John, for fast past moving subjects, I would guess that 50Mbps of pure 4:2:0 8 bit goodness would allow less compression artifacts over the 10 bit 4:2:2 50Mbps Z90...not sure about high speed framerates though.

Mark, for my HLG testing, tried 4K as well as HD 10 bit 4:2:2. I have an S8 phone, so maybe I will throw a file at it for kicks. When I set FCPX to export out the HLG file in REC709, they look " similar" to the REC709 recordings, just a lot more shadow noise...more noise in general, less contrast...using the FCPX presets at least.

Sure wish I could remember where I read about the difference, though. The other concern is about highlights and darks, especially in August, although with global warming now we're seeing fewer grey skies.

Edit: Paul - glad to see you started a new thread "Working with HLG footage" so, hopefully, the FCPX workflow is all sorted out if and when I get there.

Bruce - It was let go for $850 on Craigs List in the afternoon and shortly after had a buyer at the listed price and picked it up the next morning. There was one other AX100 listed for $1,050 so that may have helped. Will continue to use the AX53 a B-cam.
Edit: Currently the AX53 has got a temporary promotion to A-cam status.

Re: Introduction to the Z90, NX80, and AX700

After three months of being without an A-cam has been very difficult. Three months of going back and forth about the next cam to get, weighing options, tradeoffs, costs, needs, wants, … and finally couldn’t take it any longer. Had to get something!

The new cam in the quiver, replacing the AX100, is now the AX700. It has a lot of various useful, albeit in some cases minor, upgrades over the AX100. The cumulative effect is there are more control options via a larger menu. One nice item in the box was the Large Eyecup. Never realized how nice this would be but when outdoors in the sunlight this item is absolutely super.

The viewfinder and LCD screens are really sharp. Compared to the AX100 this cam has a lot more heft so won’t be as much of a “handicam”. Audio inputs with XLR cables will be via the JuicedLink pre.

Battery: the NP-FV70A is rated at 1900 mAh vs 1960mAh of the NP-FV70 that is standard with the AX100. What is weird is, even though the 70A has fewer mAh, it is about 6mm taller. Go figure. Wonder what they have inside.

Haven’t had time to really shoot anything with it yet, well, maybe except for maybe a couple minutes worth after getting the battery charged up. Looking forward to doing a shoot with the AX53 as the B-roll cam.

Anton Bauer batteries have been growing in size but with no gain in wattage. The explanation from them is the larger cases allow better heat dissipation during charges, keeping the cells healthier and allowing longer battery life. But maybe Sony just sourced new slightly different cells from Sanyo or something...more likely

Spacing them out just a little bit makes a lot of sense because the cases do get warm with usage, particularly some usage, even charging, so the heat must have a negative effect on the chemistry and dielectric, and therefor battery life.

The width of the typical battery case is fixed by the cam but the height typically is not so they can "grow" that direction. I was kinda wondering if there was some new circuit board inside to help process battery information but I don't have any old one to take apart to find out. Of course, one would need a NP-FV70 and a 70A version to compare.

As for telling counterfeit apart from the OEM ones, Sony Support told me that only the Sony Repair Center can tell them apart via the green holographic insert on the end of the battery. There is also a manufacturing date written in the lower right corner on the back.
