I bought one a7R3 from B&H couple years back. I ...

I bought one a7R3 from B&H couple years back. I always use the Movie mode (AF-C and Wide area) to record video. I did not have any issue until I recorded a falls recently. The issue is the AF-C kept hunting the Focus point due to the wind blow to trees and the moving of the falling water stream so my clip has 'breathing effect'. The 'breathing effect' can be avoided / eliminated by using AF-S and Flexible Spot Focus. I have another camera brand which offers more than AF-C and MF modes in the Movie mode. Do you know why Sony just allows AF-C and MF and disables the others? Thank you very much.
Asked by: George
For most video purposes people want to either track an object or do similar work like you've described of recording a landscape scene. Since you can recreate AF-S with manual focus (focusing on a single point and having it not change) they've eliminated that option. DMF is Direct Manual Focus which is autofocus with manual override which doesn't make any sense to use since you have the other options.

Can anyone with an a7r IIIa verify if one or both of the sd card slots are UHS-II? The Sony web site says they are, but B&H says only one is.
Asked by: Dayle
The Sony Alpha a7R IIIA Mirrorless Digital Camera (Body Only) has one slot that supports a UHS-II SD memory card and one slot that supports a UHS-I SD memory card.

What level of autofocus will I have with a Sigma ...

What level of autofocus will I have with a Sigma 150-600 EF mount using the MC 11 converter. Also, what if I add on the Sigma 1401 TC? Should I just buy the Sigma 150-600 E mount for mirrorless? Lots here. Thanks for any thoughts
Asked by: Mike
From our experience (testing in the store and from many of our own team using this combination in the field), we have had excellent results using both the Sigma 150-600 Contemporary and Sport with the MC-11! Using the 1.4x TC did not cause much of loss of speed or reliability EXCEPT that at 600mm the minimum aperture was f/9 and we were not able to autofocus at all, but only with the TC. The lens was able to focus past f/9 without the tele-converter.

what's the difference sony a7r iii or sony a7r iiiA betwen?
Asked by: Mari
In terms of performance, the A7R III and A7R III A would be the same. The A7R III A would just improve upon the original A7R III in terms of its LCD resolution and faster USB 3.2 port.
