinity focus for distant subjects/cityscape.
philippe, that is some vignetting...from this image it appears you see it in the long edges as well as the short edges. The subject is very nicely drawn, and colour looks good.

G. Pierre, I would like to see some tests done at longer distances - landscape vistas, distant trees, mountains, whatever, which might reveal any softness in the cornes and image side borders. This is where the weakness has been shown previously with the 25/2 even stopped down.
cyra, Lloyds does have at least one test of the 25/2 at a much further distance than 1-2m that showed the weak corners stopped down if I recall (I no longer subscribe).
Well, already It is expanding the test complement with two new series. In this case locating the motive in and angle, APSc zone and center and a distance of 700 meters and other near of one km.
I repeat that I have not seen any problems of sharpness in corners zone on motives approaches at infinity. I´ve seen clearly problems when the focus is not done well.
G Pierre, my copy of the ZE 25 f:2.0 also shows softness. But there may be confusion due to the fact that it is only in the extreme corners, not the whole corners. Does that help?

No Philber, I have no problem of lack of sharpness in corners. I have been the tests only to show the results because that there some users that report problems of this type. My unit works great.

Phillipe, good to see you got your lens after all. Congratulations! So, how does it compare to the 35/1.4 and 21/2.8? Rendering, colours, contrast... is it a worthy lens in between these two?
thanks for the extended test, German. The inifinity corners look good in your images. But: the last tip of the corner can't be judged, because there is sky and no structure.
It would be good to place the buildings further into the corner, so that structure is covering the whole corner.
also in some images the magnification does not show the exact close corner, but a part slightly up or into the image, where there is no problem anyway. People here are talking about softness only in the last mm right in the corner. It shows in your sample 3 (100% of the ground cover) and 6 (100% of the ground with leave).
It would be nice for someone to also compare it to the new Samyang/Rokinon 24mm once it's in larger release. Especially to look at the corners. I have the Rokinon 35mm and 14mm and they both have very nice corners.
