Sirui Nightwalker 24mm T1.2 S35 Cine Reviews
Great for low light, especially on a budget!

I waited a few months before I wrote a review. I currently own the 24mm & the 35mm lenses of the nightwalker series. Great in low light or any other occasion. Here is what I have noticed specifically for my camera.
Panasonic Lumix S5:
White Balance in Kelvin with these lenses. They do not perform well in the AWB or the presets from the camera.
If you are shooting during the day with them and you are used to overexposing due to file format (VLOG/SLOG/RAW/etc..) dial it back. These lenses really open up. Be mindful of the T-Stops especially if you are hand holding it. The ring intentionally fluid and can be easily moved from your intended image.

Since this is made for APS-C cameras, would there be any crop factor if this was shot on the FX30 (so a 1.5x crop factor)?
Asked by: Blake
When using the Sirui Night Walker 24mm T1.2 S35 Cine Lens (E-Mount, Black), it would still be 1.5x when using the FX30. Even though the lens is APS-C and Super 35, the sensor crop factor remains. The 24mm Sirui lens will look like a 36mm view.

Asked by: Jason
No, all of the lenses from the Sirui Night Walker line, like the Sirui Night Walker 24mm T1.2 S35 Cine Lens (RF-Mount, Black), are made to cover Super35/APS-C Sensors, and will vignette when paired with the Canon EOS R5 C Mirrorless Cinema Camera (BH #CAER5C).
