[@geraldundone]

UPDATE - DEC 18/18 - Sony has released new firmware (v2.10) for the a7 III & a7R III that "Solves the problem caused by a specific third-party memory card, which would not be recognised by Sony cameras." I know that some of you had problems with the SanDisk cards in your Sony, so hopefully this update will fix it. Please post your results if it does/doesn't. 🤞

[@tobostus]

So.. I tested it with my a7 III and now, the SanDisk card also works in slot 1. ;-)

[@SimonZonza]

Update made, the card is functional in slot 1. Thank you.

[@laimonasvitkus2279]

my still not working

[@HowlingWolves77]

Any chance you've heard of the Lexar cards being a problem? I've seen a few complains online about people having issues with them in their Gh5 cameras.

[@foxhouse_tips]

When I bought this card (128GB), the update 2.0 was already installed and it did not work. At this moment, sandisk works well. 32GB always worked

[@iComplainer]

Dude. This video's going to make you a lot of bread in the long run. Make un update for it next year. This is the best SD card guide on KZbin to date.

[@geraldundone]

Thanks a lot for this. I'm glad it's helpful. Thanks for the kind words, mate. Cheers! 😃

[@owlon225]

sadly it isn´t as popular as it should be...but it´s the title, it´s to long and there are many non-important words. Instead of: "The BEST SD Card for VIDEO", he should´ve used something like: "BEST VIDEO SD CARD"

[@ItsFritzDaCat]

Actually was looking at my XQD card and was like wtf is this here mean... on to KZbin and get Undone! ..but ya, need an update with some info for us *whisper* 'Nikon guys' , shhhh... Please Gerald... do it for us Canucks! ;)

[@7alken]

yeah, exactly, the extended contacts SDXC II never seen before; I thought that I know everything about SD, but not here... probably(sure) not usefull for video but yet another difference is random access IOPS for small files writing/deleting mostly ... 10 years ago, some cards used even SLC flash chips and Kingston Ultimate was the beast...

[@MikkelGrumBovin]

youre about as clever as a sofa ,-

[@JohnnyBoyUploads]

Your content is sufficient and perfect! There are a 100 videos out there telling which card they recommend(which might also be sponsored). Your video here just tells how to interpret any card and take a decision ourselves! All your other content tries to do the same and I totally vouch for such stuff! Your channel is my favorite amongst all! Thanks for taking the effort.

[@jackbennett8966]

Where has this man been all my life, his videos are insanely helpful and super info packed. Thank you so much for the content!!!

[@kschumi]

This is hands down the best video about SD cards on YT! Great job and thank you very much!

[@Joel4JC]

Wow! I'm a techy and love the technical side of your videos, keep the numbers and specs coming. Great job!

[@Rubiksguy]

Thank you for actually explaining this in a way I could understand. Best I’ve found so far.

[@sharp_focus]

Finally, one to explain clear and nicely! 👍 Thank you!

[@relaxedcurious]

I regularly return here whenever I'm about to buy a new sd card. Thanks for the great content!

[@prasadpatil92]

One 12 min video that answers all the questions on my mind. Superb! 👍🏻

[@raymurphy7847]

[@geraldundone]

Glad to hear it. Thanks for saying so.

[@AllThingsFilm1]

I forgot to thank you last year when I first watched this. It popped up today. Since then, I bought a few 64GB SanDisk ExtremePro SDXC II, 300mb/s cards, like the ones you showed here. Great cards.

[@brettbaker9027]

Definitely the best SD card explainer I've seen so far. Thank you!

[@geraldundone]

Thanks, Brett! Appreciate that. Cheers!

[@changleon7441]

This is the clearest SD card breakdown video I’ve ever seen. Your talent really deserves a lot more subscribers.

[@geraldundone]

Thanks so much! Really appreciate that.

[@Wada-er4rd]

Hi, thank you for such a quality guide, I watched several videos before your’s , non of them were clear for me. You are the best by far. I’ve bought sdxc 64Gb card and after watching your video know exactly what I got. Keep it up great content 👍

[@mecpratt]

I really never understood my sd cards for the past decade, but I wanted to learn and upgrade mine. Plus, I have a second slot now too. Thank you!! This was super helpful.

[@InsideOut204]

One of the most useful vids I've seen in a long time. Very nicely done!

[@geraldundone]

Thank you very much. Appreciate this. 🙏👍

[@cancerrisj7933]

[@Wellgraf]

Amazing structure and presentation of this topic and video Gerald - Great job and thanks!

[@enframeeternity6681]

Dang. Straight to the point and very informative!

[@piravinpremaruban7431]

Mega. Exactly the video i was searching for !

[@JUSTINBUISSON]

Thank you so much! This was just everything we needed.

[@PKedByBlade]

Video still holds true extremely well, AMAZING video!

[@geraldundone]

Here's the card I was holding in the video - SanDisk Extreme Pro 64GB SDXC V30: geni.us/PwlC Also, one thing I didn't mention in the video is the "x" ratings you see on some brands of cards. (e.g. Lexar 133x). This number is just like the 95MB/s you see on the face of cards--it's the read speed of the card when taking the files off and putting them on your computer. It was based on old CD-ROM read speeds, which had a base of 0.15 MB/s. You just multiply the number of x's by 0.15. So a card with a 166x speed rating would be 166 x 0.15 MB/s = 24.9 MB/s. Alright, now I'm really done. 😜

[@geraldundone]

@Vadim - Sure! 😃 I would recommend the Sony a6500 (geni.us/l53ssL9 ). It can do everything you want and includes 4K. If it's a bit out of your budget, you can consider some DSLRs from Canon, some of the Rebels aren't too big, but they are bigger than mirrorless sytems. The Rebel SL2 (geni.us/9aTvbFq ) or T7i (geni.us/RVZJ5su ) are strong, but don't have stabilization in the body and only do 1080p. Same goes for the less-expensive Sony systems like the a6000 (geni.us/SON6cmx ) & a6300 (geni.us/9oU61zc ). They have everything you want except stabilization. For phones, the best cameras right now are in the Pixel 2 and the iPhone X. They are good, but not as good as the dedicated cameras mentioned above.

[@geraldundone]

No problem! 😃 As far as point and shoots go the G7 is pretty good. But keep in mind that there are no upgrade paths with cameras like that. You can't get lenses, build out your kit, etc. Basically it's a single use item and when you're done with it or you out grow it, you have to start all over again. I think they are good for side cameras or travel cameras, but I don't like them if you are trying to get a serious start on photo/video. Here check out this video I made last month. It might help you: kzbin.info/www/bejne/rmnGf6x-o5etbKs

[@GregMcCall]

Perhaps you should have added to check the specifications of the camera as you might be spending unnecessary extra money getting a faster card if the camera could not handle it (eg. not handle UHS II and falling back to UHS I ) - Unless you have multiple uses for the card and one of the devices could use it.

[@geraldundone]

UPDATE - DEC 18/18 - Sony has released new firmware (v2.10) for the a7 III & a7R III that "Solves the problem caused by a specific third-party memory card, which would not be recognised by Sony cameras." I know that some of you had problems with the SanDisk cards in your Sony, so hopefully this update will fix it. Please post your results if it does/doesn't. 🤞

[@geraldundone]

Awesome! I'm glad. Thanks. 😃👍

[@rm9308]

@@geraldundone The only question is why don't photographers use the microSD version? They're cheaper and when you upgrade you can stick your old card in a phone or a Switch or whatever.

[@mikejonce1]

What a GREAT video! Thank you so much man! VERY informative and helpful.

Thanks, John! Really appreciate that. I think it would be a good idea to update it from time to time as well. Cheers! 😃👍

[@agreennet5213]

You helped out so much with video. I had been searching to find the right SD card for my new fujifilm xp 4k camera. I am not a professional but I did want to find the best SD for the best possible pics and videos with this little camera and tour video did it for me! Thanks!!

[@MrSmildiger]

Nicely clear explained, Thank you somuch

[@JonneytheKidd]

ABSOLUTELY THE BEST INTRO EVERRR!!

[@Photographicelements]

This video is very concise and easy to understand, and again, now I can just forward this video instead of trying to explain things; usu ppl just listen to 1 or 2 points, then TLDR (R=Listen in this case). SD cards have so many critical details that are important to get right, it pays to be meticulous; looking at you neewbies. I've always decided on the price point I wanted to pay for cards, 30-35.00, and waited for the price to drop to get the good cards, (yes, exceptions, but mostly true). I reuse older cards, with low bit rate recording, for audio equipment because audio doesn't ever change, 16bit is top quality, and no one records in 24bit; there won't ever be a 4k audio, just additional tracks; also most audio recorders max out at 32Gb. Nothing on Hoodman or Sony Tough cards? The card you recommended is top quality & reliable; also I own these cards. As a side note, I've included older cards with the sale of older cameras to set them free.

[@KrishnenduKes]

Just this video alone made me subscribe to your channel. Great knowledge sharing. Thank you.

[@PeterMoriarty_]

THANK YOU, super helpful and i learned heaps

[@FrederickDunn]

Very Helpful, thank you so much! I often need refreshers on SD cards etc. All I need to do is be capable of recording 4K at 60 fps. Since the higher speed-rated cards are double the price, I'm going to be ok with a SD that is rated C10, 128 GB Capacity, SDXC V30 I, I don't care about the download speeds once back at the editing station, so at 170 MBs, I'm fine with that. Thank you, all great information well presented.

[@noxlupi1]
