Wide-Angle Photo Tips: Size matters!

In your daily photo practice, a slight difference in focal length can have a huge impact on your images. Does it adjust everything in the photo? Do I get that entire steeple on the image without having to go so far back and then shooting in the sun? How exactly does a fisheye lens work? Read on and find out the answer.

Wide-angle lenses, those with particularly short focal length, have a number of advantages compared to telephoto lenses. They are smaller thus easier to handle and capture more of the subject because of a larger acceptance angle. For this however, you have to get closer as you are not granted the magnifying effect of a telephoto lens.

The shooting angle applicable with wide-angle lenses or as you can say the field of view of your camera. purely and solely depends on two factors:

  1. Focal length
  2. Film format

In principle, the angle increases with decreasing focal length and increasing size of the negative. This is mathematically expressed this way:

α = √(a^2 + b^2) * 100° / 2f*

a and b correspond to the side length of the negative, f is the focal length. So you can choose which camera is easier for your next Lomo walk, I already did the math and made this table for some cameras:

Thus, you can easily estimate what camera can get you your desired angle because even without a protractor at least 90° and 45°, this can easily be determined with your hands.

I hope the list will help you with camera options and brings light into the darkness of the angle calculation. I look forward to your likes and comments! Now go out and take pictures!
