EyeFi Updates Its Mobi Pro Line with RAW Syncing

By Anthony Thurston on March 12th 2015

In this day and age of cheap storage, it honestly feels weird needing to use more than a single card for storage during a shoot. Cards are getting bigger, faster, and most importantly – cheaper. But that doesn’t mean that it isn’t still convenient to be able to get your RAW files off your camera wirelessly.


EyeFi has announced their latest edition to their Mobi line, the Mobi Pro. Its headline feature is the ability to transfer RAW files wirelessly from your camera to your phone or computer via WiFi. Your camera may already have WiFi built in, but in my experience, most of these built in solutions limit you to Jpeg transferring, so to my knowledge, if you want to transfer RAWs, EyeFi is currently your only option.

EyeFi Mobi Pro Specs

  • 32GB Storage Capacity
  • Class 10
  • Max. Read Speed: 13 MB/s
  • Max. Write Speed: 23 MB/s
  • Built-in Write Protect Switch
  • 802.11b/g/n Wi-Fi Compatible
  • 2.4 GHz Operating Frequency
  • WPA/WPA2-PSK, WEP 64/128 Wi-Fi Security
  • Up to 90′ Wireless Range

Personally, I can’t really see myself needing to transfer RAW files wirelessly. I mostly use Wifi to get shots off my camera to my phone for going straight to Facebook, Instagram, or Twitter – not to be edited right away. That said, I could see this being utilized as a sort of secondary backup solution, so all of your images are also backed-up off your card/camera in case they are lost or stolen, or in some way damaged.


The EyeFi Mobi Pro at release will only be available in one flavor; A 32GB Class 10 SD which will retail for $99. If you would like to take full advantage of the Mobi Pro’s backup potential, you can also sign up for their cloud syncing/storage feature service, which allows you to send your RAW images from your phone to the cloud to be stored. The cloud service will be available for $49.99 a year for unlimited storage (after your initial 1 year of free storage included with your purchase of the card).

If you are interested, you can get your hands on the new EyeFi Mobi Pro now over on B&H. They are in stock and shipping right away.

    this just still feels gimmicky more than true puposeful

    Wireless upload is fine, but I don’t see a big advantage if it’s not coupled with wireless control. Basically, wireless tethering is what really needs to be out there in a big way, especially on pro bodies.

    Other options –

    For android users – there is USB OTG (or similar) – which allows you to marry your device with your camera – the basic function allows for export of RAW or JPEG etc, off to the phone / tablet –

    once the images are on the phone – typically stored under /sdcard0/DCIM/* – you can use “ES File Explorer” (free!) which also has FTP / LAN / WAN capabilities to offload the images to ANYWHERE local / across the net (depending on phone’s WIFI speed capabilities in tandem with your network – I have had speeds up to 10MB/Sec – not terrible)

    USB OTG (On The GO) – if part of the phone’s / tablet’s make up, this is viable – there is a physical adapter which plugs into the micro USB of the device and the other end into the camera – price, typically $3 – $4 dollars

    I use this in conjunction with my D810, works just fine – it’s not onboard, but the cost is so low (for the part) it makes sense to do, and the speeds are not lightning, but capable / doable…

    For Apple – Using a “Apple® – iPad™ Digital Camera Connection Kit” – can work too, if there is a complimentary file transfer program which can do the same FTP / WAN / LAN file transfer capabilities –

    Use Case – out in the field / on site etc, photographer plugs device into camera – transfers images to device (iPhone / iPad / Android) and uses software to complete file transfer using hotspot to PC / Server or uses cell phone’s data connect (high data rates / charges may apply… :) )

    This, obviously is not eyefi – but a viable alternative – which also suffices as a reasonable alternative to proprietary WIFI options provided by a camera MFR – which have a tendency to NOT provide faster transfer BUT are very very very cost prohibitive for some…

    I have owned eyefi – it was shoddy at best, neat concept, not professional –

    Yeah, I find my eye-fi mobi extremely useful. Fragile, but useful. I use it everyday. However, there’s no way I’d want to deal with RAW file transfers. It’s good to know the technology exists if necessary though.

    good way for photojournalists to get their photos off camera as quick as possible. especially when covering events where they may be harassed or forced to delete content by law enforcement.

    I use a eye-fi card when shooting events for the reason of posting to the clients Facebook etc… they love the idea of ‘real time’ posting with a few words. So having the camera record to the SD in S2 JPEG is great for file size, goes to my iPhone nice and quick too.
    I’d have little time for raw transfer as I found it slow (on my 70D anyway).

    Per the article: “Personally, I can’t really see myself needing to transfer RAW files wirelessly. I mostly use Wifi to get shots off my camera to my phone for going straight to Facebook, Instagram, or Twitter – not to be edited right away.”
    I don’t know…I just heard an interview over at at with a BYU sports photographer who’s talking about the speed at which he can take shots (currently JPEGs), get them wi-fide to a portable, make-shift server and then sent from there to his editor, who can quickly edit and upload them to any site desired (social networks, news, etc.). With RAW transfer, that would be mean that much more control over the editing, omething that might be very feasible.

      I agree with you , but the bottleneck is the speed with which RAW files are transferred. Jpegs are much smaller, and therefor much faster to send wirelessly. RAW is a different animal, and based on how slowly the RAW files would be transferring, It don’t seem much use in the field, especially for something like sports where time is of the essence.

    I think I’d prefer a wireless hard-drive with SD slot.
