Summary: Bought this for my Canon point and shoot camera which takes SD cards. Have also used it on a Nikon DSLR camera on occassion. It came formatted so I just put it in the camera and started taking pictures. Transfering the images and video off the camera was quick and easy. Higly recommend this memory card.
Summary: This card will not function in a Pentax K-01, and according to reports from Pentax users on Pentax Forums, several other models also have problems. Correspondence with Pentax has yet to provide a solution. In the meantime, avoid purchasing this card for your Pentax camera.
