## What is Fallowfield?

As photographers and videographers, we're always taking crop factor into account. The problem is, we're always comparing our focal lengths and fields of view to what they would look like on a full-frame camera. What if you don't have a full-frame camera or what if you've never shot on a full-frame camera to have any idea what those lenses would look like?

Well Fallowfield allows you to pick your point of comparison. Fallowfield is an app that allows you to calculate field of view between any 2 cameras.

Let's say you're considering buying a new camera with a new lens. Maybe you want to pick up a Blackmagic Pocket Cinema Camera with a 20mm lens and you currently own a Canon Rebel. Well with Fallowfield, you'll be able to easily figure out what a 20mm lens on a BMPCC will look like on a Canon Rebel.

Of course, you can always pick a full-frame camera as well if you're curious how that will look.

Don’t see your camera in the list? No problem! Fallowfield lets you enter custom crop factors. If you don’t know your crop factor, you can also enter your sensor dimensions. 

With a growing list of cameras and internet-search-based crop factors, we hope that our community of users will submit any errors or omissions.

Enjoy this simple little app that helps you get a real-world sense of crop-factors.

### 2/5 — Calculation reversed?

*2017-06-23*

Hi there.  On a first look, the calculation seems to be reversed.  For example, in the screenshot posted, a 58mm lens on a 5DMkIV (crop factor 1.0) should look like a 58*1.67 = 96.86mm lens on a BMPCC with an effective crop factor of 1.67?  Or am I reading this incorrectly?
