Below is a reblog from ARC friend, Eduardo Angel, with the inside scoop on where to find the best SD cards for your money.
I’ve spent a LOT of time trying to figure out what are the best/fastest/cheapest memory cards for my brand new Panasonic GH4.
At first the options seem endless, but they really aren’t. I hope this short article saves you a headache and a few hours of research. Please consider supporting this site by using our links.
Few people know that Panasonic has a brand new SD Card to support the GH4. It is a 32GB with up to 90/45 MB/s, and supports Ultra High Speed Class 3 specification (U3). It is available now at Adorama for $59.95.
I happen to have one, so I’ll be testing it to shoot 4K and will share my impressions.
According to Sandisk, the officially supported cards for the GH4 are these:
Getting an 8GB or even 16GB nowadays, especially if you are planning to shoot 4K video is kinda silly. So here are the direct links to the 32GB and 64GB options:
SanDisk Extreme Pro SDHC UHS-I Memory Card_32GB (Part Number: SDSDXPA-032G-A75) Best price: $49.95
SanDisk Extreme PRO SDHC/SDXC UHS-II Memory Card 32GB(Part Number: SDSDXPB-032GB-A46) Best price: $129.95 at Adorama
SanDisk Extreme Pro SDXC UHS-I Memory Card 64GB (Part Number:SDSDXPA-064G-A75) Best price: $98.95
SanDisk Extreme PRO SDHC/SDXC UHS-II Memory Card 64GB(Part Number: SDSDXPB-064GB-A64) Best price: $244.95 at Adorama
We could also the same Panasonic 64 GB microP2 cards that we used when we tested the GH4 prototype, but at $340 for 64GB I believe I’ll pass. We are also VERY intrigued by the new Transcend 64 GB High Speed 10 UHS-3 Flash Memory Card 95/60 MB/s (TS64GSDU3), but it seems too good to be true: only $50.70!?
I’ve had mixed results with Transcend cards in the past but I wonder if things have changed. Just because I’m feeling a bit courageous, I just ordered one and will be testing it in the next couple of days. Will share my findings on Twitter (@EA_Photo), so follow along!
My brilliant friend Sean Davis had something interesting to say about this:
“Based on the official specs and what I’m being told, only UHS-III cards are tested and approved for 4K capture. I don’t believe the Transcend will work, although some people have had luck with slightly slower/cheaper cards. From my personal and professional experience if slower cards work they will run a higher risk of failure (buffer under run errors and such). The data rates on this camera are incredibly high, 200mb/s in 1080p will usually mean that you need cards capable of that write speed.”
Another option is to go with an external recorder like an Atomos Samurai Blade, or an Odyssey 7 or 7Q. All these come with a critical 1280 x 720 display, and the convenience to record directly from the sensor to 10-bit, 4:2:2 Apple ProRes or Avid DNxHD, but we are talking $1,300 to $2,300.
