Don't Overpay for A Sony A58 Memory Card

The Sony A58 uses SD memory cards and supports capacities up to 2TB. Since its release in 2013, SD technology has advanced dramatically—modern cards are faster, more reliable, and offer exceptional value.

Bottom line: Any UHS-I SD card works great. A 128GB card gives you excellent storage without overspending.

Your camera also accepts Sony PRO Duo memory cards, but they’re discontinued and typically more expensive. SD cards outperform them in speed, cost, and capacity—stick with SD unless you already own a PRO Duo card.

Sony A58 SD Card Compatibility

The Sony A58 is compatible with the SD, SDHC, and SDXC standards. Each of those standards use a different file system.

Check to make sure the camera has the latest firmware.

The newest SDUC (Secure Digital Ultra Capacity) cards will not work with the A58. They are too large.

• SD (Secure Digital) - 128MB to 2GB. (FAT12/16)
• SDHC (Secure Digital High Capacity) - 4GB to 32GB. (FAT32)
• SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB. (exFAT)
• SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB. (exFAT)

How Many Photos Can You Store?

Here’s the approximate image capacity for high-quality JPEGs from the 20.1 megapixel sensor:

• 32GB - 5,400
• 64GB - 10,800
• 128GB - 21,600
• 256GB - 43,200
• 256GB - 86,400

Understanding SD Card Speed Ratings

Class rating is determined by sustained write speed. The rating will be shown as a number inside of a C on the label.

For example, as card that could write data at 5MB/s would get a Class 4 rating.

Class 10 card are likely much faster than 10MB/s. That’s why there are additional ratings for high resolution video.

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

Choosing the Right SD Card: What to Know

All modern SD cards will handle photos and video on your A58. However, smart shopping matters:

Avoid these common mistakes:

• Don’t overpay for ultra-fast cards. Your camera has write speed limits—premium cards won’t improve performance
• Skip UHS-II cards. This camera lacks the hardware to use them, so you’re throwing money away
• Never buy used. There’s no way to verify remaining lifespan or detect hidden wear

Should You Use Sony PRO Duo Cards?

Sony A58 PRO Duo Memory Stick Compatibility

The Sony A58 can use PRO Duo and PRO-HG Duo Memory Sticks. Those are a proprietary memory card format that Sony has discontinued.

PRO-HG are the fastest with read speeds up to 50MB/s and a 15MB/s minimum write speed. The largest capacity available is 64GB. Expect to pay at least twice as much as an SD card.

If you have a Memory Stick, go ahead and use it.

I would not recommend purchasing a PRO Duo card. SD cards are easier to find, less expensive, come in larger capacities, and are compatible with more devices.

What Is UHS Speed? (And Does Your Camera Need It?)

The Ultra High Speed bus (UHS) is available with SDHC, SDXC, and SDUC memory cards.

There are three different specifications that increase with maximum transfer rates.

UHS ratings are shown on a card label as a Roman number I, II, or III. Product listing will prominently display the rating.

• 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
