Some 24 mm comparisons [Nikon/Sigma]
I still don't know if that comparison would be better placed next to the threads for Sigma 24/1.4 A. But since I compared Nikon with Sigma lenses, I thought the Nikon forum would be the right one.


What I did was very unscientific. I wanted to know, how bad the "weak" corners really are. I didn't use a chart for that but a fence which had a lot backlight and some structure in it. Also a good indicator for nervous bokeh.


I compared those lenses:
  • Sigma 24/1.4 Art
  • Sigma 24-105/4 Art @ 24 mm
  • Nikkor 24/1.4 G which I used a lot
  • Nikkor 14-24/2.8 G which I also use a lot
Camera was D810 on a tripod. I turned it, so the top tube of the fence made a diagonal. Camera was not parallel to it to get an idea of the bokeh. I always used LiveView to focus the left corner and the center. So there's no problem with field curvature, I was just interested in the difference of sharpness  between center and left bottom corner.


Here's the whole picture

First the centers of the fast primes wide open.

Then the Sigma 24/1.4 Art @ f/1.4

To me, the Sigma has a little bit more sharpness and contrast. Now let's take a look at those nasty corners.

Of course, no auto-correction of CA involved, otherwise it would be a little pointless. If it's doing alright at f/1.4, I was curious how my other 24 mm capable lenses would do.

Now it's zooming colleague 24-105/4 Art (so that's wide open for that lens)

And least the 14-24/2.8 @ f/4

I don't want to bore you with all center and corner shots. Anybody interested can see for himself: 24 mm comparison gallery I know, it's not very comfortable but the EXIF-data is included and I tried to give the filenames a little bit of sense.


Probably I'll add some night-shots before I sell the Nikkor 24/1.4 but I don't expect dramatic surprises.
