Best Memory Card for Panasonic Lumix S5 II
The Panasonic Lumix S5 II is a powerhouse, finally bringing phase-detect autofocus to the L-mount. However, its high-bitrate 6K video and 30fps burst shooting require storage that can keep up without choking. If you use slow cards, you’ll face frozen buffers and dropped frames just as the action peaks. After testing dozens of options, I’ve found that while the SanDisk Extreme Pro UHS-II remains the gold standard for reliability, there are several specialized alternatives that might better suit your specific workflow and budget.

Best Memory Card for Panasonic Lumix S5 II: Detailed Reviews
SanDisk Extreme Pro UHS-II V90 View on Amazon View on B&H
When you’re shooting a paid gig with the S5 II, the last thing you want is a “Card Error” message. The SanDisk Extreme Pro V90 is my top recommendation because it has never failed me across years of Lumix testing. With sustained write speeds that easily handle the S5 II’s 200Mbps 4:2:2 10-bit internal recording, this card ensures your buffer clears rapidly during high-speed photo bursts. While the S5 II doesn’t have the All-Intra 800Mbps bitrates of the “X” model, the V90 rating provides a massive safety margin for the most demanding 6K Open Gate modes. The only real downside is the premium price tag, but for mission-critical work, that investment translates to peace of mind. It’s shockproof, temperature-proof, and waterproof, making it a rugged companion for outdoor adventures.

Kingston Canvas React Plus V90 View on Amazon View on B&H
The Kingston Canvas React Plus is essentially a “cheat code” in the memory card world. It offers genuine V90 performance—meaning it’s guaranteed to maintain at least 90MB/s write speeds—at a price point where many competitors only offer V60. In my testing, I’ve found it to be incredibly snappy when offloading footage, thanks to the included UHS-II reader that often comes in the box. For S5 II owners who want to utilize the dual SD slots for “Backup Recording” without spending a fortune, this is the logical choice. You get high-end performance for 6K video and 30fps RAW bursts without the “SanDisk tax.” The build quality feels slightly more “plastic-y” than the Sony Tough series, but performance-wise, it punches way above its weight class.

Lexar Professional 1667x UHS-II V60 View on Amazon View on B&H
If you primarily shoot 4K 60p or high-resolution stills and don’t plan on pushing the S5 II’s highest bitrate 6K modes every day, the Lexar 1667x is a fantastic entry point into the world of UHS-II. Most users don’t realize that a V60 card like this is actually perfectly sufficient for the S5 II’s internal 200Mbps recording (which equates to 25MB/s). I find this card exceptional for wedding photographers who need large capacities (like 128GB or 256GB) across multiple slots without breaking the bank. It won’t clear the buffer as instantly as a V90 card during a long 30fps burst, but for most shooting scenarios, you won’t notice the difference. It’s a reliable, no-frills workhorse that significantly outclasses any older UHS-I cards you might have lying around.

Sony SF-G Tough Series UHS-II V90 View on Amazon View on B&H
Sony’s Tough cards are built differently—literally. Unlike standard SD cards that are two pieces of plastic glued together, these are a single solid piece. They have no write-protect switch (which often breaks off) and no fragile ribs on the connector side. If you are a travel photographer or documentarian taking your S5 II into humid, dusty, or cold environments, this is the card you want. Beyond its physical armor, it is one of the fastest cards on the market, boasting 299MB/s write speeds. In my experience, it handles the S5 II’s buffer more efficiently than almost anything else. It is undeniably expensive, but you are paying for a card that is virtually indestructible. For those who have ever lost data due to a cracked SD card casing, the price is a small one to pay.

ProGrade Digital SDXC UHS-II V60 Gold View on Amazon View on B&H
ProGrade Digital was founded by former Lexar executives, and their expertise shows in the reliability of their “Gold” V60 series. These cards are specifically optimized for video workflows. What makes ProGrade unique is their “Refresh Pro” software, which allows you to monitor the health of your card and “sanitize” it to restore factory-fresh speeds. For an S5 II user who shoots long-form video (like interviews or events), this card offers incredibly stable sustained write speeds. It doesn’t drop performance as the card fills up, which is a common issue with cheaper generic cards. It sits in that “sweet spot” between budget and professional, offering high-end consistency without the V90 price jump. If you value data integrity above all else, ProGrade is a brand you can trust.

Frequently Asked Questions
Does the Lumix S5 II require V90 cards for 6K video?
Technically, no. The Lumix S5 II records at a maximum internal bitrate of 200Mbps for its 6K and 4K modes. A V60 card, which supports up to 480Mbps, is more than enough to handle this. However, V90 cards are recommended if you want the fastest possible buffer clearing for high-speed still photography or if you are using the S5 IIX variant with higher bitrate All-Intra or SSD recording options.
Can I use my old UHS-I cards in the S5 II?
Yes, you can, but I wouldn’t recommend it for anything other than casual photography. UHS-I cards will bottleneck the camera’s performance. You’ll notice the “busy” light staying on much longer after a burst of photos, and high-resolution video may stop recording unexpectedly if the card can’t keep up with the data stream. Since the S5 II is a high-performance machine, it deserves UHS-II storage.
Are both card slots in the S5 II the same speed?
Yes! One of the best upgrades from the original S5 is that both SD card slots in the S5 II are UHS-II compatible. This allows you to shoot in “Relay,” “Backup,” or “Allocation” mode without the second slot slowing down the first. This is a huge advantage for professional videographers who need an instant backup of their footage on a second card while they shoot.
How much 6K footage fits on a 128GB card?
At the S5 II’s standard 200Mbps bitrate, a 128GB card will hold approximately 80 to 90 minutes of 6K footage. If you are shooting in a lower 4K bitrate, you can get significantly more. For a full day of wedding or event coverage, I usually carry at least two 128GB cards or one 256GB card per camera to ensure I don’t have to swap cards mid-action.
What is the difference between V60 and V90?
The “V” rating stands for Video Speed Class. V60 guarantees a minimum sustained write speed of 60MB/s, while V90 guarantees 90MB/s. Note that these are “MegaBYTES,” not “Megabits.” Since the S5 II records at 200 Megabits per second (25MB/s), both V60 and V90 exceed the camera’s internal requirements, but V90 provides more headroom for the camera’s processor to offload the buffer quickly.
Final Verdict
For the majority of Lumix S5 II users, the SanDisk Extreme Pro V90 is the safest and most reliable investment for high-stakes shooting. However, if you are building a kit on a budget, the Kingston Canvas React Plus offers the same V90 speeds for much less. If you primarily shoot stills and standard 4K, the Lexar 1667x V60 is more than enough. No matter which you choose, ensure you are utilizing the camera’s dual UHS-II slots for the best possible experience.
