for what a toothpick?
The largest Memory Stick card you can use in your Sony Cybershot DSC P71 is 256MB http://www.mymemory.co.uk/compatible-memory/Digital_Cameras/Sony/Sony_Cybershot_DSC_P71
Most Canons use SD cards. There could be variations, though, especially if it is an older camera.
It uses the standard sony memory card that can be found anywhere basically.
Page 21 of the owners manual indicates the 4GB is the larges stick that the camera can use. However I believe it is talking about the CF memory stick not the Sony memory stick. I purchased a 4G Sony memory stick and the camera refused to recognize it. I do have a 2G Sony stick in the camera that works just fine. I also have a 2G CF stick that has no problem with the camera.
Honestly the only difference between different brand cards is the size they come in. What evr slot the Sony camrea comes with you can use any card with. The best sized memory card though would have to a either 2GB or more. you can store thousands of pictures on a 2GB card.
Yes, you need to use a memory card reader
The option will be in the camera settings :)
No. Sorry. Maybe if you mode it.
Most Sony consumer grade cameras use Memory Sticks. Some use both those and SD cards. SanDisk manufactures both. However, you must make sure you have the right type.
It will use memory cards from any playstation.
The SONY PSP doesn't necessarily need a Memory Card to function. And by function i mean to play a game or use the Internet but up to now SONY PSP's are sold with no internal memory which means if you want to have Pictures, Videos, Music, and save game data you need to have a memory card. So basically you need the memory card if you want to use the PSP to its intended use.
Most mini-B (Mini USB cables will work, but you can normally get a replacement for any digital camera at any electronics or camera store. The other option is to use the Memory Stick and a memory card reader to view/download the images. In fact, it's recommended that you don't hook up and download directly from the camera anyway, but from the Memory Stick itself from a card reader.
