RED TECH | DSMC2 Back Focus | 4K

*Reminder: All RED cameras come factory calibrated. Back focus should only need adjustment if you detect inconsistencies.
This RED TECH will cover back focus adjustments on the DSMC2 brains. Back focus, when properly set, will ensure that the marks on your lens line up perfectly with the distance to a subject from your camera’s witness mark.
When assessing back focus, there are two things to consider-- the lens and the camera’s flange depth. This process of checking multiple lenses helps to verify if the camera requires adjustment. If one lens out of the set is off, it may need to be shimmed by a lens tech. If coming up short, increasing the distance between the sensor and the front flange might fix it, and if deep, try to shorten the distance. Turning clockwise will pull the sensor closer to the front flange, and counter-clockwise will push it further away.
RANGER brains do not have the ability to adjust back focus. Please speak with a dealer or rental house if there are concerns.

The RED Focus now are not recommended ? We have The Red Focus for back focus adjustment ....

[@JonWolf]

My camera has stopped focusing to infinity. Do i need to fix the back focus ?

[@KakiChaitanyaDeep]

May be, you can use Focus Peeking to make this faster.

How many lenses I have to test for each set? My CP2 15mm, 25mm and 35mm perfectly match with chart.. But the 50mm not, why? If I move that screw of the sensor will change the back focus of other lenses!

[@alexandremichiels3594]

then it is your 50mm that is off, you need to get your lens shimmed at a rental company. that mean that instead of changing the distance between the mount and the sensor you will change the distance where the lens is creating the image (where the light meet). And that is done using shims which are tiny disks of metal that you add under the mount of your lens

@@alexandremichiels3594 thanks for your detailed explanation, as I expected I have to buy these disks

Overpriced SSDs

Why are these videos never recorded at 60 fps? Whey are they never encoded in HDR? Why???

Budget costs

HDR on a RUclips video where no one is watching in HDR because it's a computer screen. That's why.
