f8 Lens Toolkit

This app does exactly what it says it does, i.e. it’s an easy conversion tool that allows you to figure how what the equivalent focal lengths to get the same field of view between camera formats. It also shows you which corresponding focal length between camera formats if you’re working with varied aspect ratios. Simple to use and very useful. I’ve also got this developer’s Cadrage Director’s Viewfinder. I was awarded a redeem code, so I can’t review it directly, but it works very well too. E

Daunting to think of all the camera sensor lens options out there and that the developers scoured for all that and put it together in such a useful reference tool. It’s good for figuring out solutions but also inspires some ideas of possibilities to test instead of just default choices. One request : in the Sensor comparison, would love if the sensor modes for a camera could be cycled as a slider quickly instead of having to select from a list of modes. This may not be useful for others, but on

This is one of the most useful apps on my phone. It’s got a great database of cameras and lenses, but you can also create custom cameras/lenses if yours isn’t already there. I use this ALL the time to determine what lens I need for a given coverage at distance. But also whether I can get everything in the shot when space is limited. It’s really robust. My most frequently used features are FOV and DOF. Can’t recommend this highly enough.

Does exactly what I want.

The app is super helpful as a starting point to compare lenses and cameras to match each other. Once I have my lens choices, I will begin my tests.
