Best Sony CF Memory Cards

The biggest CF Card that is compatible with the Sony A700 is 32GB. There could be compatiblity issues if you use a larger card.

The size limit comes from the use of the FAT32 file system. The A700 cannot format a card to bigger than 32GB.

If you are in a hurry, my recommended CF card is:

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.

Card Reader

The UGREEN 4-in-1 card reader is what I use with my CF cards.

The UGREEN card reader uses USB 3.0. Transfer speeds over USB 3.0 will be much faster than the Sony A700.

The reader also supports these memory card types:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards
  • 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.
