There has been discussion from the experienced cinematographers that recommend planning lenses for a camera based on the angle of view (in degrees) or field of view desired. The AbelCiné FOV calculator was as I recall a good way to compare the field of view of different lenses' focal lengths but, unless my memory has failed me, there has been a change and now it only compares some large sensors including the BMCC and some tiny sensors. The sensor size as well for S16 seems incorrect. And no mention of micro four thirds at all! Nearly useless for us. To find an alternative, look at this information which I have also posted in another forum"
"I found an iPhone App, called Angle of View, which does a great job in comparing angles of view for up to five sensors. The beauty is you can enter your own custom sensors and compare to predefined common formats. I also created custom formats for full frame and Super 35 by using a common 16:9 aspect ratio to normalize all comparisons to the HD aspect ratios used by the BMD cameras. So that takes a bit of work as well as $1.99 to Apple, but I am very happy with the results.
I display results for FF, S35, BMPC4K, BMCC, and BMPCC on the same screen as buttons. Clicking any of those five buttons shows the comparison to all others. Also shows crop factor comparisons in relation to the button clicked so you can quickly see the crop factors related to S35 or FF or MFT as you prefer. As you all know (I think) the AOV for a normal 50mm lens on a full frame sensor is 39.6 degrees. You can easily then adjust sliders or drop downs to find out how to get that or any desired angle on the BMPCC for example. Of course you know the answer to that is a 17mm lens. But I find it helpful since so many experienced cinematographers are saying you need to pay attention to the angle of view and not the crop factor.
Is my thinking correct on this or have I missed some salient point? Thanks for any reply."
