Another Exciting Discovery with my DVX200

[MScrip]

All I'm saying is that the dvx200 is limited to UHSI and cannot take advantage of the speed advantages of UHSII cards. It can use the cards but will revert to UHSI and it's anyone's guess what speed it will arrive at without using the additional contacts on the card.

UHS-II cards are designed to be backwards compatible with UHS-I devices. It's built into the spec.

I just realized that all my main cards are UHS-II... in particular Lexar 64GB U3 UHS-II cards. Yet I don't have a camera that can take advantage of UHS-II. My current cameras are a 2013 Canon 70D and a 2011 JVC HM-150 camcorder. But they work perfectly fine using the UHS-II cards.

I have also used these cards in a FZ1000 even though it only accepts UHS-I.

So I'm just having a hard time believing that you shouldn't use cards that are "better" than what the camera is rated for. Usually things like that don't affect anything.

Or to put it another way... I've never seen any documentation that says NOT to use UHS-II cards in a certain camera.

Still: there's no gain in buying UHSII if the camera is UHSI

There might not be a gain in the camera... but you'll notice a gain in speed when you're offloading the footage to the computer!

Well sadly I have had problems with a Lexar UHSII cards rated at 150mb/s and U3 rating in a BM video assist that drops frames with these cards and also in the DVX200 which stopped recording and threw up an error message with these cards. There is just no telling at which speed rating this card will perform in the camera since it's rated for UHSII performance. For the DVX200 it is very critical to have the right card and I've never seen any problems with the Sandisk extreme pro UHSI U3 95mb/s cards. The cameras you are referring to never reach the data rates of the DVX200.

My DVX started to flicker a few times as if losing power, but stayed on. Some of the content was blurred as if the auto focus stopped working. This happened twice. Thought it was my imagination because it happened so fast and recovered immediately - but it happened. There is obviously something going on and Panasonic should be made aware and address it.

I also exclusively use the Sandisk Extreme Pro U3 cards (64Gb, 128GB, and 256Gb). No problems yet!

It is good to here that 256GB cards work ok. I have stuck with the 128GB cards for now but will try the 256GB cards on longer shoots. I also just use the Sandisk UHSI U3 cards only. I have never had a problem with them in other gear I have as well.
