I have original C100 without autofocus upgrade, I would like to use the C100 on a Ronin M with the Tokina 11-20. I would be renting the lens and Ronin M with the Cinemill extension rods. Does anyone have experience with this setup? Pitfalls? I will be using this indoors capturing people and wanted the benefits of the wide angle (15-20mm) along with the 2.8 aperture. The shots are going to be quick.

Thanks Roy
 
Ok. You'll need to remove the grip for it to fit. Also, when balancing you kind of need to do it in steps - the height of the camera requires you to take it off the mount, then reattach it on the vertical position to balance the vertical axis. After that, take it off again and reattach in the horizontal position. Besides that, it works pretty well. Don't try briefcase or inverted mode as the camera hits when changing positions. I've ised 11-16mm and 18-35mm on the M with no issues.

Could you show any video how is it working all together ( C 100+11-16 , 18-35 )

I've used inverted mode before with C100 MKII. It does hit, but it goes back to normal once upside down. It worked.

I had some problems though with the Ronin (not in inverted mode) : on the footage it's like having the sensation of the steps while I'm walking, its very weird, and kind of disappointing. I'm pretty confident about my balancing as I've successfully used Mövi M5 and Besteady before, with no problems. But with the Ronin, I always experience to see some wavy footage. Like seasickness footage. I've tried a lot of configurations for the motors strenght, used autotune or tried different manual configurations....

The power always show me values between -3 and +3 so I'm guessing I'm balanced right.

Tried different deadband and accelerations configurations as well....always the same goofy results.

Am I the only one ?

I had this problem as well until I actually tightened down the screws with the included wrench on both the vertical and horizontal axis. Once I did that it was smooth sailing.

I tried to position the C100 so it just barely went through without hitting the EVF. It worked at the end, but I only tried it one time. I guess you`ve done it more than once: Are you saying that ideal balance is only gained, when the C100 is positioned so it can't rotate back without hitting the EVF...?

thanks for the advice. but weird though, because I remarked that the screws wasn't always tightened well, so I always tightened hard all of them..and still got my problem :/

+1

Although I'm not sure about briefcase mode not working, but I turn it off anyway.

Also, obviously, you can't tilt up too far as the lens will hit the cage. And you will need the extension arms and a very lightweight wireless FF.

Sorry for the late reply. The weight of the lens determines how far forward/back the C100 sits on the plate, and therefore if it hits the back or not when tilting up. A very light lens like one of the new STM primes would probably work great. Since I'm using heavier lenses (11-16mm & 18-35mm) the camera has to sit back further to balance and it limits the tilt both in operation and when balancing.

Also, as it's been noted by others, it's not that the briefcase and inverted modes don't work - I've just had some PITA moments when the camera or cables hit during the transition requiring a reset. For me it's not really worth using these modes on the fly as the transition isn't all that consistent. For a specific shot where you're not taking the camera out of the inverted or briefcase modes all that often, I'm sure they would work fine. I was speaking from a run-n-gun perspective on using the Ronin-M. YMMV.
 
I recently bought the Canon 10-18 STM IS and was amazed at how light that lens is, it's like it is made of Balsa wood as far as weight. Seems to be built okay although it is plastic mount. I bet it would be a good choice for the Ronin M?
