I spent the last 2 days finding the 'In-Camera' look that required minimal colour grading for an upcoming project while maintaining a compact camera package. The test was conducted with the Sigma FP. The only changes I made to the camera body itself were adding a battery grip that supports 570 Sony NPF batteries and attaching the Sigma LVF-11 LCD View Finder.
The footage is 12-bit 1080p Raw, recorded directly to an internal SD card. I set the white balance at 5500K.
I shot the Sigma FP two to three stops underexposed, using the base ISO of 100. I find that using EL Zone keeps both highlight and shadow information intact.
The lenses I used were the ZEISS Biogon T* 2/35 ZM and ZEISS Planar T* 2/50 ZM. Both lenses were designed to work with Leica M cameras but are easily compatible with the SIGMA. One concern I had was the possible colour cast that the 35mm might produce due to the proximity of the rear lens element to the sensor.
Upon reviewing the graded screen grabs, nothing stood out negatively.
I find that the images produced with the ZM lenses and the Sigma FP at 1080p have a pleasant softness and closely capture the essence of the project. I'll be editing a montage of footage taken from this test and sharing it shortly
Nice love this idea, does this approach have any negatives to DR flexibility in post?
