Best Sony SD Memory Cards

The Sony A68 can use 2 different types of memory cards. Sony XC-HG Duo, PRO-HG Duo, and PRO Duo will work with and in addition SDXC, SDHC, and SD memory cards.

The A68 only has just one memory card slot. You'll need to pick between a PRO Duo or SD card.

PRO Duo memory cards are a proprietary memory format that is controlled by Sony. As a result, SD memory cards are lower priced and frequently provide considerably better performance than PRO Duo cards.

In a hurry? My advice is to get this SD card to use in the A68:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

Performance to price ratio is superb. Fast enough to use in a future camera.

Best SD Cards

SanDisk, Lexar, and PNY are brands that produce high-quality Memory cards. The best SD cards I have used have been SanDisk Extreme Pro SD cards.

That does not mean you need to purchase a card made by SanDisk for your Sony ILCE-A68. Look for cards with impressive-sounding names. That will make sure you get fast transfer speeds, shock resistance, and more features.

I have not run into errors with PNY Elite Performance or Lexar Professional cards.

When I have encountered problems with memory cards has been when I have used inexpensive generic brands. Not having a brand name increases the possibility of data corruption or card errors.

If you are looking to spend less money, don't buy a cheap card. You will be better off purchasing a high-quality memory card with a reduced capacity.

SD, SDHC, and SDXC memory cards can be used by the Sony A68. For the best performance, use a card.

The brand new SDUC cards cannot be used with the A68.

Currently, there are four types of Secure Digital (SD) cards. Newer card specs add features that provide for increased memory capacity as well as increased transfer speeds.

  • Secure Digital (SD) - 128MB to 2GB.
  • Secure Digital High Capacity (SDHC) - 4GB to 32GB.
  • Secure Digital eXtended Capacity (SDXC) - 64GB to 2TB.

SD Card Speed

The speed rating of an SD memory card is based on the sequential read and write speeds. The transfer speed of a card is important for video as well as continuous shooting.

A slow memory card can cause a decrease in the number of continuous frames the Sony A68 can take. This is because the camera's buffer will not be able to write to the card quickly enough.

When recording video, a slow SD card can cause an unexpected end to the recording. The video file could also be corrupted. If you are going to record video, it is essential the memory card you use meets the required continuous write speed for video.

Card read speed is nice to have for file transfers to a computer or laptop. If you are filling up cards with images or video, an SD card with a fast read speed will save you time.

Speed Class Rating

A memory card is assigned a Class rating based on the sustained write speed of the card. Class 10 is the top rating, even though SD cards are manufactured that are a good amount faster.

Here you can see all of the Classes and their corresponding lowest read/write speeds:

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Any memory card worth ordering for the Sony A68 will be a Class 10 memory card. In the time period since the camera was introduced, SD memory cards have gotten much faster.

Ultra High Speed (UHS)

The Ultra High Speed (UHS) bus can be found in SDHC, SDXC, and SDUC cards. The UHS bus cards to have increased write speeds.

Three separate specifications exist. They are UHS-I, UHS-II, and UHS-III.

You can figure out the UHS rating of an SD card by examining the front of the card. If there is a roman numeral I, II, or III on the label, that is going to be the UHS rating of the memory card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s

Sony A68 PRO Duo Card Compatibility

The Sony A68 may use one PRO Duo or PRO-HG Duo memory cards. PRO-HG signifies the memory card may have read speeds up to 50MB/s and a 15MB/s minimum write speed.

PRO Duo memory cards are usually double the cost of an SD card. Considering the price difference, I will not recommend purchasing a Sony PRO Duo memory card for use in a A68.
