Using micro SD cards with adapter

[Jamsoury]

I have some good micro sd cards, is there anything negative about using these micro sd cards with the SD adapter in my a7rii? It won't be my primary use for a memory card but if there's nothing wrong with using it, it'll work as a backup.

Ill be recording 4k videos on it. The cards can do 90MB/s

SD card adapters can fail. Whenever possible, use regular SD cards (or whatever the camera normally takes; try to avoid adapters). If you leave the microSD card in the adapter and don't remove it, you can lessen the likelihood the adapter can fail, but in general (IMO) use of memory card adapters should be avoided when possible.

Others will give their thoughts, but this is based on my experience, even using brand name cards like Samsung and Sandisk. Every once in a while you get an adapter that just fails for no reason. Card is still good, but not useful because you don't have an adapter.

Secondly, best to always carry spare cards with you. At least one extra, two or more if you have them. In case you fill them up or one fails.

Personally I don't like another interface between the camera and the storage device. Besides, SD cards are cheap and for little money you can get faster cards. I can find a Sandisk 32GB, 95MB/s card for $22, or a pair of Lexar Pro 64GB, 150Mb/s cards for $58.

I've been using a micro sd card with an adapter in my Canon 6D for a year or two without any issues so far. I quick format (in camera) the card after I've downloaded (and backed up) the previous shoot. And I always carry a spare card.......just in case.

The OP wants to shoot 4k video with their card...that generates a lot of heat constantly writing to the card. It's not like photography where it writes in a short burst after each image is taken.

There is nothing really wrong with this opinion

So far I have had one micro fail but not the adapter.

Secondly, best to always carry spare cards with you. At least one extra, two or more if you have them. In case you fill them up or one fails.

Very good consideration. I try to carry an extra card. One cool consideration for adapters is that my phones take micro SD cards. In a pinch I can pull out that micro SD card and use it in my camera. I have only had to do this once but it is a consideration. You can also use Micro sd cards in action cams and other devices. You cannot put a full size card in an adapter and use it in a micro device.

Then again the price on cards has become so low it shouldnt be a large burden to buy decent cards and have spares.

Obviously storage is important because cards are easily lost. Also CAN be damaged.....

I my limited experience with micro-SD cards, they are less durable, easier to lose, and more likely to fail. I only use them in devices that require them, and swap them in and out as seldom as possible.

No, I haven't shot any video with it yet. Just curious............does the outside shell of the adapter get hotter than a regular sd card when shooting video? I have noticed that my Lexar micro sd (usb 3.0) card reader gets very hot when It's hooked up to my computer, but that may be a different scenario as far as heat build up and dissipation is concerned. My response to the OP was that of my experience with the reliability of using a micro sd card and adapter. Thanks for pointing out a problem that might occur when taking video. I'm looking forward to other responses to this, as I may someday take video with my camera. I would certainly use a regular sd card if a micro sd card and adapter causes a heat issue.

I guess in the end, IMO if you leave the card in the adapter (And try not to remove an re-insert it into the adapter more than necessary, as i think this will out the pins in the adapter over time thus leading to adapter failure), and you carry spares (cards and adapters) you should be fine.

I personally don't have use for microSD cards (the only thing that uses them is my tablet, which the card just stays in there all the time and is never removed). Other than that, I've just mainly used SD cards for cameras (as all of mine take regular SD cards). I've had a few microSD cards & adapters in the past and have had a mixed experience with them.

But like I said, I think if you carry spares, you'll be fine.
