Used Nikon D90 for a long time and decided to give this a try. I didn't want to spend anywhere close to $1000 for camera body for a hobby and wanted something more compact to carry. You can use a most of F mount lens with the adapter from Nikon, which was one of the major selling point. Having the floppy screen was great, as it allowed me to position the camera in any direction/ vantage point that I couldn't do with tilt or stuck-on monitor. This is same advantage over using the smart phone, plus you get much better picture quality.Picture is great! No complaint there.Need to get over the no view finder on the camera. Same with Sony ZV-E10. If you are more used to smart phone photo, no issues what so ever.One thing to remember, (for photo) there is no "focus is locked" beep sound when not using AF-S. Only AF-S mode will give you the green focus confirmation and beep sound.Vs. Sony ZV-e10:I really wanted to hold on to Z30, as there are definitely additional benefits/ease using the camera and picture quality is excellent. However, ultimately decided to return Z30 due to focus issue on video. For a camera that is being sold and designed more for video, I found focus issue very odd. It was better photo camera than being the video camera.Pro vs. Sony ZV-E10:No cropping on 4K.Video stabilization is same as Sony, they both suck and will require work post production. However, no cropping on 4k helps with having less crop necessary at post production.Ergonomic is much better. Beefy grip.2 dials to control aperture and shutter speed + ISO button is by the shutter. Don't have to go through menu to pick it. Sony has 2 dials too but not as easy to use. More clicks are needed.Better picture quality. I found picture quality much better in Nikon.Some weather sealing vs none in Sony.2x FN button that you can assign desired setting.Nikon lens adapter allows you to use F mount lenses. Huge plus. Autofocus works well when shooting photo. Your option for lens really opens up because of this. Only caveat is that new FTZ I and 2 adaptor add length and size to your set up. FTZ 2 adapter doesn't give the hump on the bottom vs FTZ 1, but it's like $270...look for a used one. Used FTZ 1 adapter can be found for around $170.ISO/noise is definitely less in Nikon Z30 for both photo and video. How the Nikon takes care of the noise with higher ISO is amazing. In dark environment, even at F1.4 or 1.8, you do have to use higher ISO. I definitely find Nikon Z30 image to be cleaner than Sony.Con vs. Sony ZV-E10:People/face tracking is not always solid.Shutter sound is somewhat "sad" or not pleasing.No HDR recording.Lens options are limited and more expensive due to less 3rd party making lenses for Nikon Z line.Body+kit lens combo is slightly cheaper than Sony, but prime lenses will definitely cost more.No zoom control on dial for zoom lenses.Everything for Z30 was working great except when I realized many videos were not autofocusing on the person (in human eye/face tracking mode). Results were same for prime and zoom lenses, whether they were Nikon F lenses on the adapter or Nikon Z mount lenses. When camera or the person is not moving much, it's fine. When person is moving or camera is moving (slowly) around the person, face and eye detection does happen, but focus is not on the person. It's very odd.Once the focused person is outside of the frame and then back, eye/face tracking sometimes does not work and when it does, focus is not on the person. Focus is stuck on the background. As a result, I don't know if person is actually in focus. I tried it with 4 different lenses and same result. Very frustrating. I have to constantly focus point on the screen, which beats the purpose of the autofocus and also cause shakes on the video. Only solution was having the high F number to keep everything in the frame in focus. However, when subject moves slightly toward the camera, focus is gone on the subject, despite face/eye being tracked. Z30 has around 200+ focus point vs. ZV-E10 with 400+ points. Perhaps that is the issue? It's worse in "darker" environment with eye/face tracking and focus. Red light keeps blinking, telling you that the focus is not happening.If you are using the F lenses with adapter and hear the noise from lens trying to auto-focus, there is no way around this. You need to buy the Z adapter lens...no issue with noise. It's dead quite.I played with several different auto-focus options, sensitivity, speed, and block recovery....all lead to same problem. I really like this camera for photo, but can't trust that videos. Sorry, will have to go back.
