The only possible cause would be having changed the aspect ratio the camera is recording in... IDK if the camera has viewfinder masking when the different ratios are used, but it would affect the images either way. But I don't think that what you mean by "zoomed in" is the field of view we are all thinking it is. I believe that what you probably mean is ...

The only possible way to "zoom" with a prime lens is to change to a camera with a different sensor size, or to crop the image in-camera. The latter is generally feasible only with mirrorless cameras because DSLRs have a fixed angle of view viewfinder whereas mirrorless cameras have an electronic viewfinder. You can of course crop the image as you wish on a ...

Do I have weird eyes or a misconception about normal focal length? You have a misconception about what "normal focal length" is. But don't feel bad. Your misconception has been oft repeated by many others who claim to be authorities on the subject. They mix up two different concepts: perspective and apparent magnification. Perspective A normal lens is one ...

The original phrase was "normal angle". The earliest reference related to photography that I could find dates to 1909. Earlier references are mostly related to medicine. One photographic reference to a "normal lens" in 1893 was referring to an unmodified lens. When the focal length is equal to the diagonal of the frame, the angle of view (of the diagonal) ...

First: The rule-of-thumb: “Human perspective is achieved when the focal length about matches the diagonal measure of the format”. This lash-up yields a diagonal angle of view of about 53⁰. A still camera, such as a 35mm with an aspect ratio of 1:1.5, will deliver a 45⁰ horizontal angle of view. Such a lash-up is labeled “normal”. Historically, focal length ...

According to this the iPhone SE has an 29mm-equivalent lens, so on a Fuji with a 23.6x15.6 sensor (Fuji XT-3)(crop factor 1.53) you need a 29/1.53=19mm lens for the same field of view.

Bad photos (no focus). What are these photos called? I am highly qualified to pontificate on this subject.( not that i always feel the need to be qualified on a subject in order to pontificate on it. ) I have made many many of these photos over the years. I call them "mistakes". Sometimes these mistakes even cause me to question if i should even own a ...

IMO, a neural net would be overkill for identifying blurred images. Just run an edge detection filter on it. If there are no strong edges anywhere in the frame, then it's blurred.

I would search for "out of focus photography" or "blurred photo". In digital image processing software "unsharp masking (USM)" is used as an image sharpening technique. Maybe you'll find some useful images under this term too. Have a nice day.
