Best Sony SD Memory Cards

Two different types of memory cards can be used in the Sony A58. Sony PRO Duo, PRO-HG Duo, and XC-HG Duo will work with in addition to SD, SDHC, and SDXC cards.

Only only one memory card can be in the slot at a time. You will need to pick between an SD or PRO Duo card.

PRO Duo memory cards are a proprietary card format that is owned by Sony. For that reason, SD memory cards are quite a bit cheaper and can offer greater performance than PRO Duo cards.

In a hurry? My unbiased recommendation is to get this SD card to use with the A58:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

Performance to price ratio is excellent. Fast enough to use in a camera upgrade.

Best SD Cards

SanDisk, Lexar, and PNY are brands that make the best Memory cards. The best SD cards I have owned have been the SanDisk Extreme Pro memory cards.

That does not mean you need to purchase a card from SanDisk for your Sony ILCE-A58. Make sure the name sounds impressive. That will make sure you get fast read/write rates, water resistance, and other features.

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

The issues I have experienced with SD cards has been when I have used inexpensive generic brands. A low-cost card increases the possibility of card failure or corrupted data.

If you are looking to spend less money, don't buy a cheap card. You will avoid problems by purchasing a name brand card with a smaller storage capacity.

SDXC, SDHC, and SD cards can be used in the Sony A58. Use an SD card to get the best performance out of the A58.

The brand new SDUC memory cards are not supported by the A58.

Currently, there are four specifications of Secure Digital (SD) cards. New card specs add more features that allows for more memory capacity and faster read/write speeds.

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

SD Card Speed

Speed ratings of an SD card is determined by the sequential write and read speeds. SD memory card speed is essential for clearing the buffer for continuous shooting and recording video.

Slows memory cards can cut down the number of continuous photos the Sony A58 can capture. This is because the camera's buffer will not be able to write data to the SD card fast enough.

When shooting video, a slow SD card can cause an abrupt end to the recording. The video file may also be corrupted. If you are going to record video, it is important the SD card you use meets the requirements of the camera.

Read speed is important for file transfers to a computer. If you are filling up cards with images or video, a memory card with a fast read speed will cut down on the transfer time.

Speed Class Rating

Example of where to find SD Card Speed Class
10 inside of a C showing that the SD card is Class 10.

An SD memory card is assigned a Class rating based on the continuous write speed of the memory card. Class 10 is the best rating, even though SD memory cards can be purchased that have an improved write speed.

Here you can see all of the Class ratings and their corresponding lowest transfer rates:

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

Nearly every SD card worth choosing for the Sony A58 will be a Class 10 SD card. In the time period since the release of the camera, SD memory cards have gotten so much faster.

Ultra High Speed (UHS)

Example of where to find SD Card Speed Class
10 inside of a C showing that the SD card is Class 10.

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

There are 3 separate specifications. They are UHS-I, UHS-II, and UHS-III.

You can determine the rating of a card by looking at the front of the card. If the SD card has UHS, a Roman numeral I, II, or III can be found on the memory card label.

  • 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 A58 PRO Duo Card Compatibility

The Sony A58 is able to use a single PRO Duo or PRO-HG Duo memory cards. What PRO-HG signifies is that the memory card has a minimum read speed of 50mb/s and a 15mb/s minimum write speed.

You'll have to pay twice as much to purchase a Sony PRO Duo card than an equal SD memory card. Considering the price difference, I will not recommend purchasing a PRO Duo memory card for use in an A58.
