Even though most new cameras have integrated Wi-Fi, you may be shooting with an older model without that feature, or you may simply want to forgo the process of using an app to select and transfer photos and opt for something more automatic. Eyefi has been making connected memory cards for years, and its latest entry into the field, the Eyefi Mobi Pro ($99.99, 32GB), is the best one yet. It combines the ease of use of the Mobi ( at Amazon) and merges it with the robust feature set of the X2 Pro , making it an easy pick as our Editors' Choice for connected memory cards.

Features and Operation
At its heart, the Mobi Pro has one basic function: to transfer images from your camera to your smartphone, tablet, or computer wirelessly. There are several cases in which this can be useful. You can use the card to copy images from your camera to your phone while you're out and about, so you can share an image on Instagram, email a photo to your Mom, or do anything you'd normally be able to do with a photo that was captured with your smartphone. A hard plastic card with the code required to install the card's profile onto your portable device is included.

With the regular version of the Mobi card, any JPG photo or video clip that was captured would transfer automatically to the free Eyefi Mobi app for iOS,  Android, or Windows Phone. That's the default behavior of the Mobi Pro as well, but you can reconfigure the card to enable selective transfers. You'll just need to plug the card into a Mac or Windows PC (an SD card reader is included in the box if your laptop or desktop doesn't have one built in), and enable selective transfer via the Eyefi Mobi desktop app.

If you're like me and you use an Eyefi card with a camera that lacks Wi-Fi while traveling (or covering a trade show for PCMag), selective transfer is a huge plus. Instead of offloading the dozen photos I've shot in the past hour, I can pick the images I want to share socially, flag them, and they'll copy over. With most cameras, you flag photos by marking them as protected or locked via your camera's playback menu. I ran into one exception to this method while testing the card; the Ricoh GR ($970.95 at Amazon) has a function in its playback mode that allows you to select individual images for Eyefi transfer. But with the other cameras I used to test the card—the Canon EOS 7D Mark II ($1,199.00 at Amazon) , Leica M (Typ 240) ($2,969.00 at Amazon) , and Canon PowerShot Elph 170 IS ($149.99)—all use the Protect Image function to flag photos for transfer. Both the mobile Eyefi Mobi app and the Mobi application for Windows and OS X respect selective transfer.

The Mobi Pro can also copy Raw images, but only to the desktop app. This is another function that's turned off by default; again, it's easy enough to enable this function, you'll just need to check a box in the desktop app's configuration screen. The only real issue with Raw transfer is the time required to copy each file over Wi-Fi—it took a few minutes to copy over half a dozen Raw files from the 7D Mark II to the MacBook Pro I was using for testing. It could come in handy if you're traveling with a compact laptop that lacks an integrated memory card reader and want to transfer a Raw image over for editing. But if you have an SD card slot in your computer, you're better off using that. Regardless of the speed, I was happy to see that the Mobi Pro was smart enough to copy a Raw image to my computer, even after the JPG version of the file had been copied to my iPhone.

Some older Eyefi cards, including the X2 Pro, could work on your home network, but you'd need to plug the card into a computer and reconfigure it if you wanted to set it to broadcast its own SSID for transfers to a portable device when you're away from home. The original Mobi only worked this way, so if you wanted to copy an image to your phone while you were sitting in your living room, you'd need to go into your phone's settings and manually switch networks.

The Mobi Pro is smarter. The desktop app comes into play again; you just need to register your home network and password once. Once that's done, the Mobi Pro will automatically sync up with your home computer or smartphone when you're at home, and it will broadcast its own network for your smartphone to connect to when you're away from home. You won't have to reconfigure the card each time you want to change its mode; it's all automatic.

Eyefi Cloud
You get a one-year subscription to the Eyefi Cloud service when you purchase the Mobi Pro. That's a $49.99 value, and can house an unlimited number of photos. Cloud also works to sync images across multiple devices. If you copy images to your smartphone, they'll be uploaded to your account and automatically download to other devices with the Mobi software installed, including computers, tablets, and other phones.

Eyefi Cloud also works to save space on your phone. Once the full-size images have been uploaded to Eyefi's servers, they are resized to match the screen resolution of your phone and downloaded back to your device. Full resolution images are kept in cloud storage and also downloaded to your computer, so you won't lose your original images. Full-size JPGs are kept in cloud storage for as long as your account is active, and Raw files are kept for 30 days.

And Eyefi Cloud does more than just store your photos. You can tag images (they'll also populate across devices), create albums and share them with friends and family, and set up If This Then That (IFTTT) recipes to sync images with other services, including Flickr, or pull photos from your Instagram feed and store them in your Cloud account. The service can work independently of the Eyefi hardware. If you want to use it as your primary online gallery, you can go as far as to set up a watched folder on your PC and export processed and curated Raw images that are exported from Lightroom so you can access them from handheld devices.

Performance and Conclusions
If there's a downside to the Mobi Pro, it's speed. If you're shooting with a pro-level camera in burst mode, you'll be frustrated by image write times. I used the 36-megapixel Nikon D810 ($1,996.95 at Amazon) in Raw+JPG mode to see how the Mobi Pro stacked up against a SanDisk 95MBps SD card. The Mobi Pro is able to capture 17 images at 5fps before the D810's buffer filled, and it requires 55.6 seconds for the buffer to fully clear. The SanDisk card manages 19 images at 5fps, but it only needs 16.2 seconds for the buffer to clear. That's a big difference when you're shooting in the field. It's less of an issue with a pro body with dual card slots—you can use the Mobi Pro for JPGs and use fast CompactFlash memory for Raw files—but it's still a downer that it doesn't perform as well as the SanDisk memory in terms of speed.

Speed aside, the Eyefi Mobi Pro is a winner. Out of the box, it behaves just like a standard Mobi card. And, while its $100 price tag is a bit high for a memory card, it doesn't carry a premium over the standard 32GB Mobi card. In the year and a half that I've been using the Mobi card in my non-connected cameras, the ability to pick and choose which images are copied over to my phone has been my number one want. The Mobi Pro adds that function, works just as well on my home network as it does when I'm out taking pictures, and supports Raw transfer to OS X and Windows. It also includes a complimentary year of the Eyefi Cloud service, which is quite slick and especially useful if you install it on multiple devices.

Most importantly, the Mobi Pro just works—you won't have to spend hours setting it up. After the initial setup, the only time you'll need to configure it via your computer is if you want to toggle the selective transfer function. If you're in need of a solution to copy images from your camera to your smartphone, look no further. The Eyefi Mobi Pro is the best connected memory card that I've used to this point, and an easy pick as our Editors' Choice.
