Memory benchmarks, for use on 5DMK2, video only.

posted in: Photography | 0

I will only be brief. The SanDisk cards have impressed me more than any other card in this lineup. The Lexar card doesn’t have enough buffer so when I stop my recording it actually freezes for a moment(4-5secs) then again for a second or two and done. Patriot memory skips a beat on the red led blink and quickly realigns with the seconds counting away, also I get a buffer(occasionally) display for a second then its gone. Remember on the mk2, every second, the red led(the one next to the SET button) status light blinks. Even on the 2GB SD Ultra II the response time was quite amazing, the rest of the memory have slight buffer issues.

On most of the projects, I find myself reaching for the Patriot 16GB(x2) because of the space. I don’t need to change memory cards as often, they are reliable for both photos(RAW) and video(24/30fps-1080p). The Lexar failed 951media on a wedding shoot, luckily He was able to use the recovery software to restore hundreds of pictures of a wedding ceremony and post. Yikes! Remember, FORMAT your memory cards on the camera before using them.
