I just wanted to tell even my little personal test here, I have today carried out immediately upon receipt of the goods.
I put the card in my Canon EOS 550D and tested following:
- HD and Full HD recording: Easily in maximum resolution and maximum recording time. Camera has never indicated that the memory threatens to overflow. When you play the test video is no single stuttering found. Perfect!
- JPEG images: 18MP in Continuous Shooting at ISO 100 and simply draufgehalten only finger. Camera has photos by geballert in maximum speed and the map has co-written it without delay. At 100th photo at a time I stopped.
- RAW images: Here the camera is running in the first 7 shots at full speed, then is throttled to half speed. Do not know, obs is located on the map or on the internal image processing.
Conclusion: For Full HD is no class needs long 6 card. These Class 4 card is with their speed recommended far above the average and for the Canon EOS 550D in all areas without exception!
