CIPA, the Camera and Imaging Products Association, which tracks global camera and lens sales by major manufacturers, has released their report for June 2019, and it shows another significant drop in sales as compared to past years.
More specifically, the report shows that as compared to June of last year, camera and lens sales are down across the board by large amounts, with DSLRs dropping by 37% (in shipped units) and mirrorless cameras by 14%. Correspondingly, lens sales are down across the board as well. It is not particularly surprising news, as camera sales have been dropping for many years, and we have seen the point and shoot all but rendered extinct by smartphones, which are surely also cutting into the sales of some more advanced cameras, as many more casual shooters have opted for simply using their smartphones in situations where they might have purchased a lower-end DSLR a decade ago. While the lower sales certainly don't help the industry, I personally don't think they signal the death knell. I think it's likely that we'll eventually bottom out at a steady baseline, as advanced enthusiasts and professionals will always need more capable equipment.
