Finally someone besides Arca Swiss, Manfrotto, Cambo, or Benro has made a geared head. Have I just found my next tripod head?
In this video, the movements look a bit "jumpy": https://www.youtube.com/watch?v=ndSjsPFO8W4
Is it just the way he's turning the knob? Are the movements smooth if you turn the knobs slowly? Have you noticed any "play" that people have complained about with the Manfrotto 410 and 405?
I'm inclined to say it's partly the video and partly how the knob is being turned.
I was using the head yesterday afternoon as part of my testing of the Fotodiox M645->EOS RF T/S adapter, with amongst others a M645 Mamiya 210/4 on it (note that I've the Rogeti extender/handle unit in the back, partly as a counterweight.
The roll movement (side knob) is particularly smooth, with only slightly more initial resistance to moving - the rubber sleeves on the knobs give a good feel without needing to grip too tightly. An option to have larger grips for the knobs might suit some people with less strength in their grip?
The pitch control (2 knobs front/back) needs a bit of care with setting the clutch, since this affects the feel of the controls - but still smooth.
Compared to the Benro (which I do like) the Rogeti has lots more levels and is much quicker to level. I was using it with the EOS RP, the (brightened) view on the rear screen shows (red) focus peaking for an up-shifted Mamiya 35/3.5 lens.
For my 5Ds, I've also got their L bracket with 3 (X/Y/Z) levels - I was using this the other day with the Benro head, with a TS-E17, moving location a lot and finding the X/Y/Z levels in the bracket giving me a faster and more consistent level than the single (circular) level of the Benro head.
I've another interior shoot tomorrow and I'm now happy to take the Rogeti head on a paying job where I'll be using the 5Ds and TSE frame with 17/24mm TS-E lenses (as in the video)
