The iPhone 4 is actually the most-popular camera of all on Flickr now, but the iPhone 4S has yet to crack the top 5 list of most-used cameras on Flickr, which features traditional cameras like the Nikon D90 and the Canon EOS 5D Mark II in second and third place. But give it a few more months and we fully expect the iPhone 4S to start gaining a lot of ground, mostly because the 8-megapixel shooter on the iPhone 4S is one of the best cameras ever seen on a smartphone.
On the cameraphone-specific list, the iPhone 4S has now beaten out the iPhone 3G, iPhone 3GS, and HTC EVO 4G. The iPhone 4S camera is set apart from its predecessors with an 8-megapixel sensor that captures pictures up to 3264-by-2448-pixels in size, a new IR filter and a redesigned lens. Thanks to new hardware and updated software, Apple claims photos on the 4S have better white balance and greater dynamic range that improves color accuracy than what could be offered with the iPhone 4.
The chart below shows how quickly the iPhone 4S has been adopted by cameraphone users on Flickr.
