I am looking for a prime lens to pick up, and I'm wondering if there is any difference between 35mm and 50mm in terms of the end product if I just stand back more with the 50mm. I use the Sony a6000 ...

I know that when I want to calculate Depth of Field by hand one of the variable elements in that equation is the Circle of Confusion. In layman's terms, what is the "Circle of Confusion," how do I ...

I have often wondered if the focus of a lens at a particular focal length is an exact point or a range within a few millimeters. This becomes all the more important when manually focussing. How far ...

I'm facing often the same kind of trouble when taking landscape pictures... I end up with a picture that could be great but that is totally not sharp ! Example : I set up the maximal focal distance ...

I guess the title and the picture explain my question well.

I know that aperture changes the depth of field (DOF), but why is it that by making the image appear larger (by getting closer to the camera or zooming in) there is less DOF?

In the book Digital Photography Complete Course, there is a page that discusses and illustrates depth of field: There is an info box that says the following: The point at which you focus the lens ...

All mirrorless cameras have the image in the rear LCD and the electronic viewfinder (EVF) fully generated by a computer, making many utilities such as noise removal, text overlays, histograms, etc ...

I just hope to learn the relationship between depth of field (DOF) with the distance on my mobile phone. When I capture one cup with the distance about 20cm from my phone, what 's the DOF? When I ...

I'm using panohelp.com to prepare tables with hyperfocal distances for my camera. The most important camera-specific info I have to plug in is the circle of confusion (0.019mm for my Canon EOS600D). ...

If the camera format is 35mm, the focal length of the lens is 35mm, the aperture is f/4, the subject distance is 25ft, and the hyperfocal distance is 39'7", then what would be the range of focus when ...

There's a lot of information here and elsewhere about how things such as aperture, focal length, and subject/focus distance affect Depth of Field (DoF). Most people seem to understand that side of it ...

Let's assume I have a prime lens for full frame, with fixed specs (let's say 85mm f/1.8). Changing the lens is not an option, but I have a choice of a full frame camera and a crop sensor camera. The ...
