New Cameras - will I buy them?

As I mentioned previously, I am planning on ditching the A-mount as new technology emerges, leaving my A99ii in the dust. For example, I really enjoyed using the A9ii's video AF to track a dancer walking up the stairs towards the camera. It wasn't perfect, but definitely a thousand times better than what the A99ii could do with its locked aperture at 3.5.

To be honest, the perfect camera for me right now is the 45MP Canon R5. A bit expensive, but it has everything I would want from an A99iii if Sony ever made one. Not too many megapixels, but enough to crop if needed. Sony came out with a 63MP camera, the A7rIV, but that one would just waste disk space for me. 

That means that Sony doesn't currently make a camera that is perfect for my needs. I actually don't mind the overheating of the Canon R5 as the A99ii also overheats and I learned to live with it. I don't do a lot of long form videos and will just shoot 1080p 24p if I need to, a format that would work fine for most of my clients.
So why wouldn't I but a camera that is somewhat expensive but perfect for my needs? Unfortunately there is no converter/adapter from A-mount to the Canon RF mount, so I would have to but all new lenses, accessories and cards which would prove too expensive. Even just switching from A-mount to E-mount I might have to buy two adapters totaling around $500.

The good news is that I upgraded my editing workstation, so it's ready now for bigger photos in case I do decide to get the A7rIV. All my internal drives are now SSDs and I have more RAM too so I'm ready for non-choppy 4K editing.

I really like the improvements in the A7sIII that just came out. They changed the menu system! That's really great as even after four years with the A99ii I still struggle with its outdated menu system. That said, as I am transitioning into more video work, I still mostly need a solid hybrid video/stills camera with the ability to crop. Some of my clients still need to print a large A3 (or equivalent) size album for which even a 24MP camera might not be that great if you need to do any cropping.
As wedding season is practically non existing right now due to COVID-19, even with more money coming from my current documentary editing gig, I will hold off buying a new camera. All I want is for Sony to create a better camera that is exactly like the one I have but with much improved AF, video and menu system. If they don't, I will probably settle for the A7rIV at some point.

My Setup for Sound

In the good old days, I had a professional video camera with XLRs built in and a great preamp built in. If that wasn't enough I would hook it up to a portable XLR Mixer that the sound person would strap on themselves along with a boom mic.
Now, ten years later, technology has advanced and I no longer put a lot of equipment into a beat up student car or a nice looking van borrowed from my parents. Instead, I bike around, with all of my equipment inside my supercharge touring bicycle.
I'm also using a hybrid stills/video camera (still the A99ii) to shoot everything, at least until I can afford to switch to e-mount. The good news is that the A99ii has a terrific built-in microphone that is great in a pinch. Even if you're not planning on that microphone it provides better sound to allow Adobe Premiere Pro to sync the sound from the internal microphone with that of a better sound recorded from an external recorder.
Most of what I do when recording sound on my current video gigs is interviews with people sitting or standing.
The bad news is that the pre-amp on the A99ii is TERRIBLE.  For a while I was recording to an external Zoom recorder I've had for 7 years and got good results, but had deal with syncing audio in post, and not forgetting to press record on both the camera and the Zoom.
I was using a no brand lav mic for a few years, and had to deal with lots of PL 3.5 cables. It was also a problem when recording an interview with a person who needs to go to the bathroom.
I got the Rode Go Wireless Compact system after getting strange noises on the Sony ECM-W1M system and mediocre sound. The Rode Go is really small and easy to pack, seem to be one of those rare times where audio/video manufacturers remember that it is 2020 now and match the technology to that of smartphones. I got the Rode Smartlav+ microphone to go with it which is a solid lav mic but requires to also get the Rode SC3 3.5mm TRRS to TRS Adapter for smartLav because it was originally meant to connect to smartphones.
Finally, I go the SR-AX100 audio mixer that sits on my camera, underneath the Rode Go's transmitter. Sure, it's a kind of a weird tower now, but now I can connect all this straight to the camera and not worry about an external recorder running out of battery or memory card. The SR-AX100 is one of those rare electrical machines that does NOT need a battery to operate. It will also allow me to connect another microphone and record stereo to two channels in case I ever do an interview with two people or still want to record some sound where the camera is along with sound coming from the lav mic.
If you like your mixer under your camera you might get the SR-AX101 which is basically the same product but hooks under your camera, a setup I don't like and will avoid.
