Smartphone Autofocus vs EOS M1, M3 & M5, Canon T2I
3

I have a regular iPhone 7, not the 7 Plus with the dual cameras . Its about 3 years old I guess. In the last year or so it has become my most used camera. For a bunch of reasons:

-Its always there and in my pocket.

-Its super convenient - I can post pictures instantly, share them with my family, whatever instantly.

-If I want to do post processing, its super convenient.

-It shoots very fast even under adverse conditions.

Today while I was at home I decided to do some tests and compare it directly to my collection of EOS M's (1,3,5) and my T2I DSLR.

I took a section of my home office that I know my EOS M's always have trouble focusing - a plain almond colored file cabinet with low contrast to use as a test. Where the drawers are there is lots of horizontal lines because of the drawer openings. I also decided to shoot the vertical sides.

The M1,3,5 would not focus in the middle of the cabinet regardless of light. The T2I would focus if the light was bright but would hesitate a bit if it was dim. The iPhone would focus no matter how dim or bright it was.

Than I decided to do the edge of the cabinet. The M1 and 3 would focus but would hesitate. The M5 was much better, but the T2I being faster than all of them. The iPhone again would focus quickly no matter what.

So that raises an interesting question - if the iPhone can focus even in tough conditions - why cant the EOS M's.

If the camera companies are going to survive they are going to have to offer the same if not better performance than the smartphones.
