Originally posted by wissink How do you figure that a DSLR has bettere IQ over a mirrorless camera? Often times they use the same or similar sensor. The differences being view finders, brand names, and most importantly the photographer's ability to use the thing.
What you say about the photographer being a key factor is true.
Yet the fact that mirrorless cameras run their sensors continuously means they run hotter and a hot sensor is a noisier sensor (

The EVF vs. OVF debate is a long-running one. I've used both and can see the advantages of both. An OVF avoids the lag, granularity, and contrast problems of EVFs but an EVF provides much better feedback on how the image will look under the chosen exposure conditions (no more chimping!). It's a personal decision and I can see how some photographers would get better results with each viewfinder design (and worse results with each viewfinder design.)
