As you may know, the new Sigma 14mm 1.8 was just released, and I was lucky enough to get my hand on a production copy. As of now there is not many real world shots to find for this lens, so I thought I might help you guys out a bit.
All shots are taken with a Canon 5D Mark IV. At the end you can find a download link for the full resolution jpgs (exported from Lightroom with no adjustments) and the raw files.
Lets start with astrophotography, since it seems everyone is asking if this lens is suited for it. All shots taken at f 1.8, around 15s exposure.
So far ok, the lens works. Another one:
Detail from the top left of the frame:
I guess it's ok for f 1.8. One more with detail top left and top right:
Honestly, I found it hard to focus. When I focused in the middle of the frame, the corners were worse than that. And each corner seemed to need a slightly different focus to get optimal results. In the end, I am not qualified enough to give out any judgment, but feel free to download the full resolution jpg and raw files at the bottom of the page.
Lets continue with a shot wide open at f 1.8 and 1/8000s exposure:
Then the same shot with f 5.6 and 1/1000s exposure:
While not the best shot to measure actual vignetting, for me it was more about finding out if it feels too distracting or not. And I am quite pleased. In any case, as soon as the profiles are out we can of course reduce the vignetting in post.
Next I want to look at Bokeh. One use case I intend to use this lens for is environmental portraits at weddings. I focused on the little wooden owl at a distance of about 2m (the closest i can imagine doing an environmental portrait with this lens). As expected with 14mm on fullframe, the dof is not that thin:
Take a closer look:
This looks perfect for my intended use case: the background is only a little bit blurred, but very smoothly.
Let's look at Flaring:
If you would like some other test shoots, don't hesitate to write me an email. This evening I will try to do some astrophotography. And then the next two days I will shoot an event where I hope to get some shots with this new lens.
