Pretty much as what the title asks. Any ideas anyone?

EDIT: Is there any particular, technical limitation for using this technology with CF cards?

On Eye-Fi supporting CF cards, I think it would be best to ask them. On the alternatives, I don't suppose you tried using an Eye-Fi in a SD-to-CF adapter? No other options come to mind. –  Itai Jan 24 '11 at 16:17
@Itai - I dod not try an adapter, and from what I have read they are limited in their usability. I hope maybe one of the forum member has actual experience with using such device in his CF only camera, so we can all learn from a 1st hand experience. –  ysap Jan 24 '11 at 16:24
My understanding is that the adapters work best when shooting JPEG, that trying to shoot raw usually results in failure. –  John Cavan Jan 24 '11 at 16:28
Edited to make the question answerable without having to speculate about EyeFi's business model. –  Jay Lance Photography Jan 24 '11 at 18:02

Here is the latest answer on CF adapters for the 5DmkII and the 7D, on our site.

Ziv, would you mind adding a quick note summarising this discussion, just in case this link to your forums breaks in the future? –  Maynard Case Jan 25 '11 at 9:15
thanks for your input. So I saw there the link to Amazon. One question still - regarding the working mode with the Eye-Fi device, is it for on-the-fly file transfer or can it wirelessly transfer files after the session is over? That is, do I need to have my computer around while shooting? –  ysap Jan 25 '11 at 9:15
while we're at it, can you comment on why Eye-Fi does not support CF? –  ysap Jan 25 '11 at 9:17
to follow on from @Maynard's point -- don't forget that some over-jealous filters will block anything with "forum" in the hostname, which makes your answer unreadable. –  Rowland Shaw Jan 26 '11 at 17:15

Thus far, Eye-Fi does not support compact flash. They have a page on their website that lists known issues when using an adapter. These issues include a reduced wireless range of the Eye-Fi card as well as a potential for file corruption.

I'm not aware of any competitor's products which offer similar functionality in a CF card. I do note however that it seems DSLR manufacturers are starting to move to SD from CF, with newer models from both Canon and Nikon favoring the SD cards.

@ahockley - yes, I have found that page on their website. I was wondering if there is a particular reason why they do not support CF. –  ysap Jan 24 '11 at 17:27
If you want the true reason from the company, you'll probably get a more accurate answer by asking the company than by asking here. –  ahockley Jan 24 '11 at 17:48
How would anyone here on photo.se.com know the answer to 'why'? –  Jay Lance Photography Jan 24 '11 at 18:02
@Jay Lance Photography - the intent is to ask about the technical reason, not their business model/decision. Anyway, I accept your edit. –  ysap Jan 24 '11 at 18:11
@yasp more likely is the commercial viability -- SD is defacto for consumer cameras and entry levle DSLRs which gives a wide possible audience. CF is generally used by higher level cameras and most of those support tethered shooting which would eat in at the people wanting the product. –  Rowland Shaw Jan 24 '11 at 18:22

Jesse Rosten talks about just this set up in his blog; http://jesserosten.com/2010/wireless-tethering-to-ipad

Cool article. I'm going to try that setup. Thanks! :) –  AJ Finch Jan 26 '11 at 12:10

I strongly doubt there's a technical reason. I'm sure that they just don't see offering a CF version as profitable.
