While we have a Canon PowerShot A75 (fm woman) and a PowerShot A95 (on the go), but I use this card for the Canon EOS 350D, which is with its 8 million pixels suitable for such a large map. They are 256 pictures in, but this is only an estimate because the images of the EOS vary in size greatly, and can sometimes be more than 5 MB in size. I do not mean raw, but the finest resolution in JPG. Otherwise I use 512er and 256er have a lot of time where everything was very expensive. I prefer to use only when the small cameras. Well, I do not notice much of a difference to the 512ern and 256er cards in speed. They are fast in the computer. The speed at which the camera is barely measurable for me, because the camera anyway can take pictures very quickly one after the other and this card seems to have no problem. I am very happy with it and have ordered a second today. What is also important, they can be pushed well and remove. I've had times 2 cards from another brand the jammed something. Recently I noticed soeine because of Kranftanstrengung on the stone floor - but survived. That can not happen with this card, it can be moved without muscle power. Emotionally, I am very happy with it.
