    Sigma Art 35mm f1.4 EF and Canon EF 70-200mm f2.8 L USM (non is) are also working good.

    So THC works with redlink protocol directly? YES!!
    Like you wouldn't need fool control? YES
    Does it do start/stop and everything? YES it does start/stop, it does focus and plus iris!
    Also, how hard is it to recalibrate if a lens loses calibration. With the THC you just push the calibrate button

    I use the REDLink Bridge directly with Foolcontrol and the T.H.C., nothing else is needet

    Michael, do you got the WMD also?

    As I understand that one is one of the few lens controllers that can collect focus / iris data and even gyro stuff from camera, no?


    don't know anyone that use those two so very curious to know how they work.

    The THC on weapon and EF glas will be pretty clean. Add lens pull focus / iris and nothing to it. Think RED should market that a bit harder, the price for the THC is not bad considering what it does and that it can be complimented with the WMD that is the only true way of collecting lens/camera data etc.


    What is the price difference between optitron 2 and the THC?

    Edit: Optitron 2 1900USD THC: 2900USD

    Optitron wireless unit is actually in the 750 USD range, so the price difference is smaller.
    But you'd have to add the WMD to get the functionality you (and I sorta) are looking for.

    WMD is 3.950 USD
    And you'll also need a REDlink Bridge according to Mikael L: 395 USD if you don't use it with the WMD.

    Price is on Optitrons side, if you don't want to record metadata.

    What we're looking at is a splitter for the ctrl port, as we need to send and read other metadata over redlink than the Optitron controls.

    Or we can find a gigabit router and use wifi to send camera controls via the ethernet port.
    I wish Red could lower the requirements to 10-100 ethernet. That would open up a slew of possibilities.

    sure.

    would the optitron be able to hook up to that?

    No OptiTron uses its own wireless protocol to make sure that the connection is stable and robust. We don't take chances that could jeopardize production ;-)

    Here are the results of my first tests using the Optitron 2 and Canon EF lenses:

    Tokina 11-16 f2.8: Works flawlessly
    Sigma Art 18-35 f1.8: Works flawlessly
    Canon 24mm f1.4 L II: Works flawlessly
    Canon 35mm f1.4 L: Works flawlessly
    Canon 50mm f1.2 L: Works flawlessly
    Canon 85mm f1.2 L II: All features work, but it seems more "steppy" on huge focus pulls than shorter lenses. For normal pulls, it worked flawlessly.
    Canon 100mm macro f2.8 L: Appears very "steppy" on long pulls, but how often do you do big pulls in macro work anyway?
    Canon 135mm f2 L: Again, appears more "steppy" compared with the shorter focal-length lenses.

    Unlike others reporting above, I had no issues at all with the 24mm and 35mm lenses, which is fortunate, as those are two of my three favorites in the kit!
