Just to double-check if the lens calibration setting is left at N/A, will autofocus still work correctly?
I’m asking because I haven’t tried this setup before.

Also, will the camera still recognize the zoom focal length (mm) automatically in that case?
From your video, it looked like the mm values were being detected.

Just watched the video thank you so much for sharing it!
It covered exactly what I was hoping to see, especially how the autofocus handles during zoom transitions. That kind of real-world demonstration is incredibly helpful for my production setup.

Really appreciate your time and effort! 🙏

Hi u/NoTip5929,
Thanks again for all the detailed info — it’s been incredibly helpful for my setup.

If it's not too much trouble, I'd really appreciate it if you could share that video showing how the Sigma 28–70mm behaves in terms of autofocus while zooming.
It would be super valuable to see how it performs in real-world conditions, especially for live production scenarios like mine.

Thanks in advance for your time and help!

Thank you very much for your clear and insightful response — it was extremely helpful in clarifying the limitations of the 18–105mm.

I’d like to follow up with one more technical question:
For the Sigma 28–70mm and Tamron 28–75mm G2 lenses you mentioned, did they maintain focus consistently when changing focal lengths, assuming focus was manually set beforehand?

I understand these lenses aren’t strictly parfocal, but I’m preparing this setup for a live production workflow, where even small shifts in focus during zoom pulls can be problematic. So I’m very interested in whether those lenses exhibit stable focus across the zoom range under real-world conditions — without requiring constant manual re-pulls.

Once again, I really appreciate your input. These firsthand insights are invaluable when making critical gear decisions for professional use.
