That really depends on the camera being used.Originally Posted by blazing fire
For landscapes its the same old thing as it was in film days. In landscapes you want detail which meant in film days you used the larger format negatives to capture the detail in the scene. The same thing goes for digital. If you want to capture the detail in the scene then you need a large format sensor.
Hasselbad and the other large format camera's have moved over to digital backs and they capture a lot more detail than the Canon 5D with a 35mm sensor which will capture more detail than the Canon 50D with the APC sensor.
As for quality of the sensor's - Personally I believe that Digital is now as good or better than film.
