Sometime in the past few days, the iPhone 4 became the most popularly used camera on Flickr – two months after TechCrunch noted that it was poised to take the top spot. The Nikon D90 now holds the second spot, although its share of users has remained constant whilst the iPhone 4 has surged to the front. The next three spots are taken up by various Canon EOS line cameras including the 5D Mark II, Digital Rebel XSi and Rebel T1i.
In terms of smartphones the iPhone 4 took the lead a long time ago but it continues to extend its lead. It is followed by the iPhone 3G, 3GS and then the HTC Evo 4G. Surprisingly the iPod Touch rounds out the top smartphone cameras at number 5.
The iPhone 4 becoming the most popular camera in the Flickr community comes after the iPhone 3G held the top spot for just over a year. It lost the top spot earlier this year as it saw a significant reduction in users as the iPhone 4 surged in popularity (just see the above graph and the drop-off in 3G users).
