DJI RS3 & RS3 Pro Bring Autofocus to Cinema Lenses

PostWed Jun 15, 2022 9:49 pm

So DJI has managed to bring autofocus to manual cinema lenses with their LiDAR system paired with the new RS3 and RS3 Pro. I mean, you could do it with the RS2 as well, but it really shines with this new RS3 system.

Introduction Video:

Review Video:


The Pocket 6K Pro gets prominence in the second review video. I'll be curious to see what Blackmagic does next with their Pocket line now considering this tech. Or even with doing a box URSA Micro type camera.

Blackmagic doesn't need to build their own autofocus into their cameras when you have third party tools like this, and that's really cool! Definitely on my Wish List to get the RS3 Pro to play with in the future.

I ordered a RS3 Pro Combo and wait to order the LIDAR Focus. I am very happy about this technology, so I can use my Blackmagic Cameras as well. I thought about to invest beside in a Ronin 4D 6k, but now this is not necessary.

I will also try to use my 12k on the RS3 Pro. The weight of my 12k is 2.55 kgs, my Xeen lens has 0,9 kgs and my SSD Recorder has 0,3 kg. My V-Mount Batteries will be on the Gimbal. I am very excited to test it out.

Normally I do not like Autofocus or Stabilisation, but some customers sometimes ask for these things, so now I can deliver without investing in a Ronin 4D System. Great JOB DJI.

For me with stabilization I use a Steadicam or Slider/Dana Dolly with the URSA Mini Pro. But I wouldn’t mind a lighter set up stabilization system like the RS3 Pro for the Pocket.

For me I’d love to see an updated Pocket with that 4.6K G2 sensor since the rolling shutter on that was the best. Would be so nice for those fast moving gimbal shots.

Happy for you so hoping it lives up to the promise of a great gimbal. Will be looking forward to real users’ reviews especially with regard to the LIDAR.

I noticed on DJI’s website they talk about using the LiDAR system off the gimbal with just a motor and a battery. I’m very excited to see how this will work

Agree, not sure about the accuracy at various distances, but probably good value. DJI claims 1% up to a point and then 3%. Looking forward to learning more from real users when the dust has settled.

So glad I held off buying a gimbal the last couple times the desire struck me, because this just about seems the perfect jumping in point for me... provided it doesn't crap the bed once it hits a wider user base.

In one of the reviews of the LiDAR focus it was shown that when used with manual lenses there are only set points at 1m and 4m. That’s really not enough for accuracy through the whole range, especially if the subject gets closer than 1m.

Will be interesting to read comments from someone who uses the Preston Light Ranger 2. Different price range and focus workflow but that review would help separate hype from reality.

Let's see what will happen with the final firmware of the Lidar Focus. If you go closer than 1m you alternatively can turn on the focus wheel to correct it manually without turning off the Lidar AF. This is also a great feature I love on the 4D and I am quite sure that it will happen on the RS-Lidar Focus, too.

Honestly, I am hyped, because I am looking for a possibility to have Autofocus for some shoots with my Cinema lenses. I tested the 4D and some Sony Cameras and I do not like the filmic look of Sony Fx3 or Fx6 or A7 SIII. I wish to use it on my Pocket and 12k.

There is no perfect system for all needs in this price range, but much better choices than all before. Depends on what you or your customer needs.

Well, despite the reviews saying there are focus issues below 1 meter the technology is still extremely exciting. Just imagine where it will be in 2 years. Then think about 5 years.

I really hope that the next Blackmagic Cameras take advantage of this third party tech existing.

Looking forward to your tests! Please post some pics if you get the setup working. ;) I too have the 12K and would like to use it on a gimbal. Been thinking about the Crane 3 but prefer the DJI ecosystem…

I worked with the Crane 3s and tried to put the 12k and took some shoots with my 6k on this gimbal, but the Crane 3s is not so perfect and sometimes wobbling absolutely out of control.

I balanced everything; for 10 minutes everything worked fine and then during the shoot the crane 3s was going out of control. Zhiyun tried to help me with this issue, but it does not work, so I decided to switch to the RS2 and it was the best decision for my gimbal work until today.

I hope it will work with the RS3 Pro and my 12k with the lightweight Xeen CF lenses. I will make a step by step video of it.

I'm hoping that the system improves in such a way that it communicates directly with the camera and does autofocus with motor powered lens without the need for a follow focus

Today I built up my rig and yes, it works. The full test I release next week. Believe me, it is a question of counterweights, but it works stable. And yes, it is heavy. The Formfactor of the BMD12k made it a bit difficult.

Here is a photo of the rig - it looks like an adventure.

Rick, the operating method is a good question. (laughing) Bodybuilder can do it by handheld, but for me it only works with a Rig-Vest overhead, the Tilta Ring is perfect for that operation method. As I said it is a small adventure.

I used the Rs3 pro with lidar, BMPCC 4k, and Anamorphic setup using a Kowa 16H and 28mm voigtlander, on this one man solo shot short.
It works fantastic.
Especially when shooting in low light settings where using focus speaking to really get focus is almost impossible.

There is a step in the calibration process that requires the distance from the focal plane to the front of the lidar unit to properly calibrate it. Please see the photo that I have attached
The Pocket 6k doesn't have the focal plane mark ...i don't think the 4k does either...i don't know if the 6kpro or g2 does either. Searching online doesn't help best suggestion i got was in one forum post about using the flange distance from the EF mount specs. We really need BMD to chime in on this. Not having a proper measuring point on a so called cinema camera seems to be a big oversight.

Ah, that. I measured with a caliper from the sensor to figure out on the body where the sensor is. And that's where I measure from. It's in line with one of the three buttons on the front of the body. I think it's the center one. But I'll let you know later this evening.

Support indicates:

The distance from the sensor to the mount is 35mm.

So would this mean if i measured from the metal mount forward and add 35 i would get the number i need?

Well i think i did it right.. I basically did what support said..
Started at the metal mount and then subtract 35mm Should be the focal plane...- then add or subtract depending on if your in front of or behind that point.
