is it true that the focusmotor has 12mm and not 15mm?

what's with dji?

Hi Indio, are you referring to the Rod of the Focus Motor? If yes, the Focus Motor of RS2 comes with 12mm Rod Clamp Inner Diameter. More parameters can be checked here: https://store.dji.com/product/ronin-focus-motor

hi mindy


yes focus motor, but ALL rods are 15mm!

i have a 15mm road fix mounted on my camera cage (BMPCC4k) for the nucleus nano or tilta manual follow focus.
so the camera can be mounted on my ronin S or on the tripod, monopod, slider, etc
also a manfrotto 323 quick-change system is permanently mounted on the camera, so i don't have to do any balancing when mounted on the ronin S.

what helps me now the upper quick-change plate on the rs-2 if i have to change the rod, because the diameter does not fit.

what was DJI thinking? > yes, not finished thinking!

as well as the record button above and the M button below (?)
and no audio from the raveneye

ask your users before you do this nonsense!!!

the main thing is to send pre-release versions to any youtuber who has no idea about the practice and can't handle these parts.



i am thinking about cancelling an order for the RS2 pro for this reason.

Thanks for bringing this rod situation to my attention. Didn't even read the description of the motor but my B cam setup is pretty similar to your BM Pocket. This forces me to use the DJI 12mm rod.
Normally on my current Ronin S / Pocket Bcam I run the same 15mm setup, it doesn't matter if I use the Tilta Nano Motor with an AC or doing focus myself with the DJI motor. This change forces me to change rods for this switch and I don't like it.
I'll look into this once the unit gets here but this might be a dealbreaker for me. Hopefully they'll consider releasing a 15mm adaptor for the DJI motor.

The 12V outputs are gone too. I used those to power my Pocket 4k from the gimbal. I highly doubt there is a USB-C to 2pin Lemo possibility. The voltage is probably not high enough.
I might need to stick with my Ronin S

yes, this is a shame and also the raveneye will not charge if the RS-2 is charging

@Ssaumlsch
you can go with a dummy batterie, but this is not a recommended solution



DJI, ask your customers BEFORE!

you had the chance to build the best gimbal by far and you blew it : -(

thinking is not only enough from 9 to 5

theses changes are done on purpose ...this is normal dji practice with all their products
product separation is most important
stuff sounds good at first until you realize its limited in use
I am so over this

That's my solution for the 12mm rod fail. I might cut the 12mm rod, is I've got the 15mm rod free.

We have no control over what users tack onto their cameras such as a heavy cage, but we do have control over what we make. A 12mm rod is lighter and smaller than a 15mm rod. The motor ends up being smaller as well resulting in an overall weight reduction. When we designed the RS2, we considered weight reduction as one of the top priorities. The majority of the users are not going to be mounting a 3rd party focus motor. It doesn't fit your needs and that's why there are aftermarket manufacturers that make accessories.

hi paul
all good with less weight

but 15mm is the standard!

same with your lower and upper plate
the lower does not fit with manfrotto,
und the upper does not fit with arca-swiss.

and yes, ask me and other user before!

We know 15mm is standard but we needed to compromise for weight for the mass majority of users who won't be mounting a standard 15mm rod focus motor. As for those plates, there is no standard size. We've tried dozens of Arca and Manfrotto tripod heads and they all range in size. There is no standard exact dimensions for these plates and tolerances are very loose.

Hey Paul, thank you for taking the time to answer our concerns!

I understand your reasoning behind going with the smaller 12mm rod size regarding weight but the few grams saved don't outweigh (pun intended) the cons for the pro users out there. And I checked, you guys put "DJI Pro" on the very nice bag the new gimbal arrived in... ;)

The same goes for the missing 12V outputs - is there any way to make it possible via a software update to enable more than 5V on one or two of the USB-Cs?

I used the old Ronin as my B-cam setup for quick walking shots with a BMPCC 4k, perfectly matching my Ursa Mini Pro G2 as A cam. Yesterday I used the RS2 on a shoot for the first time, today I have another job in the evening and I reverted my setup back to the Ronin S for now - it's just the more "pro" option for me right now.
The saved weight overall made it more enjoyable to work with the gimbal but my Tilta Nucleus Nano motor doesn't get enough power from the 5V USB-C to reliably drive my lenses (and for that matter only the top USB-C works with the Nano motor for some reason).
I know how to balance my setup and the process is much quicker on the RS2 thanks to the improved locks and arms. BUT (!) the resulting footage was less stable then what I get out of the Ronin S. There were slight issues with a wobbling horizon and noticable shaking when operating in flashlight mode - that could be minimized by grabbing the back of the gimbal with a second hand so I suspect it's just harmonics with the motors and can be fixed by software, but I rarely had those issues with the Ronin S and only remember them from using the original Ronin 1.

All in all I can't really use the RS2 for professional work as is. I really hope firmware fixes will come along and you guys can address some of the issues we see right now through firmware updates. As it stands right now I see the RS2 as a pure Youtuber / Influencer tool using a mirrorless camera and autofocus or only the tools out of your own ecosystem. I'm sorry to say and I really wanna like the new Ronin but that is not "Pro" enough for me.

We've tried dozens of Arca and Manfrotto tripod heads and they all range in size. There is no standard exact dimensions for these plates and tolerances are very loose.

But if weight was the issue why not just use a carbon fiber rod? Or make the clamp on the focus motor work 12-15mm instead of JUST 12mm.

TBH, I wouldn't mind so much if the power ports hadn't also been gimped to death. From what I can tell you can't get more than 5v out of 2 of the 3 ports, at least not using any standard protocols. If i trigger QC2 or QC3 I will get 5v, but like USB-PD is not even supported. Why on earth are you guys implementing your own charging standard when USB-PD already supports 5/12/15/20v. What other outputs could you possibly need.

I was really hoping I'd be able to run 15/20v on my nucleus-m when I'm using bigger/heavier/stronger motors.

I love basically everything else about the gimbal, but its really disappointing that there is no means to run external power from the gimbal battery or one of the accessory mounts to then pass through to camera/focus/recorders/etc.

At this point I'm basically gonna have to have 2 wires free hanging (power and hdmi) if I wanna use an external monitor/recorder and anything beyond the lightweight included motor.

Don't get me wrong I totally planned to get a good bit of use out of the RS2 motor cause it IS much smaller and lighter, but there are times when a bigger motor will be needed. It's just such a shame that the Ronin-S was more capable than the RS2 in both of these areas. It used standard rods, it can charge cameras, it can power focus motors at 12v, etc.

I for one am strongly considering returning it even though I like it because such a handicap just seems frustrating and necessary.

One of the easiest ways to reduce the weight on the gimbal is to remove the batteries from the camera and run with dummy/dc plug, even if you ultimately use an external battery to power the gimbal itself, as long as its not part of the balanced weight, then it doesn't really matter. This just seems like poor engineering. Especially when the battery IS a 15v battery so there is no good reason to not support passing the power through, especially with all the different accessories tilta is making, like what use is that counterbalance system with dual TB50 or the advanced ring with places for v-mount / gold mount batteries if they can't power ALL the things?

I have to assume the actual core power lines running through the thing are also at 15v (since they power the gimbal motors) so why not expose that power to the USB ports and massively extend the capabilities of what can be connected?

My thought exactly, thank amnesia!

I emailed with a guy from the German support team, he told me to wait for a firmware update in "the near future". They apparently are planning on raising the voltage on those ports from 5V to 8,5V. BUT he also said 12V is probably not coming because of a "optimized power delivery system", I don't know what that means though.
While not having 12V to power some cameras still sucks, anything above 7V is fine for at least a lot of accessories - my Teradek Bolt XT for example would run on that.

When the Ronin S first released it also had a lot of issues but DJI listened and they came out with a couple of firmware updates that made the gimbal into the best one for my use cases - lets hope the same holds true for the RS2, I'm waiting for the first 1 or 2 updates and give them another chance.

I really do hope the voltage is increased for dummy batteries. Also Paul, that’s a frankly terrible response - I get that some of these comments must be frustrating but your response was text-book what not say to a customer, even when a customer is wrong.

Dummy batteries would need to have a handshake protocol for the voltage bump, otherwise, you plug in a USB-C accessory that doesn't prevent over-voltage and you risk them burning out. Also, you'll get straight responses from me most of the time instead of sugar coating.

HI - what adapter is that that allows for you to connect the 12mm to the 15mm?

The 12mm rod is total nonsense. The weight difference between a 12mm and 15mm rod are nothing compared to the weight differences in cameras and lenses that will go on the gimbal.
Using a 12mm rod is really out of touch with the industry and anything related to where it will be used. Nobody even makes anything with a 12mm rod connection. Nobody. Well, except DJI now.
I guess they expect you to use only the gimbal and nothing else during production. Of course you would never want to use your camera on a gimbal then quickly mount it to a tripod. That never happens.

We have the same concerns. We're attempting to run a BMPCC4K with our RS2, but the inability to power the camera through the gimbal is a MAJOR problem.

We are also having trouble with getting our Nucleus-Nano motor to operate properly when plugged into the RS2's accessory ports. We would have purchased a follow focus handwheel from DJI, but they don't have one that's compatible with their motor, so we were forced to buy the Tilta solution.

On the surface it seemed like the RS2 was a really awesome product, but the reality is that it has MAJOR deficiencies. Hopefully DJI is able to fix these problems in firmware or we're going to have to sell this thing.

You found a way to make that distance. I was so upset when, using the same lens on my bmpcc, the silly small focus motor wouldn’t reach to the most common bmpcc lens.

Can you list what parts you are using to make this work?

Hey! Was just looking at all this as 12mm doesn't reach the focus on Blackmagic and a 24-105. Care to share a few links/products names where yo got that little accessory?
