I pull my cards often to edit this is strong enough to stand up to the riggers of removing and replacing cards in computer and camera.

Expensive but better constructed.

I had one of the card which should be replaced by Sony as a card which can be defected. I applied for replacement and Sony didn't contact me back for weeks. Today I had a Card Error and I lost all photos and videos. Never again Sony. I back to SanDisc.

Card Error !!! Lost all photos and videos !!!

Fast, fast, fast

Great set of SD memory cards! I've had no problems with the M series.

Great SD Cards

I own a Sony A7m3 and this is a recomended card for Photo and Video. So far works very good, I haven't had any issues and it's super fast.

So far it's working as expected

I mainly use Sony SDXC cards while operating cameras at work--at home I still use various SDHC brands. When I upgraded to a GH5 however, I knew I'd had to purchase faster cards to match the much faster 4K bit-rates. The Sony M series does not disappoint. Lighting fast, even at my cameras highest settings (4K All-I 400mbit)! Excellent build quality, too--and not quite as heavy a hit on the wallet as the Sony Tough series cards are, which I'm not sure are worth the price unless you'll be using them in the rugged conditions they're designed for. Can't go wrong with these cards is all I can say.

Best SDXC Cards I've Used (Especially with the GH5)

I have been using the Sony 64GB SF-M UHS-II U3 for awhile now for all of my still Photography and so far they have reliable. I would recommend this SD card

Good product

So far just in the fews weeks I've owned the cards they have worked well. Can't go wrong with a Sony card durable for years.

Perfect mix of performance and price

Card has worked well and is fast on a USB 3.0 reader. Makes it faster to transfer photos to the computer. I have not noticed any differences in camera operation.

Good price for a fast card

I love this card. I have a Sony A7III and use it on hi-burst mode for concert photography. With previous cards like the SD-UHC I SanDisk Extreme, I had to sometimes wait for the camera to write to the card in order to continue shooting - when the moment is everything, that's the opposite of ideal. With this mem. card, I can take continuous bursts and never have to stop to wait for the card to write. The 128GB size also gives me the freedom to not worry about switching out my card to capture more - between my 128 and the other slot which has a 64gb (and a camera setup that writes on to the other card one is full) I have yet to hit my storage cap. 

It also reads at least 20% faster than my other cards, meaning I don't have to wait as long to get everything in to Lightroom.

Fast as lightning, no more waiting to take photos

No problems with cards in both my Sony cameras.

No problems.

No problem with card in both my Sony cameras.

No problems

Bought this for my Sony A7RM3 and it works a treat. Although I do not do video, I find it is ideal for stills shooting.

Fast card and great value.

Have these in the Fuji X-H1 and have never had an issue.  Will hold 1-2 hours of HD video or ~1k compressed RAW photos no problem.

Work great for the Fuji X-H1

As far as handling 4K ProRes HQ footage on a Blackmagic 4K Video Assist recorder, it seems to be doing the job, no dropped frames. It indicates that it reaches its advertised write speed of 100 MB/s. However, in a tested Lexar LRW400U Rev A  UHS-II reader it shows write speed of 61.9 MB/s and read speed 90.1 MB/s. The same reader shows 150+ MB/s write speed on a Lexar 2000x UHS-II card. It's a possibility that somehow the reader cannot take full advantage of this card UHS-II interface, but aren't all UHS-II cards supposed to comply with the same standard?

It works, but...

Professional SDXC card that works very well with my Sony PXW-Z90V professional camcorder.

Highly Recommended SDXC for Professional Camcorders

It works perfectly with sony a7iii , i definitly change my opinion about the SD card un-brand

The Best SD CARD of 2018

Operates well when used with the Sony A7R III.  Before purchasing the Sony 64GB SF-M Series UHS-II U3 Class 10 SDXC Memory Card, Maximum 260 MB/s Read - 2 Pack, I used older SanDisk memory cards.  Unlike the older cards, this card does not lag behind per my shooting style.  At the time, I purchased an extra one as a back up.  I would recommend this card to a friend.

Works well with the A7R III

Have these in my Fujifilm X-H1 and haven't had any issues for holdups due to the speed.  Download speed onto my computer seems pretty quick as well.  Nice cheaper option for UHS-II.

Work Great for anything the Fuji X-H1 can do.

very fast card... so far so good... works fine...

one of the best...

Cards have an excellent write speed, work well with 4K video.

Would recommend for medium grade 4K cameras.

I love this card, they are fast... I don’t have any issue using with my gh5

Perfecto

Perfect match for my Panasonic GH5 4K camera. No problems whatsoever in recording my footage, which allows me to focus on my scenes and subjects.

Perfect match for DSLR video

I am using these on my A7III and am very happy so far. Write speeds are great and I havent experienced lags. I will probably buy more for backup soon

Great speed

Like most of their products, these memory cards are robust and fast. I've also found that Sony offers some of the best web support features available, so I never hesitate to buy the brand.

You won't regret the purchase!

Records video for 30 continuous minutes on A73 at 4K 100mbs without issues.

4k 100mbs no issues

High quality as you would expect from Sony. Used with Sony camera and have no problem shooting at best speed.

high quality as you expect from well known brand

Excellent

Great speedy cards.  Upped my game and not looking back.  Reliable and fast with my A7III.  Though would consider the next level up in the future.Got a great price before BF '18.
