The world of photography is currently going through some growing pains. Camera sales are down 25% from a few years ago. Several camera companies have gone out of business while others are struggling (though they won't admit it). What's the cause? Why is this happening?
Enter the smartphone! Why should you buy a point-and-shoot camera when you can use your smartphone? With each new generation, the photo capabilities of these phone cameras just gets better and better. And that's not to mention all the cool apps that are available for photo editing. It's hard to say "no." Unfortunately, point-and-shoot camera sales have been the bread-and-butter for these companies.
As for professional cameras, don't plan on them going away any time soon. These cameras offer more features, better sensors, and perform better in low light situations (to name a few) - and they cost more money. That said, the traditional DSLR market is going through another change of it's own. And that's called mirrorless cameras. Traditional DSLRs use the same basic design as the old 35mm film cameras of yesteryear. While mirrorless technology eliminates the mirror and allows for a host of new features including cheaper manufacturing costs. While not perfect, mirrorless cameras offer many more advantages than DSLRs. And most people agree it's the wave of the future.
It will be interesting to see how this all plays out. But at the end of the day, it's about the photograph and not the camera!
