Table of Contents
The Sony A450 uses SD memory cards, with a maximum capacity of 32GB.
It was released in 2010, and much larger and faster cards have been released.
The A450 will show an error if a 64GB or larger card is used. The camera will not be able to format the card.
Sony PRO Duo and PRO-HG Duo Memory Stick cards can be used, but they have been discontinued.
SD cards are faster, cheaper, and have larger storage capacities. The only reason to use a PRO Duo card is if you already have one.
If you need a lens, I have a guide going over fun affordable Sony A450 lenses.
Sony A450 SD Card Compatibility
The Sony A450 is compatible with the SD and SDHC standards.
Make sure the camera is using the latest firmware.
The newest SDXC and SDUC cards will not work with the A450. They are too large and will cause an error.
- SD (Secure Digital) - 128MB to 2GB.
- SDHC (Secure Digital High Capacity) - 4GB to 32GB.
- SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
- SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.
Image Capacity
Here’s the approximate image capacity for high-quality JPEGs from the 14.2 megapixel sensor:
- 4GB - 1,020
- 8GB - 2,040
- 16GB - 4,080
- 32GB - 8,160
Card Speed Class
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
Recommended SD Cards
Any 32GB SD card with UHS-I will be fast enough.
32GB cards will be the best value per GB. They’re also the only cards with UHS-I, which is helpful for use in other devices.
Don’t pay for a super fast card. The A450 can’t write data that fast.
Don’t buy a UHS-II card. The A450 doesn’t have the hardware to take advantage of the extra speed.
Don’t buy a used card. There is no way to find out how much life is left.

Sony A450 PRO Duo Memory Stick Compatibility
The Sony A450 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. They will cost 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.
Ultra High Speed (UHS)
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
