Q: 6. Can lwz.3 cover whole red weapon's 8k sensor?

A: The ZEISS LWZ.3 does a good job of covering the RED Helium 8K Super35 sensor. If you record in either 8K WS (1.85:1) or 8K HD (1.78:1) mode in the camera, then the 21-100 image circle is large enough to project a complete image, with slight darkening of the edges when in the widest zoom setting. When in the 8K FF (Full Frame) setting, you will see vignetting around the top and bottom of the frame. If you go past 23mm to 25mm, the image becomes quite clean from edge to edge.

Q: 7. Does the tilt lock on the left side allow for low friction to aid in smooth tilts? Or it is just for locking the tilt?

A: The tilt lock can be adjusted to increase or decrease friction and aid in tilts.
