SonyM series SDXC UHS-II Card 256GB, V60, CL10, U3, Max R277MB/S, W150MB/S (SF-M256/T2)

Bought two - Love these cards! I use them with Sony A7IV and shoot weddings, events, portraits, and some sports. I always shoot RAW Uncompressed files. I've always used Sandisk Extreme Pro 128g / 200mbs cards with my Sony A7Rii and always had issues with the buffering wait time (granted it is a 42mp camera and has huge file sizes). Although the Sandisk card says 200mbs, the write speed is only around 90mbs. I tried the Sandisk 128g/ 200mbs (90mbs write speed) in the A7IV and it did really well, BUT these Sony M Series cards with 150mbs write speed are perfect. I didn't run into any problems at all with buffering like I did with the Sandisk 128gb / 200mbs cards.These M Series Sony cards with the 150mbs write speed are the ticket for sure. Even shooting back to back burst images (about 20 images) the buffer was only about a second and I could immediately shoot another burst. I use this technique often to later create GIFs of the moment. There were times I would miss a shot during ceremonies or receptions because I would be waiting on the buffer, but not any more. I could see possibly having some limitation if you are trying to take more than 20 or so photos in burst for a longer period of time. Or if you are shooting on the newer A7RIV, maybe those 62mp file sizes may overload the buffer a bit more. But all in all, I am extremely impressed with these cards and how well they've handled the files so far.Ultimately, these are fantastic cards and perfect for my A7IV and how I shoot. I plan to get many more of these cards for this wedding season. Highly Recommend!

I recently bought a Sony M Series SDXC UHS-II Card 128GB to use for my public affairs photography and I am extremely impressed with the performance. The card works like a dream in my Sony A7 IV and is incredibly fast. It easily handles large files and transfers are quick and effortless. I am quite pleased with the storage capacity of 128GB, which enables me to store more photos than ever before. The card also offers great protection against data loss due to its advanced error-correction technology. All in all, I would highly recommend this card for anyone looking for reliable storage solution for their Sony A7 IV camera.

Purchased a couple of these in January 2019. 50 weddings and over 150+ photography shoots later these are still working flawlessly.Went from back up cards on my D850 to Z6 to Z6ii’s.Now I’m shopping for CF express cards for the Z9 I’m ready to go to and again I’ll be choosing the Sony brand for storage.Why skimp on memory cards? 2K+ camera and lenses that are $2,500 and up. The ONLY part that retains all that $ is your SD (or type you use) card.It’s the equivalent of tires for your car or truck.The only part that touches the road yet people want cheap. Don’t go cheap, these are a great value and I’ve not had one fail yet.Be sure to always format your cards for EVERY shoot! I’d buy these agin over the other brand.

Works perfectly for me with the a7r3. I don’t know how it compares to the faster one that writes up to 299 mb/s because I haven’t tried it, but I’ve never felt hindered shooting portraits, events and nature, even uncompressed raw. The uhs-1’s were definitely slow by comparison and could not keep up with continuous shooting, even slow fps. If you are an extreme fast-action photographer and need to keep shooting dozens of continuous shots over and over, you’ll probably want to compare the faster cards but for me and I imagine most typical shooters, this is plenty fast enough and roughly half the price.

Works well in gh5 . I shoot 1080 and I've never gotten memory error. Can't speak for super high settings.

UPDATE : having used these cards a quite a few times now, I think they are underwhelming. I bought a new USB3 SD card reader and I'm still not getting any better read /write times. In fact was more unsettling is that they ramp up their write speed and it takes several seconds for them to hit full speed which is still under spec. OTH A sandisk card I have instantly hits its R/W speeds and is faster... and costs 1/2 the price. Thinking I may return these.Working fine to record 4K 400mbit in Fuji XT3. My 2 SD card readers, one attached via TB3, the other via USB3 have write times of 85mb/sec and 70 mb/sec. clearly one SD card reader is a bit slow but the other one but I'd expect better write performance. already filled the cards once and that made no difference in test times, which is good.

I use it on a Sony 4K camcorder and this card is just right for the price , reliability, write speed, and capacity. I use two in the camcorder and set it to make duplicate copies on both cards. I never erase my sd cards, so I am conscious of the price. Also, 4K video eats memory and I won’t use any below 125 GB cards. These fit the bill perfectly.

Purchased 4 of these to run with my new Olympus OMD EM1x.... I'm a hybrid shooter and between video and photography I need cards that will keep up. With this new OMD E1x the buffering is unreal. This camera needed a storage that could keep up and these Sony SDXC UHS-II 128gb cards were a perfect match. I was dreading the higher priced SanDisk Cards running almost $189 each...ouch! And with me needing 2 pairs (4 total) that was more than I wanted to spend. UHS-1 cards weren't going to cut it either so was all too happy to find these.

Using for a while now with no issues. I do long form recording and never experienced overheating, which does happen with some lower end cards.

Predictable great quality cards. Added 2 more to my fleet of 6. They're a bit pricy if not on sale, but worth the dependability and speed.

Great card that works like a dream when transferring big files from a 61 megapixel camera.

Genial, llevo años usandola y jamas me dio un problema

Je savais ce que j'avais besoin pour mon A7iii, cette carte est top même si trop cher je trouve
