Best Sony CF Memory Cards

The Sony A700 has an CompactFlash card slot that is compatible with cards with a maximum storage capacity of up to 32GB. Using larger capacity Compact Flash cards will cause the camera to display an error.

Maximum card size is limited because the Sony A700 uses the FAT32 file system.

New CF cards are substantially larger than what the Sony A700 is limited to. The important features to pay attention to are read and write speeds. A CF card with a faster read speed can save significant amounts of time waiting for photos to transfer.

Calculated time needed to transfer 32GB:

  • 160MB/s - 3 minutes 45 seconds
  • 120MB/s - 5 minutes
  • 50MB/s - 12 minutes

This is my recommendation for the best memory card for the Sony A700:

SanDisk Extreme 32GB CF Card

  • Read speeds up to 120MB/s.
  • Write speeds up to 85MB/s.
  • Water, x-ray, & shock proof.

Best CF Cards

The best value Compact Flash memory card is going to be either 16GB or 32GB. Smaller cards are going to cost more per GB.

A pro card does not add a noticeable amount to the cost. Having a high-speed card will remove the need to upgrade the card when you upgrade your camera.

Compact Flash Card Types

CF cards come in two different sizes. The cards are referred to as Type I or Type II.

The difference between the types is the thickness of the cards. The width and length of the cards are the same.

  • Type I - 3.3mm thick
  • Type II - 5mm thick

The Type II spec were thicker so Microdrives could be used in the Sony A700. A Microdrive was a little mechanical harddrive, the size of a compact flash card.

When CF cards were first launched they had high prices and very small capacities. Microdrives were the only solution to get large storage sizes.

Microdrives are no longer being made. Because they were mechanical, they often failed. So you cannot find them used.

Another usage of the Type II slot is for Compact Flash card adapters. There are adapters that will allow you to use Micro SD or SD cards in a Compact Flash slot.

Memory Card Reader

There's a bright blue LED that bothered me. It is now covered in gaff tape.

The UGreen 4-in-1 memory card reader is compatible with four common memory card formats. These include all memory cart formats camera manufacturers use in all but the latest professional-level cameras.

The UGREEN memory card reader connects over USB 3.0. The card reader's USB 3.0 transfer speeds will be faster transfer rates than what the Sony A700 can achieve using the USB transfer mode.

There are lots of positive customer reviews for the reader, which I agree with. I think it is a good product because the card reader has been compatible all the computers (Windows, Mac, and Linux) I have tried it with.

The cable stops card slots from interfering with other accessories or devices that are plugged into another USB or nearby port.

When I searched for a card reader that would be lighter for travel, I had to return a couple of orders. I encountered the most frequent problem in customer reviews, the memory card readers did not work with my computer.

The ugreen reader can be used with the following memory card formats:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards (UHS-I supported)
  • Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
  • MicroSD, Micro SDHC, & Micro SDXC Cards

Avoiding Card Read Errors

One of the most common problems with cameras that use CF memory cards are damaged card slot pins. If a pin is bent, you may see a 'unable to use card' error message.

To avoid damaging pins, do not force a Compact Flash card into the Sony A700. The extra space for a Type II card allows a Compact Flash memory card to be aligned incorrectly.

If the CF card won't effortlessly slide into the slot, remove it and check the alignment of the card. Also, check to see if these is any damage to the memory card.

If it looks fine, carefully align the compact flash card and try inserting it again.
