Does anyone know what the largest SD card size is supported by the Z190?

I'm pretty sure there is no size limit. Sony doesn't mention any limit in the operation manual.

Be warned that there is a limit of 600 clips on a card, regardless of their length. So, a really large 512GB card might not be appropriate for b-roll, etc. where the shots are relatively short. For interviews, meetings, performances, etc. longer cards can work, but how many eggs do you want to put in a basket? You better be using high-quality genuine cards from name-brand companies and reputable resellers.

I went with the SanDisk 128GB Extreme PRO UHS-I SDXC Memory Card. They are low enough in cost to buy several and I plan to carry a USB hard drive so space shouldn't be a problem.

Thanks for the Information.

I'm looking forward to your "Doug Jensen's Sony PXW-Z280 and PXW-Z190 Master Class" after I make my purchase.

You won't be dissapointed, I streamed it twice :)
