The most known name is Eyefi, which has a pair of SD card options: Mobi and Pro
X2 . (Now if your DSLR camera uses CompactFlash instead of SD cards, you can go
for an adapter.) Most cameras are compatible, although if you have an Eyefi
Connected DSLR camera (of which there are many) you get added features such as
the ability to turn the Wi-Fi radio on and off, and to select and prioritize the
images you want to are transfer.
The Mobi card is the simplest to setup and use: just download the Mobi app to an
Android or iOS device, put in the activation code supplied with the card, and
you're basically finished. With the app open you can begin taking photos, and
the card will connect with your device and begin transferring images to it.
Also, you can also use a Windows or Mac desktop application to convey images
direct to a networked computer. The card will only accept JPEG transfers along
with video formats supported by your computer, phone or tablet.
In addition to Eyefi, there is the FlashAir card from Toshiba , which works a
little different than Eyefi's. Instead of just establishing a single alliance
between the SD card and your computer or mobile device, the FlashAir acts like a
hotspot, allowing as many as seven wireless connections at the same time.
One advantage of the FlashAir card is that after a device or computer is
connected, you only need to open a browser window to see the images on the card.
Also, a FlashAir II card firmware update provides an Internet pass-through
feature, allowing your mobile device to still connect to a normal Web-connected
However, the cards won't automatically send your images to your device: you'll
must select the shots you want and download them from the card to your tablet,
smartphone or computer.
You can look at the list on Toshiba's site if you want assurance the your camera
and the features you're looking for are available, however the cards are
compatible with most cameras.
A Flucard installed in a Pentax K-3 turns your tablet or smartphone into a
wireless remote viewfinder and controller.
In addition tj the two above there is Trek 2000's Flucard (there's one made
specifically for Pentax cameras that lets you to remotely control your camera
using your smartphone) and Transcend's 32GB Wi-Fi SD card . Judging by user
reviews, they seem a little hit-and-miss.
One last option, Monoprice and some others offer a microSD-to-SD card Wi-Fi
adapter. It seems to function similar to the FlashAir cards by establishing a
hotspot that as many as five devices can be connects as if they would to a
typical Wi-Fi network. Then you simply point to an address in your browser to
view and download images.
You can use your own microSD card as large as 32GB is supported), so you're not
constrained with a single size. And using an adapter could be a bottleneck for
high-speed photography, however if you just require a simple solution, this
could be your best bet (and the least expensive, at under $40).
aren't too many options when it comes down to wireless accessories offered by
the camera manufacturers themselves. In fact, there are only a few models from
Canon and Nikon.
Nikon, offers the WU-1a/WU-1b. This tiny dongle plugs into the Micro-USB port
(or Mini-USB port on the 1b) on your camera, and you can then turn it on using a
menu setting. You can connect this device using your Android or iOS device
simply by selecting it from the Wi-Fi settings on your mobile device.
Using the Nikon Wireless Mobile Adapter Utility app you can see the images and
videos on DSLR or ILC and move them to your device. You can also employ the app
to act as a remote shutter release and viewfinder.
The adapters cost around $60, although you can often find them for less. All
they do is transmit to mobile devices, so if you need to wirelessly send shots
to a computer you'll require something else. Nikon has professional solutions
for this, although they're closer to $1,000 than $100.
doesn't offer a mobile solution such as the WU-1a/b, only professional
transmitters for the Canon EOS-1D X, 5D Mark III, and 6D. Additionally, there
also transmitters available for older model Canon DSLRs, too, although they all
cost hundreds of dollars. If you can go the DIY route, do a Web search for
installing Wi-Fi to a Canon DSLR and you'll find a few interesting solutions.
There are a few third-party adapters that deliver quite a bit of functionality
without being over the top expensive.
The CamRanger , iUSBportCamera and Weye Feye are currently the chief options
available. They function about the same, too, allowing you tether a Canon or
Nikon DSLR to your Android or iOS or tablet or phone or to a computer.
Connect one of these to your camera's USB, turn it on, and you can establish an
ad-hoc network among it and your mobile device or Windows or Mac computer by
choosing them in your wireless network settings.
Once a connection is established, you can use the free Android or iOS app to
take control your camera's settings, see a live view from the camera (if it has
has live view), tap to focus, and press the shutter release.
You can set them to automatically transfer images to your device, or you can
just view the images you've captured. The apps also feature a bulb mode, an
intervalometer, HDR bracketing, self-timer and macro photography controls.
The $300 CamRanger appears to be somewhat more polished compared to the
iUSBportCamera, but the latter also cost around $100 less.
The Weye Feye weighs in at around $100 and falls under the CamRanger
and iUSBportCamera, and can essentially provide the same things such as full
control over the camera using a mobile device. It, too, only works with Canon
and Nikon DSLRs. although, the company is working on the Weye Feye S which will
work with DSLRs and ILCs manufactured by other camera companies and allows you
to wirelessly see and transfer images and videos among cameras and Android and
iOS devices or anything featuring a Web browser.
