I find that last line perfectly justified.

OP’s post was incredibly dismissive and incorrect but was written as if it was from an expert.

It’s textbook misinformation as far as I am concerned.

Numerical aperture alone does not tell you anything about the amount of light gathered. The product of aperture and sensor size does. Phone cameras still have much smaller sensors than DSLRs. Your advice to learn more about photography certainly seems good.

The Hubble Space Telescope has an aperture of a pathetic f/24 [1]. I guess they should just fire an iPhone up there instead, huh.

The trick to getting the best out of camera phones is to shore up their weaknesses with external devices. Cell phone cameras are multiple stops slower than "real" cameras (i.e. they take in 1/4 to 1/8th as much light). So you add light to the scene to shore up that weakness. Most of these pictures were probably lit very carefully with high quality lights, or else were taken in bright daylight, and the phone was proba…

f-numbers do not have the same meaning across different sized sensors. For example, f/1.5 on the iPhone is equivalent to f/8.2 on a 35mm camera. This is pretty slow by the standards of full frame lenses, and as you can see in my other post, it is not expensive to acquire much better lenses than this that will achieve much better results with less effort.

See the chart on the first page of this article: https://www.dpreview.com/articles/6780391159/all-apple-iphon...

For a detailed explanation of how to compare f-numbers across cameras have a look at this article: https://photographylife.com/equivalence-also-includes-apertu...

You're telling people to do more research but don't understand how photography in general works.

The speed of the lens is not the main factor. A Micro4/3 lens at f/2 is cheaper than a full frame lens at f/2, which is cheaper than a medium format in turn. The iPhone's sensors are much smaller still than FF.

The lenses on the iPhone are equivalent to some of the cheapest lenses in any given system.

Indeed, a comparable system would be the 10-18mm EF-S plus whatever kit lens you have.

Talking about relative aperture and angle of view at the same time is incredibly misleading. If you want to talk about angle of view, you need to use absolute aperture.

It’s not really about being justified, it’s about being gentler with people. We don’t have to jump all over each other, there is another way.

I think OP will live.
