The Official Canon 5D Mark III website says:
CF Cards (Type I); Compatible with UDMA CF cards; SD, SDHC, and SDXC Memory Cards
Note: No microSD is supported unless you use a microSD-to-SD adapter.
It's also worthwhile to mention, a MicroSD-to-SD adapter would not bring any loss of performance (either in writing or reading speeds) ...
There is likely a hidden folder on the card somewhere that is using up your space.
Using a utility like DaisyDisk on the Mac will help identify the missing space, and let you clean it up.
I have found that some cards have ".Trashes" folder that gets created and keeps copies of a bunch of junk you've deleted in the past. removing this folder will let you ...
The Canon 500D takes SDHC cards up to 32gb. Any Class 6 or above will make sure that there is never a slow down from the cameras buffer filling up, and the 30MB/s card you mention is a Class 10 card so plenty fast. I just bought two of those myself to replace my 16gb PNY as I get a bit of slow down shooting raw occasionally
Buy whatever suits you best. If you have breaks in your shooting style that allow for swapping cards, two cards may be the way to go. If you are shooting high paced events that don't allow a lot of time to swap card, or if you are good at losing small items, one card may be a better choice for you. I know as many photographers who have lost pictures by ...
Came to confirm that the Micro SD card 256 GB can be used through the adapter to the SD card with the Canon 5D Mark iii camera and can be formatted within the camera. Tested the shooting and brought it to the PC, okay, both raw and jpg.
Should be firmware because in terms of hardware they are physically the same. That of course doesn't mean that a company will ever actually release the needed update.
As an aside, I teach photography and am a professional artist and would suggest that for almost all uses, SDXC cards aren't a good idea (time-lapse being the possible exception). The problem ...
I had the same issue. It is a possibility that you have indeed some hidden files. To delete them you should format your storage card.
On a canon you can do that in the menu.
Click on the menu button
Go to the wrench icon which is displayed on an orange background.
Go to format
Enter it by clicking on the set on your camera
You can choose to do a low ...
The clue is in the title of the support article which is "What memory cards have been tested for use in the Nikon D3100?" and not "What memory cards have known to be incompatible with the Nikon D3100?"
Nikon are not saying that the 32GB SanDisk cards (SDHC/SDXC) are not compatible, only that Nikon have not tested them.
SanDisk appear to have tested their ...
Macs place a hidden file and folder on mounted volumes. The file is always small but if you delete files from the card using Finder then they will end up in .Trashes until the the trash is emptied. Some other possible reasons might be you have done some kind of move or copy/delete, or copied something to the card, or maybe you never formatted the card when ...
