Overview: The Sony MS-MT-series Memory Stick PRO Duo Mark2 memory card lets you save your digital pictures and video clips from compatible Sony Alpha-series DSLRs, NEX-series interchangeable lens cameras, Cyber-shot digital still cameras, and Handycam digital camcorders. The Mark2 designation indicates the card is suitable for use for AVCHD format video recording, providing the appropriate minimum write speed.

Compatibility: This Memory Stick PRO Duo Mark2 memory card will work only with Memory Stick PRO Duo Mark2 and Memory Stick PRO Duo compatible devices. If the instruction manual included with your Memory Stick device does not mention Memory Stick PRO Duo Mark2 or Memory Stick PRO Duo compatibility, this memory card should not be used. It is also compatible with the MagicGate copyright protection system.

Capacity: The capacity of this Memory Stick PRO Duo Mark2 is 4 GB. Because a portion of the card capacity is used for system files, the actual usable capacity is approximately 3.66 GB. The approximate recording capability of this card is 590 high-resolution photos, 1 hour 30 minutes of Full HD video (LP Mode), or 15 minutes of Full HD video (PS Mode).

Note: Still Image recording capability based on using a Cyber-shot digital still camera in 18 MP setting. Video recording capability based on a Handycam digital camcorder in AVCHD LP (5 Mbps) and PS (28 Mbps) modes.

Transfer Speed: Memory Stick PRO Duo Mark2 can transfer data at much higher speeds compared to standard Memory Sticks. When used in Memory Stick PRO-HG compatible devices, this Memory Stick PRO Duo Mark2 has a minimum write speed of 32 MB/s, based on Sony internal testing.

MagicGate: This Memory Stick PRO Duo Mark2 employs MagicGate encryption technology in order to protect copyrights. It enables you to enjoy your own recordings as well as prevents unauthorized use.

Crutchfield asked  
Why did you buy this?

Recently purchased a video camera and we needed a memory card [ Modenah  May 23, 2018 ]
Couldn't find locally. [ Robert  Oct 19, 2016 ]
I needed some extra memory. Another site offering the same item had some negative comments about the item. Apparently, some sellers are offering fake items. Having dealt with Crutchfield in the past, I knew they wouldn't engage in such practices. [ Michael  May 03, 2016 ]
works with present adaptor and need the extra storage [ Jan  Mar 21, 2016 ]
