Thanks for the wonderful response!
@baldavenger I am amazed how much color data is captured! Alexa's sharpness is the last big visual advantage to tackle (comes out really soft on the 5D Mark III) so no 4K for me yet.
@Pedro_MOD yep, right at 23.976. I did slow-mo the second-to-last clip to 65% as a few boundary frames were corrupted, but everything else is at native speed (everything was shot at 24fps)
@beauchampy polarizer filter makes night + day difference — I wouldn't travel without it! It cuts out so much haze, unwanted reflections, etc. For video, it has the added advantage of cutting out light so I can shoot at the slowest shutter speed.
@DeafEyeJedi the 24-105 is unfortunately soft (I've been spoiled by the 70-200) but its logistical usefulness is hard to beat! I used a 4-node setup to convert colorspaces, make RAW adjustments, then applied one of the built in 3D LUTs in Resolve (I can't remember off the top of my head, I'll post back). The 3D LUT really helps with color contrast, as the footage comes out with a really flat color spectrum.
MLVFS made doing an initial grade on-the-go much easier. Still a kink to work out with load time (I have to wait 5 minutes for Resolve to generate thumbnails on load) but much better than running mlv_extract for hours just to see footage!
