unfocused said:Trying to add a touch of sanity to this.
The car battery analogy is not a good one. Better would be fuel. Consumers have choices of fuel, but government regulations dictate standards that assure that fuels can be used in all brands of vehicles. So regulations that dictate standards that allow for backward and forward compatibility isn't necessarily a bad thing.
But, this role is already being performed by the industry itself, so no real reason for government interference. SD Cards are the best example. The industry has done a really good job of making them backward compatible, which is always the major risk/concern.
Reducing the various types of cards sounds good in theory, but who is going to tell all the people who own cameras that use a "banned" card that their cameras are no longer supported?
There really isn't that much variation in cards. I don't know why it should be a problem. Most enthusiast and pro cameras use one of four types: SD, Compact Flash, CFast and XQD. Compact Flash seems to be dying a slow natural death. New players like ProGrade are not making CF cards (only CFast and SD). Finding CF cards in stock seems to be getting harder. But, I certainly want them to be available as long as possible, so that I can continue to use them in my 5DIV and 7DII.
XQD cards were a gamble that will likely negatively impact Nikon and Sony owners, but have no effect on Canon buyers. Good for us that "stupid Canon" was smart enough to use CFast.
The market may eventually settle on CFast and SD as the two most widely used cards for photography. Not sure why that would be "too many standards."
SD and micro-SD.... they are in everything! I can pull a micro SD card out of a GoPro, put it into just about any p/s camera, snap some pictures, put it into any Rebel, shoot some more, put it into my 7D2, shoot some more, pull it out, and plug it into any laptop, or into my TV to view the images, or through an adapter and edit on an iPad....
And of course, there is now the high speed version (UHS-2) with the extra pins that is still backwards compatible but allows speeds like CF....... this is a standard that is here to stay!
