Eye-Fi has added a new high-end Wi-Fi card for digital cameras, updated its software, and added an auto-delete option: I've been a fan of the Eye-Fi, a Secure Digital (SD) format memory card with Wi-Fi embedded since its release. But I've always had some nits to pick about how it works. Over time, Eye-Fi has addressed most of these.
The last appear to be resolved in the release of new software, and a new high-end card, the Pro X2. The software is available today, and pre-orders for the Pro X2 are being taken online now.
The Pro X2 (list $150) shifts its Wi-Fi to 802.11n, almost certainly the single-stream variety, which improves range and speed separately and together. The card includes 8 GB of storage, and is rated Class 6 for its read/write speed. This is a leap from 4 GB with its Pro card (see a comparison of all Eye-Fi cards).
The card supports all the Pro options, too, including ad hoc Wi-Fi connections, RAW downloads, hotspot access for 1 year, and Wi-Fi position-based geotagging. The Pro was formerly $150; the new pricing wasn't available as I write this.
Coupled with the new card is revised software for working with the Eye-Fi. Until now, Eye-Fi has relied on agent software that creates a local Web server for handling configuration. The new software is a desktop application, which among other features will let you publish photos to multiple online locations simultaneously instead of choosing a single photo or social-media site. All Eye-Fi owners can use the new software.
Eye-Fi also introduces a new feature the company calls Endless Memory, and which I would describe as "delete as needed." The original Eye-Fi firmware would upload all JPEGs. Later revisions added models that handle RAW and movie files, as well as giving all user selective uploads. (You use the protect or lock function on your camera to select images for the Eye-Fi to upload.)
Endless Memory adds the final missing piece, which is automatic deletion as necessary of verified uploaded images and movies when space is needed for new material. For a photographer with a hotspot subscription or a laptop nearby for uploads, you could shoot, well, endlessly.
