Initially the reason was performance and capacity. A lot of the pro-level cameras went CF because you needed the performance and, usually because a pro shoots RAW, the capacity which the original SD couldn't match. Not to mention there was a point in time where SD was more expensive as a result of volume sales differences. SD is now cheaper thanks in a big ...

Mostly because CF has faster read/write speed than SD card. SDHC has a higher capacity (more space) but not necessarily faster read/write speed. Some high-end CFs allow parallel read/write (the interface allow this), but not SD/SDHC. So some high-end camera usually take advantage of this in combination with their buffer. Now Rob Galbraith did lots of test ...

No. None being manufactured anymore. The last one was the Fuji Finepix S9000. Believe me, I understand where you are coming from. Memory used to be a big investment, it was $1100 CDN for a 1 GB CF when I purchased one in 2002. Because of this, it was important when changing cameras that you could continue using the same cards. This is no longer the case. ...

I have a Canon EOS 1Ds mark 1, and I have recently put in a 32GB card. It is true that in-camera formatting only allows for an 8 GB partition to be created. However, if I re-partition the card on my computer and create a 32 GB partition, the camera will recognize all 32 GB. I have tested filling the card beyond 8 GB, and it still seems to work in the ...

And since this thread has now been resurrected, I'd like to add another reason that I'm surprised nobody has mentioned. Pro cameras tend to use Compact Flash because pro photographers prefer the size of Compact Flash cards. They're bigger, easier to handle with gloves on, harder to lose. They're also perceived as being tougher due to the size. Whether or ...

I found myself in the same boat about a year ago, and I considered picking up an SD-to-CF adapter to use SD cards in my camera. All the research I did, however, showed really spotty results for these adapters, so I bagged that idea and bought a couple CF cards and a USB card reader for the CF cards. The ultimate driver for me was reliability. At the end ...

Some professional DSLRs do support SDHC, such as Canon's 1Ds Mark III. Historically, Compact Flash offered higher capacity with miniature hard disks, although with advances in flash memory, solid state media has long overtaken it. Manufacturers don't want to give any excuse for photographers from upgrading, so tend to carry on supporting CF.

I guess in part because CF cards are bigger, and so it's easier to develop faster and larger quantities of memory in large-sizes, before scaling down to the smaller SD cards later on. I think the added bulk and resilience of the more substantial CF cards. I'd imagine most of the professional camera body users also have a fair amount already invested in CF ...

I can't find any specifics for the 7D that are helpful. Normally I would look to the Rob Galbraith CF/SD Performance Database, though the newest cameras aren't listed there. According to the dpreview.com 7D review's performance section, the camera maxed out when shooting raw with a Sandisk Extreme Pro card. So, one conclusion could be that the camera is ...

File deletion essentially means removing file entry from file system (file system contains information about all location and size of all files on disc or memory card). If something goes wrong file system may become corrupted, rendering card inaccessible (all the data may be still there, but without filesystem you can't tell where one file begins and another ...

For video I believe the requirements would be a card that can write 10 MB/s (mega bytes per second). This equals to 66x speed for a Compact Flash card. For shooting stills it's possible to get a longer burst with a faster card. If you want maximum burst length, get the quickest CF card you can afford. The math would be: 66 * 150kB/s = 9900kB/s ~ 10MB/s ...

The speed at which you can import the photos is governed by the card type and the cable you use to connect to your computer, so first make sure you have the fastest type of card available. Lexar make a Firewire 800 card reader which is stackable, so you can link two or more together as FW800 allows you to daisy chain devices in series. If you use a Mac you ...

Your first question should be How do you prevent blown out skies without underexposing other parts of the image? because you can always expose for the sky. It turns out the answer is the same for a compact or a DSLR because all cameras have a limited dynamic range. Yes, modern DSLRs have more dynamic range than your S90 but that only moves the point at ...

Why are not all images simply in DCIM? Slightly unhelpful answer: because that would violate the Design rule for Camera File System. Perhaps more helpfully, given that image files can have only 4 numbers in them (again due to the design rule), what would you expect to happen if you have more than 10000 images on one card - perhaps slightly unlikely for ...

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 ...

The UnDutchables firmware hack is based on a russian replacement firmware package which has been known to do weird things when formatting CF cards. I would suggest reformatting the card on your mac and not formatting it in camera again.


2

I'm not sure what an "Untouchables Firmware" is (my assumption is that it's some 3rd-party firmware) but it sounds as if the camera has somehow formatted the card into a format that only it can read. If it's happened with a second CF card, my suspicion is that there's a problem with the camera. Can you install a default/Canon firmware on the camera and see ...

Your entire existing infrastructure is geared towards SD cards, so why change? CF cards are generally more robust, which may or may not be a factor for you. Personally I find a 1 year life for that adapter extremely short, for me it would be enough reason to not get another one (but maybe there are other makes and models out there that are higher quality). ...

Don't forget, that the USB channel has bandwidth limitations. USB 2.0 spec High Speed is 480 Mbps (megabits per second). This means that an 8GB card can theoretically transfer in 134 seconds. Firewire 800, can do this in 80 seconds (Firewire 400 in 160 sec). Now, this is theoretical, because every USB or Firewire device connnected utilizes bandwidth. If ...

CF cards were used back then because they offered higher write speeds than smaller memory cards and some even offered then gigantic capacities by utilizing small hard drive inside. However, these days SD cards rival CF in speed and capacities are already beyond practical. For example, 8GB Class 10 SDHC cards I use in my SDLR hold around 700 raw images per ...

Since neither Windows nor the camera can read the card, I think the most likely scenario is that the changes Windows were about to write to the card were interrupted halfway through. Such interruptions will corrupt a file system for sure, and could happen if you just unplug the card instead of going through the Windows "safely remove hardware and eject ...

Opening files from a card on Windows should not corrupt it, since that action is only doing a read, and not altering the contents. You should never format, or delete images on anything other than the camera, primarily because of the various disk formats and implementation of them on computers. Most cameras use the Windows format known as FAT32. This ...

My question is, can a card get corrupted by using Windows to delete files from it and how can I try to recover the pictures on it? Yes, a card can get corrupt just by inserting it into a card reader, not only by deleting files. I had a multi-card reader and only the xD slot would corrupt the card. I could view them but once it was taken out it was no ...

I don't know how you could tell the age of the card, but I think it is more important to know roughly how many shots it has recorded, to format it regularly, (the formatting will remove wilting parts of the card), and, depending how often you use it, throwing it away after an amount of time that suits you, ie. a year maybe. Then mark the new one with the ...

Compact Flash theoretically has a limit of 128GB or greater. The S1 seems to be 6 megapixels, so on a 4GB card you could hold 600+ images If this is the S1 Pro, then according to this link: Compatible Media (As of July 2000 ): Microdrive: IBM: 340MB; Compact Flash cards: Sandisk: SDCFB-16t32140/48/64/9a1128| | Lexer Media: 4x type 8 MB to 80 MB 8x ...

I happened to notice this from the FAQ I referenced in the answer to your last question: Question: If I purchase a high performance CompactFlash card for my E-10/20N, will it reduce the time writing to the media. Answer: No, the writing time is controlled by the camera, not by the Media. In other words, it won't help. (This mentions the "N" ...

The E20 FAQ from Olympus says that CompactFlash-interface microdrives up to "1gig" are supported. That doesn't necessarily mean that bigger cards won't work, though — unlike SmartMedia, CF doesn't require device support for larger capacities, since there's a standard interface with "smarts" in the card itself. ("Smartmedia" is an Orwellian misnomer; it's the ...
