Thanks, Bill. I had very few clips that I had to discard because of poor focus behavior. I’d say the hit rate for focus was close to 95% overall. Overall PQ (sans the occasional misfocus) & color were 100%. I never had to discard a clip because of color or other PQ issues not related to focus. Unlike previous Panasonic Mirrorless cameras I’ve owned, I was able to have some success with birds in flight in the Wetlands video. For that type of clip there was actually little difference between my A7iii and G9. I found that surprising. Videoing birds in flight is not easy with any AF system.
The majority of clips that did have CAF issues were the result of animals walking behind trees, shrubbery or some intervening object where the animal AF apparently got confused. I also had that occur in shots I tried shooting from a cable car. There the tops of trees would suddenly partially obscure an animal as I pointed the camera down to the ground. I’m not sure any camera could have achieved a high hit rate under those conditions. But even in those cases it was often not an entire clip that was discarded, but only partial clips. So I’d still had a usable clip, only shorter than the original. There were also a couple of misfocused clips that you couldn’t explain, but those were very rare. I also had a couple of misfocuses shooting through dirty glass and a couple using MF. In the MF cases I can only assume I wasn’t reading the peaking indicators correctly.
Bill, I should also mention that just like my Sony A7iii, I also used AF lock in addition to CAF. When you know your subject is remaining a set distance from the camera or moving laterally, I gravitate toward AF lock. I’ve been doing that for years with all my cameras and that’s resulted in an extremely high hit rate. Of course when I can’t predict movement, CAF is the choice and that’s where Panasonic has made strides in the G9. Perfect, no, much improved, yes.
If I was a sports videographer and color was less important to me, I’d still prefer Sony’s PDAF, but the G9 is really quite good. But I don’t shoot sports and overall PQ & color are more important to me. I’ve said it before, but even my Sony would occasionally give me odd misfocus issues, but in a different way than the G9. With the Sony I could have a face filling up 2/3rds of the frame and even with PDAF, it would still occasionally focus on the background. I actually get less of that with the G9.
Knowing the camera and its AF strengths & weaknesses, you can get excellent results with most new cameras.
