6K Sigma 18-35mm f1.8 DC HSM | Art Lens with BMPCC6K Night Shot in Miyagi Japan

F1.8通しシグマ Artライン 標準ズームレンズ Sigma 18-35mm f1.8 DC HSM|Art Lens with BMPCC6K 暗所撮影レビュー

I attached Sigma’s art lens 18-35mm f1.8 to the Blackmagic Pocket Cinema Camera 6K made by Blackmagic Design and took a test shot of the night view and illuminations of Sendai Japan.
Since it is a replacement camera from the Sony α7S, which is strong in the dark, I am a little dissatisfied with the high sensitivity performance, but compared to the early S-Log2, the Bracmagic RAW Film is completely different in detail and color beauty.
Since the Blackmagic Pocket Cinema Camera 6K has selected the EF mount used in Canon SLR cameras, you can use the EF mount lens whose price is starting to drop in the second-hand market and the EF-S lens dedicated to APS-C.
However, EF lenses are still expensive, and I felt that the resolution of EF-S lenses was low.
I had been considering purchasing a new lens while looking at the lens comparison site, but I bought the Sigma 18-35mm f1.8 Art lens, which I felt had a high resolution and a good reputation.
The Sigma 18-35mm f1.8 Art lens is a large-diameter standard zoom lens designed exclusively for APS-C, and boasts the world’s first open F1.8 overwhelming performance among zoom lenses dedicated to single-lens reflex cameras.
Blackmagic Pocket Cinema Camera 6K uses dual native ISO based on ISO400 and ISO3200.
Native ISO400 can record in a high dynamic range of 13.4 stops, but ISO3200 with high ISO base sensitivity will record in a dynamic range of 12.1 stops.
ISO1250, which switches the base sensitivity, has the advantage of less noise than ISO1000.
However, if the dynamic range is narrowed by more than one stop, there is a demerit that, for example, the illumination of a point light source and the stars of fireworks are likely to be overexposed.
With the Sigma 18-35mm f1.8 art lens, subjects previously shot with a base sensitivity of ISO 3200 can now be shot with a native sensitivity of ISO 400.
Therefore, it will be possible to shoot images with less overexposure even under conditions where bright light enters in a dark place.
BMPCC6K ISO4000 and above are often too noisy to be eliminated even with noise reduction.
Even if the noise can be reduced to some extent, the details may be crushed or the banding may be noticeable, but using the ISO sensitivity one level below makes it easier to finish the image with less noticeable noise.
This lens has some areas where ghosts are a concern, but you can clearly see the difference in sharp resolution and high contrast that projects even fine lines.
Until now, I used to apply color grading based on the Buttery Natural LUT and Emotive Color P6K Alex, and I used to make color corrections completely original.
However, I think that the color comes out firmly without increasing the saturation or adjusting the Tone curve.
The Sigma 18-35mm f1.8 DC HSM ART weighs 810 grams and is recommended for those who don’t mind the lack of built-in image stabilization.

6K Sigma 18-35mm f1.8 DC HSM | Art Lens with BMPCC6K Night Shot in Miyagi Japan

0:00 Night View from Sendai Castle (Sendai City Miyagi Prefecture Japan)
After shooting with a base sensitivity of ISO3200, color grading was performed with DaVinci Resolve.
I am using f1.8, but I am shooting with the shutter speed reduced to 1/33.
High-sensitivity noise was noticeable, so I used Neat Video to perform noise reduction processing, but even if there is no problem with the exported data, banding is inevitably noticeable when uploading to YouTube.
Luts used Butterfly Natural Luts.

2:12 Sendai Pageant of Starlight in Izumi Park Town (Sendai City Miyagi Prefecture Japan)
With conventional lenses, it was easy for buildings to appear dark unless they were shot with a base sensitivity of ISO3200, but because the dynamic range is narrow, the point light source will white clipping.
By using the Sigma 18-35mm lens and using ISO 1000, which is the maximum sensitivity of the native sensitivity, I was able to record video with less black and white clipping.
This is because the BMPCC 6K uses dual native ISO, so the dynamic range is switched.

3:32 Sendai Matsushima Rikyu Pageant of Starlight (Matsushima Town Miyagi Prefecture Japan)
The Christmas light event started in 2020, but this year the variety of colors and brightness has increased, and 3D projection mapping has also been carried out, making it even more spectacular.
I used ISO1000 for shooting in this scene as well, but I was able to restore the color of the slightly overexposed areas with the highlight recovery of DaVinci Resolve.
This scene is mainly color graded using the Buttery Natural LUT as a base.
However, when the light was champagne gold, I was worried about the color cast of the shadow, so I used Gen4’s color science to adjust the color with the color wheel and hue vs. hue curve.
I was surprised at the beauty of the bokeh of the background when shooting with F1.8 using the maximum telephoto 35mm, but I also felt the severity of being out of focus even if the standing position was slightly off.
