Can iphone4s photography compare with professional SLR scalpers? Can I go to professional photography level?

It's pure exaggeration. Indeed, the 4s camera is good, and it is not inferior to ordinary household DC without digital zoom. But compared with DSLR, not to mention the 5D2 level, even an ordinary entry-level SLR like Canon 500D can easily kill 4s. We can know from the price that a 4s sells for more than 4,000 yuan, and an entry-level SLR also sells for more than 4,000 yuan. 4s is so versatile that the camera is only a small part; SLR can only take pictures, and all the money is spent on images. If Apple doesn't get parts for free, how can it get better quality parts at a price ten times lower?

If you want to compare, go to Canon and Nikon official website, or find some full-pixel proofs of entry-level SLR in the evaluation, look at that resolution, and then compare with ip4s, and you will know where the gap is.

As for the professional level, it is still far from it. But because of convenience, ip has become the most used photo tool on flickr.
