Skills of using Canon EOS 7D

Canon 7D continuous shooting is fast, but its durability is not as good as Canon 1D series. Because an average of 6MB JPG or an average of 2 1MB RAW+JPG will be written at a speed of 8 pages per second, the writing speed of the CF card used should be around 90MB/S. When tested with the CF card of Sandisk 16GB 90mB/s,

Canon 7D's high sense is a weakness. ISO should not exceed 640, and the quality of ISO is relatively good between 250 and 640. If you play too much, you will find that the image quality of Canon 7D is not ideal. If the ISO of 1800W pixel is slightly lower, the resolution will be very high.

Canon 7D viewfinder is very high-end and suitable for viewfinder viewing. The focusing speed is very fast.

The suitable lenses for Canon 7D are: 24- 105/4, 17-40/4,15-85,50/1.2, 70-200/2.8 IS and/kloc-0.

Canon 7D feels heavy and the shutter is tough. Buy 7D for speed and 5D II for image quality.
