Started a new thread for this, as it is an area (timecode!) in which the sound department overlaps with the camera department thus it might interest the camera geeks here as well.

 

Because I got to try out the NanoLockit for the first time, was impressed with its feature in how it can autodetect FPS

 

But Ultrasync ONEs remain my favorite! And the Tentacle Syncs are still handy for DSLR/mirrorless shoots that lack a TC input on the camera.

I'm not sure why it's considered new or interesting to automatically detect the frame rate of incoming code. I've written software that does that in an  afternoon!

I guess, and I suppose more of them will offer this with time, for instance I think the new Tentacle Sync E does this as well?

Here it is, for anyone who's interested!
