Card Capacity

• Since there are no new Nikon D50 cameras sold anymore, owning an old one or buying a second-hand unit means staying within the limitations of the SD card's capacity. Apart from 1 and 2GB SD cards, it can also use lower-capacity SD cards including 256 and 512MB cards. Apart from the 12MB of internal memory, this camera has an official maximum capacity of 2GB. This is the largest SD card available during the time that the camera was still in the market.
  
  

SD Card Manufacturers

• Nikon provides a list of recommended cards to use in its cameras. For the D50, this includes SanDisk, Toshiba and Panasonic. According to Nikon, experts at the company extensively test various cards to guarantee performances in Nikon cameras. As the company doesn't recommend other card brands for the D50, it reminds users that they can use these cards at their own risk. As an old DSLR camera, the D50 is only meant for use with the SDSC card family. This is the first generation of SD card officially released in the market and it offers a maximum capacity of 4GB.
  
  

Card Compatibility

• Nikon specifically states that the D50 can only accommodate up to a 2GB SD card. However, some users find they can use the 4GB card with their D50s (see Resources). Although not guaranteed, use only SDSC and not SDHC (High-Capacity) cards.
  
  

SD Card Formatting

• Some 4GB SDSC cards that work with the D50 should be formatted in a computer using a FAT32 file system. This is slightly different from the standard FAT16 file system used in standard D50 cards. Yet, the wisest way to handle the 2GB limit is to simply buy multiple 2GB cards recommended by Nikon. This way, the user can utilize more disk space without risking possible file corruption.
