Table of Contents
The Nikon D50 uses SD memory cards. The largest card that can be used is 2GB.
An error will occur if a card 4GB or larger is used.
MultiMediaCards (MMC) can also be used. However, they have been discontinued for a long time. I would not recommend buying one.
My Nikon D50 Lens Recommendations
Nikon D50 SD Card Compatibility
The Nikon D50 is compatible with the SD memory card standard.
SDHC, SDXC, and SDUC are newer standards that are not compatible.
- 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.
SD Card Image Capacity
Estimated number of large JPEGs:
- 512MB - 240 images
- 1GB - 480 images
- 2GB - 960 images
Memory Card Speed
The speed rating for SD cards is established by sequential read and write speeds. The speed of the memory card is important in the event that many photos need to be written to the memory card.
SD Card Speed Class Rating

The Class speed rating of an SD memory card is based on the sustained write speed of the SD card. A Class speed rating of 2 means that the card can maintain a write speed of at minimum 2MB per second.
- Class 2 - 2MB/s
- Class 4 - 4MB/s
- Class 6 - 6MB/s
- Class 8 - 8MB/s
- Class 10 - 10MB/s
Nikon D50 Memory Card Full Error

Attempting to use a SD memory card that is 4GB or larger in size in the D50 will result in the digital camera to display an error message.
Use a memory card that has a storage capacity of 2GB or less to fix the problem.
If you have a SD memory card that has a storage capacity less than 2GB, and the card is not working, try to format the memory card in the camera.
Recommended SD Memory Cards
Any new card will be fast enough. It isn’t possible to buy better performance.
Don’t over pay for a fancy label.

MultiMediaCards (MMC)
MMC cards are the predecessor of SD cards. They have similar physical dimensions to SD cards.
The maximum size available is 128MB.
If you have one, it can likely be used in an SD card reader.
I would not recommend buying on used. They will cost more than a 2GB SD card.
