アップル Lightning - USBカメラアダプタ MD821ZM/A
Apple Lightning to USB Camera Adapter
Generally, good quality.
It is possible to use this adapter for other than the tasks listed by Apple. For example, to connect an iPhone to an iPad and transfer photos and videos shot with an iPhone into an iPad - where editing is much better on the bigger screen, Be aware, though, that you cannot transfer files in the other direction, i.e. iPad to iPhone.
If a powered USB hub is used, then some devices requiring power through a USB connector may work. For a comprehensive review of the possibilities with an iPad, try a Web search for "Going beyond cameras with the Apple Lightning to USB adapter".
It is very expensive (and about double the price of the older 30-pin connector kit).
Only 12 cms overall length, of which only about 5 cms is the flexible cable between the connectors. More length might have been better to reduce possible strain on the Lightning socket on the Apple device. It begs the question: Is this better than having a solid block adapter with no cable between the connectors? There are advantages and disadvantages for both types.
It is proprietary to Apple so cannot be used on phones and tablet devices from any other manufacturer.
Probably of limited useful life due to Apple periodically change the connectors on (especially mobile) devices, so expensive Adapters like this will eventually become redundant with some future new models. (Rather annoyingly, this sort of change has left me with a now useless stock of old and expensive 30-pin adapters after upgrading my Apple mobile devices.) It remains to be seen if Apple changes the connectors on the mobile devices yet again given that they have moved to a single (new standard) USB-C port on the new MacBook. However, this may not happen on Apple mobile devices because USB supports the supply of power to a connected device, and this is a potential drain on a device such as an iPhone. (BTW, for an in depth look at the history of these connectors try searching the Web for "Ross Rubin" and "Apple And USB A History Of Adoption Acceptance, Acquiescence".) However, the future may well be for Apple to remove wiring port connectors entirely from their devices, even for charging!
As with a number of Apple-only accessories, one has limited choice if the function is required. It's the price you pay for the wall-garden "protect/control the consumer" approach currently used by Apple.
I also have a Canon 70D and this uses SD cards - to copy these to an iPad you can use a direct connection - a small device that connects to the Lightening socket on the iPad with a SD card reader built in. No reliable (at least that I could find) unit is available to do this for Compact Flash cards as I understand they required much more power than SD cards.
Basically an extremely overpriced USB otg cable, apple really do treat their customers like cash cows. Didn't work with our Sony camera but works OK with a 5 slot memory card reader and a Nikon d5200 albeit with an extremely slow download speed. The only reason I bought an iPad air 2 after years of using android tablets and phones was for the high quality image and audio editing applications available on iOS. Once the files are in the iPad it's plain sailing but getting them in and out are such a pain in the a*** it's almost making me reconsider the iPad purchase.
The fact there is no file explorer on iOS just make the problems worse. At home I end up using a £2 (!!!) USB otg cable and card reader to quickly put pictures on my nexus 5 then use an app called send anywhere to transfer them over my WiFi network to the iPad.
Also it won't download duplicates of images so I end up with only jpegs and not the RAW counterpart! There's probably a solution to this asides from shooting solely in RAW but I've not researched it yet.
Away from home it looks like I'm stuck with this partially broken and restrictive hardware solution.
Once imported you can select to delete or keep photos on camera. The imported photos go straight into Camera Roll, then can be shared on Facebook/Instagram, which was the idea I had. Very fast to import, have done 3 photos at a time and only took about 3-4 seconds total, not bad!
Yes; expensive, there might be alternatives, but this 100% works as I wanted it to, so its worth the money
It also works well with Roland UM-ONE mk2 USB MIDI Interface.
For the £25 it would have been nice to have some information on which devices/specifications are "officially supported". Apple call it a "cameral connection kit" which is a bit of a cop-out. This means that if you want to do more than just connect a camera (who would bother to pay £25 for that privilege?) only trial-and-error will tell you if it works with your particular hardware.
However the thing that is the most surprising is the seller, the poor guy got about 15 emails from me in order to solve a problem that I caused, and by the end of it, they decided to give me free of charge a new product, what an amazing seller.
If you are going to run one of these applications, the cheap chinese knock-offs are hit and miss, usually miss. Unfortunately we have to buy this Apple adapter, but it works, so that's worth the extra cash. Don't even waste your time with the third party ones.
