r/Ronin4D

Just bought the 8k and only have the 17-28 DL-mount but have seen conflicting reviews whether E-mount or L-mount works best. Considerations:

- resale: investing in DL mount lenses seems like a poor choice. It's a small ecosystem and selling later seems problematic

- lens swapping: I know that if it's time-consuming/finicky to change a lens (with mount+lidar+calibration etc) I'll probably just leave the one I have on and "deal with it"

- general compatibility: I've heard L-mount can work natively eliminating the need for a focus motor. I've seen lots of reports of focus hunting or unreliable AF on some lenses

- character: DJI lenses seem a bit pricey for what they are. The Viltrox set looks like a decent budget option but apparently also "get the job done" without a ton of character

- price: looking to spend somewhere between $1200-$1800 CAD per lens ($900-$1300 USD)

The general plan is to keep the 17-28 for now and add a 50mm + something in the 70-85 range for now but down the road I'd love to just commit to one mount if there is a "best" choice. Any help would be HUUUUGELY appreciated! 🙏🙏🙏

Good options I've seem come up a few times: sigma art series lenses but some need counterweight (not sure how annoying that is), Panasonic f/1.8 Series, Thypoch Simera series but open to other options based on others' experience!

I’ve been shooting on the Ronin 4D and recently rented the DJI 17–28 DL lens. I honestly loved how simple it was. Just slap it on and go, autofocus worked without any headache.

Now I’m looking at the Viltrox Raze f/1.8 DL lenses, but I can’t find anywhere to rent them. I’ve seen a few YouTube videos but they’re basically just an advertisement. Has anyone bought them and put them to the test?

For context, I’m coming from Canon and used my 50mm f/1.2L with the 4D. I’ve tried calibrating it multiple times and have had some success but focus just never feels reliable.

Basically, I don’t want to use the focus motor. I know this limits me SEVERELY. And I don’t want to need to calibrate the focus because I haven’t found real success using my canon 50mm.

With the limitations I put on myself, am I basically stuck with DJI’s DL lenses for that kind of reliability, or are there other options (like Viltrox or anything else) that actually deliver?

I’m a One man band for last 15 years in regards to camera help.
So i’ve been runnin Sony 24-70mm GM II and it’s the best lens i’ve used that almost nails the AF all the time. Bloody heavy though. It’s The best at 10metre distance too which is why I bought it.
Then I borrowed a friends DJI DL 50mm & WOW 🤯, absolutely nailed the auto focus perfectly.
So my question is, what do they look like? I’m a good colourist, and I’m sure lenses are fine for corporate videos, I probably wouldn’t use them in a feature film. But can someone change my mind?

I’m honestly blown away by this one.

I lost a tiny nut on my Ronin 4D follow-focus motor, this one :

the kind of part that:

• is clearly user-replaceable
• comes in multiple sizes in the original kit :

So I contact DJI asking for a replacement.

Their answer?
They refuse to send the part.
Their only solution: ship the entire motor to a repair center.

Let that sink in.

A professional cinema camera system… grounded because of a missing nut… and the manufacturer won’t send a spare.

Their justification is “safety and performance standards.”
But somehow it’s safe enough for users to swap these parts themselves out of the box?

In reality, this means:

• downtime
• lost contracts
• shipping delays
• all for a 2-second fix

This isn’t just bad support — it’s a complete disconnect from how professionals actually use their gear.

If DJI positions the Ronin 4D as a professional tool, basic spare parts should be available. Period.

Anyone else dealing with this kind of policy from DJI?

Meanwhile I'm managing to shoot with this kind of shitty rig, Bravo DJI !

thinking about picking one up and curious if my current set of lenses would even work on the camera.
