When digital became a reality, it also took plenty time to displace film. When I bought my first digital camera (a Canon D30), it had many drawbacks compared to the top-of-the-line 35mm film cameras of the time. A measly 3 MP resolution, a confusing crop factor (b/c the sensor wasn't truly 35mm), not great battery life, limited low-light performance. Yet it was clear digital was the future. Sony and Fuji are making great strides, but Canon and Nikon have had decades to perfect their systems. And while mirrorless manufacturers are investing very heavily, Canon and Nikon have really only been putting out fairly iterative updates (especially Canon).
