What lens should I bring today? (Dimensional Field of View Calculator by focal length)

I want to take landscape/scenery photos from afar today. I want to travel light and do not bring all the glasses with me but just when I open up my cabinet door, I paused. No, nothing is missing in the cabinet. I do not have idea on what to take.

Imagine that you have a ultra-wide lens (say 16mm in Full-frame equivalent) and a few telephoto primes like 200mm, 300mm and 400mm. Which one to pick? Yes, you can pick one ultra-wide with you but just which telephoto prime suitable for you today?

For example, you have decided that you are going to take the picture of Penang’s famous Kek Lok Si temple complex. You have picked a high-rise building not far away for the shot.

1. Estimate on how far you will be from the subject. You may make good use of Google Map or Wikimapia.

2. Then, you will need to pick a lens based on the distance from the subject with the suitable coverage range. You may use the calculator below.

By citing the sample case above, we are 1200m away from the subject and we would like to try using 200mm lens. Thus, just fill in 200 in the “focal length” column and “1200″ in the “distance from subject” column. Assuming that we are using a full-frame camera, so, we just leave the “crop factor” column with the value 1.

Field Of view Calculator

Crop factor (Full-frame = 1.0):

Focal length (in mm) (Eg. 200):

Distance from subject (in meter) (Eg. 1200):

Result:

Field of view (Horizontal) :

Field of view (Vertical) :

Field of view (Diagonal) :

3. By using the calculation above, we can find out on just how close we can get to our desired subjects.

Again by referring to our sample case above, we know that we can cover 216 meters horizontally which is in our case here, it is more than enough if we were to take a shot of the whole temple complex!
