I can’t stress enough the importance of using the correct cards for the job. Only tonight I had a timely reminder the difference between true class 6 and class 5.5 ! I was filming a local Cub and Scout group using a Sony EX-3 and decided to use 2 8GB cards…One Transend Class 6 and the other a Panasonic Class 6.
Filming in 1920 x 1080 I had 28 mins per card the 1st being the Transend. Seven thirty PM the Scouts barge in and I am swapping slots, the second card (Panasonic) kicks in and all seemed well till I got a “restore media warning” I decided to switch off the camcorder and when it came back on I was asked to “restore media” with a choice to cancel or execute, so I decided to execute.
Everything seemed well till this happened again, I went through the same process and took a decision to swap out the MxM card holder with the Panasonic SDHC card for an 8GB SxS card, I only had this card and a 16Gig Transend which I was saving for another job.
I have tried a 16GB Verbatum Class 6 and an 8GB Panasonic class 6 in the MxM card holder, both gave me trouble in fact the Verbatum was a non starter.
The moral of the story is if you are using the Sony EX-1 or 3 and you intend to use the MxM card holders you must stick to a brand that you know is truly class 6 like the Transend SDHC card. Transend also produce a specific video SDHC Class 6 card which I have also tested and works fine. Do not be confused by the times given on front of the card this is for domestic customers.
