I use the memory card in a Canon EOS 600D. Fit on the 16GB card at full resolution (18MP in RAW and JPG) ca. 550 Photos (+/- 30). The card is fast enough to record HD videos (the 600D may 1080 / 30p or 720 / 60p record) or RAW shooting to store (approx 3,6Bilder / sec). I use the card for several months now and Estimation of some 3000 images are gone over it. So far I had no problems. Considering this the price, the map is a real recommendation!
