Best selling doesn't make it the best. Canon has sold boatloads of its various EOS and Rebel cameras. Good cameras? Yes. Best cameras? Maybe, but probably not, especially with their entry level cameras.
I believe that Kodak sold even more Instamatic 104s. Using the logic that the best selling cameras are the best one leads to the conclusion the Instamatic 104 was the best camera ever made.
Warning!! Handling a Hasselblad can be harmful to your financial well being!

I leave the digital work for the urologists and proctologists.
