Sony Z90 vs AX700 4K

Right techy question, trying to work out the differences between:

4K on X70 / Z90 and 4K on AX700

I know that the X70 / Z90 is XAVCL (MXF) at 4:2:0 8 bit and the AX700 is XAVCS (MP4) at 4:2:0 8bit
Is that the only difference - the wrapper, or is their more to it?

No change with 4k. Still 8 bit 420.
The Z90 will have an S-Log option. You may want to check if the AX700 will as well.

I would buy 2 AX700's for 4K work for the same price as one Z90

Re: Sony Z90 vs AX700 4K

Between the AX700 / NX80 / Z90 and the X70.....

The X70 uses the first generation Son 1 inch-type sensor. This is the same sensor in the AX100 and original RX10.

The AX700 / NX80 / Z90 us the latest generation of this 1 inch-type sensor. It's and "RS" backlit (BSI) with on-board RAM. This sensor is pretty damn bad-ass for it's size. It's now in the RX10-III/IV and Z150.

In my opinion, this newer sensor is significantly better than the older model and cleaner using high gain.

Also, the AX700 / NX80 / Z90 have picture profiles that support more allot dynamic range then the X70 including 4 HLG modes, rec709 800% and both Slogs. (although SLog-3 is unusable)

If you only need 4k and dont shoot 1080, then get the NX80. If you need 1080 (10bit) and want SDI then get the Z90. (I stopped shooting 1080 altogether about 2 years ago...so I got the NX80)
