I have just viewed holiday pictures of 2 aquaintances; one of them used a Canon 550D with kit lens and an iphone 7.

About 40% of the pictures taken with the 550D were not sharp, visibly not sharp viewed on a 16 inch screen, terrible at 100%. This is not a focus problem, because nothing was sharp. And it is probably not a problem of hand shake, because the pictures were taken in broad daylight at around 1/1000s; also the phone produced better results in many cases.

Any explanations? Peter

Can’t tell for sure without more info (or better yet some samples w/ EXIF). Can they forward some?

The 550D, like all DSLRs, is capable of fabulous results, even the the kit lens. Without seeing any samples or without more details, the usual explanations would be:

  • probable user error, including technique and inappropriate image settings, and/or
  • unrealistic expectations, especially with respect to depth of field. Phone cameras use tiny lenses and sensors which give near infinite depth of field = everything near to far is going to appear in focus. The larger sensor and physically longer lenses for the DSLR will give much narrower depth of field = sharp focus will only be at/near the focused distance and objects nearer or farther will not be sharp.

IMHO, YMMV
