CF SD adapaters

I've got a xsi, and a bunch of sd cards. I am looking at a 7d, which uses CF. I plan on keeping the xsi - sometimes it is just too handy to have 2 bodies with different lenses.

I'm bummed that they use different cards. Just one more thing to keep track of. Not a huge deal - but who needs it?

I'd like to hear from someone who has first-hand experience with the cf-to-sd adapters. The sd card fits right inside a cf footprint which then goes in the camera - in this case the 7d. The reviews are all over the place, regarding speed.

Any experiences you could share would be welcome.

Oh dear. Not much use I’m afraid. I got one as an emergency, emergency backup as I carry SD cards for various family pocket cameras and my S95. But alas, I haven't actually used it as the emergency, emergency hasn’t happened yet. I think people use them to put an Eye-fi card in.

Why not a 60D instead of a 7D? Unless you're going to be shooting things that move a lot (sport and/or wildlife) there's really not too much difference. And the 60D uses SD.

Yeah - I'm on the fence. Sports and wildlife pretty much describe my subjects. Add low-light as well.

The adaper cards work very well. A big cost and space saver.

I use the eTECH SD SDHC SDXC to CF / Compact Flash Type II Adapter[/URL] to adapt my Eye-Fi Pro X2 8 GB[/URL] to my 5D Mark II (which is capable of UDMA, which is the wider card type) and it works great (7D has UDMA as well). The speed when taking multiple pictures is great, go about 8-10 shots with RAW+small jpeg before it has to catch up (not upload speed, but just getting shots onto the card) After that the eye-fi manager is able to download them via wifi-n at about 5ft from the camera to the wifi dongle i have at about a 1mb per second transfer rate and if it's right next to the N-dongle it will be about 1.5MB per sec.

A demo using the etech cf card adapter I mentioned and the 5d mark ii transfering to the ipad has been posted on vimeo

I have one of the El-Cheapo adapters from an eBay seller, and it does
exactly what it's supposed to do, from 2GB SD cards to 16GB SDHC cards,
in both my Rebel XTi and my current 40D. I think I paid about US $18 for it.

For SD cards up to 16GB, make sure the adapter is rated as being compatible
with SDHC cards, and for SD cards over 16GB, make sure the adapter is rated
as compatible with SDXC cards. For SD cards of 2GB or lower, any adapter will do.

I don't shoot much high-framerate stuff, so I can't comment on how well the
adapters do with speed of data transfer, though I've heard that most of them
are fine even for full-HD video on the newer cameras.

I'm considering picking one of these up for my upcoming month long trip that I need extra storage for and need to stay on a budget. My only concern is that I've read in a few reviews that it reduces shot to shot time (I'm shooting with a 40d). Is this possible, won't it just slow down how quickly the buffer restores?

Hmmm, I have a SanDisk Extreme III 8GB SD card that I bought a few months before I upgraded from the XSi to the 7D, one of these adapters might not be a bad idea.

Just in case I fill the other 56GB of CF storage I have... lol

I have the PhotoFast CR-7000

Just curious - on the 7D is it necessary to remove the adapter to change the SD card? Or can you swap the SD card in and out of the adapter without removing the adapter itself?

trade in the XSi for a refurbed 7D. Then no more slow SD cards. Step up to fast CF cards.

based on the image in the post above yours, I'd say full removal is needed

I have an adapter and it certainly works but it does seem to have a slower shot-to-shot time for sure and seems to be okay on low speed continuous but not so good in high speed mode. Of course none of this matters until the buffer is full, after that then card speed will have an effect to a certain point, although I only have class 6 SD cards no class 10's so that may be the issue more than the adapter. The 7D can write at speeds around 40 MB/s or so, maybe I should try a class 10 card in the adapter and see if that helps.

I bought the Delkin one from B&H which is now discontinued. For anything that I want a high frame rate I do not use the adapter, for other shots where high FPS is not an issue it is certainly fine.

Most of the cards I've seen and the one I own require removing the card to swap out the SD card.
