Do CF/SD Adapters Cause Instability?

So I got my Canon 5D Classic about a month ago now.
Prior to that I was using Panasonic Lumix cameras, and they all used SD cards.

I figured that getting a SD to CF adapter so I could use these SD cards with my 5Dc would be a better idea, so I have more back up cards for each camera instead of having two different categories of cards altogether.

However, from the beginning, I was wary of one thing: instability and data corruption.
I can tell these SD to CF adapters arent just dumb adapters (like microSD to SD adapters), but they have some sort of logic built in (right?). So I'm thinking... I know my card itself is from a reputable and reliable brand, but I couldnt find a single SD/CF adapter that was from a brand I've heard of before.

I took the risk anyway since the adapter was like 10 bucks from B&H.

Once in a while I did run into data corruption. Sometimes a single image wouldnt save correctly, so when I went back to review it in camera, that image would be unviewable. Or sometimes an image doesnt get saved at all... But this was only for 1 in every 100 pictures.

Didnt think it was a big deal...

Then yesterday, my girlfriend is using my camera and suddenly she goes "Hey it says folder full, and it wont let me shoot"
No errors or anything.. just folder full... I checked the camera settings, its set to continuously number and create new folders.
So I popped the card into my laptop, the DCIM folder is there, the 105EOS5D whatever folder is there, but there are no pictures inside of it.

The computer still shows that about 200MB of the card is occupied, but I found no pictures.

I run chkdsk w/ the option to scan and recover bad sectors. At the end of the, the 105EOS folder just became a file. An extension-less file.

Not sure whats going on...
I asked my girlfriend if she accidentally shut the camera off or popped open the CF card door while shooting and she said no.

Is this an issue with the CF adapter or is it just bad luck + old technology acting up?

Why are you even asking about this? .. I'd have ditched this setup (actually never bought it in the first place ;) ) as soon as it played up. Everything I've bolded above would make me run a mile from it.

Just buy CF cards .. way better, way faster, way more reliable .. plus solid piece-of-mind

Good Lord, CF cards (2-4 gigs) are like $10-15 at WalMart.


....the best camera is the one you have on you at the time.

Buying a $10-15 CF card would probably land me in the same situation. Plus, no Wal Marts in NYC :P

Anyway, yea I was suspicious at first too, but I've learned that money isnt the best judge of everything.
The adapter also had good reviews on B&H, Adorama, Amazon, etc, and I couldnt find any issues about it via google.

Also, the 5Dc is 7 year old technology, so for all I know its an issue with my camera.
Again, the data corruption issues were very rare. I can only recall it happening with two images in the past month. Not counting the fubar moment I had yesterday.

This is why I'm asking about this here. I'm hoping to hear from someone who has used this kind of thing before.

SD is just so much more convenient for me. My desktop and laptop have SD readers but no CF. My LX3 and G1 also use SD cards, not CF. Go to any household or office and take a look at the computer, probably has a SD reader but no CF.
Thats why I'd prefer to have a SD card instead of a CF card.

More appropo analogies:

VHSC adapter so you could use your camcorder tapes in a VCR....
8 track cassette adapter so you could play tapes on an 8 track system...


As others have stated, just get CF cards, it is much better overall to stick with media designed for the memory port in question.

$16 for a 4gb Ultra from Amazon...

Or $18 + NYC tax at B&H if you want to stay local.... There is no issue having multiple types of cards, card readers these days read about any kind of card.

I remember a 8track player sticking out of my grandad's tape deck in his Cadillac. Quite the sight!

Every time you use an adapter for a media card like Micro SD > SD > CF, you cut your data rate and risk data loss.

Damnit lol
Alright thanks guys, guess I'll be getting a CF card.
Just gotta decide between a 8GB Ultra or Extreme now lol.

Slightly OT, do any of you know of a "mountable" CF card reader? Like something I could just screw onto the bottom of my desk. If not, yea I'll probably just have to DIY something to mount it.

re: mounting cf reader, i used double-sided tape. but be careful on the reader, some of the cheaper ones it's hard to line up the pins, so if you're not careful you can end up bending the pin on the readers, in a worst case scenario you could break a pin inside the card and then try to put it in your camera!

i have a finicky one and i always make sure to line it up in my hand when i load a card.

there were "mountable ones" for a floppy disk slot years ago, but I have no idea about now days when computers don't even have floppies anymore.

Get the ultra, the difference is negligible in speed, but sure is apparent when it comes to pricing. I use a couple of Ultras, they work like a charm.

Interesting thread! We just decided to buy CF cards today when we purchased a D700. We didn't even known SD/CF adapters existed.
