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

Last Updated on May-11-2010 one Commented

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.

Estimate on how far you will be from the subject

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!

By calculation, we will know how close we can get to our subject.

Now, you know what you going to get even before you step outside of your house!

Enjoy photo shooting folks! Thanks for visiting our website!

Canon EF-S 18-55mm f3.5-5.6 ISIn response to demands of photographers, this standard zoom lens is designed with Canon’s Optical Image Stabilizer technology while retaining the compactness and lightness of previous models. Its stabilization allows sharp hand-held shots at shutter speeds up to four stops slower than otherwise possible. It consists of 11 elements in 9 groups and uses an Aspherical lens element to correct aberration for excellent image quality throughout the zoom range and a circular aperture for exquisite rendering of out-of-focus backgrounds. Without a lot of size, weight or cost, this lens expands picture-taking possibilities any time slow shutter speeds are needed.
