Best Sony NEX-7 Memory Card

Two different kinds of memory cards are compatible with the Sony NEX-7. SDXC, SDHC, and SD cards are compatible plus Sony PRO Duo and PRO-HG Duo memory.

There is only room for a single memory card to be in the camera at a time. You will have to make a decision between an SD or PRO Duo memory card.

Sony is the sole owner of the PRO Duo card format. Because of this, SD cards are more cost-effective and generally will have considerably better performance than PRO Duo cards.

Pressed for time? My advice is to get this SD memory card to use with the NEX-7:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

64GB or larger cards are not compatible with the camera.

Best SD Cards

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

You do not need to buy a card made by SanDisk for your Sony NEX-7. Just make sure the name sounds impressive. That will mean you get faster read/write rates, shock resistance, and more features.

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

When I have had problems with SD cards has been when inexpensive no-name brands were used. Not having a brand name increases the chance of data corruption or card errors.

If you would like to save money, don't buy a cheap card. You will avoid problems by purchasing a professional-quality memory card with a reduced storage capacity.

Sony NEX-7 SD Card Compatibility

SDXC, SDHC, and SD cards can be used in the Sony NEX-7. Use a memory card to get the optimal performance from the camera.

The newest SDUC memory cards cannot be used in the NEX-7.

Currently, there are 4 types of SD (Secure Digital) cards. More recent memory card specs add tech that provides for greater storage space as well as increased data transfer rates.

  • 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

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

A slow card can cause a reduction in the number of continuous frames the Sony NEX-7 can take. This is because the buffer in the camera is not able to write to the SD card fast enough.

With video, a slow card can cause recording to stop. The video file could also be corrupted. If you intend to capture video, it is crucial the SD 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 have cards that are full, a memory card with a fast read speed will cut down on the amount of time it takes the transfer to finish.

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.

The Sony NEX-7 requires no less than a Class 4 SD card.

The sustained write speed is what establishes the Class rating for an SD memory card. Class 10 is the highest rating which is given to cards with a write speed of more than 10MB/s.

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

Every brand name SD card that you can get online will have a Class 10 rating. To determine the class rating of an SD card, look for a number inside of a C on the label.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
This card has a UHS-I rating. UHS-II and UHS-III cards will have II or III, respectively.

The Ultra High Speed (UHS) bus is available in SDUC, SDXC, and SDHC cards. The UHS bus allows offers a way to increase data transfer rates.

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

You can find out the rating of a card by examining the label. A Roman numeral I, II, or III on the front of the card, that is the UHS rating of the SD 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 NEX-7 PRO Duo Card Compatibility

The Sony NEX-7 is able to use either a PRO-HG Duo or PRO 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 need to hand over more to purchase a Sony PRO Duo card than a comparable SD memory card. Considering the price difference, I will not recommend purchasing a Sony PRO Duo card for use in a NEX-7.

Image Capacity

  • 32GB - 9,280 images
