Hello, Mr. Deakins and all the Cinematographers over this fantastic forum. I hope you Mr. Deakins and Mrs. James are well.
I would like to ask you (Mr. Deakins, Mr. Mullen but also who wants to join the topic), if it is possible, your thoughts about the focal length paired with the sensor size.
I know (if I remember correctly) that you had shot ‘Empire of light’ with an Alexa LF as well as for ‘1917’.
if I remember correctly for ‘1917’ you choose a 40mm lens that resulted in the field of view something near a 35mm-lens of a 35mm full-frame sensor in order to have a similar feeling to some still photographs that you researched as inspiration for the movie.
This kind of “calculation” is something that you did also on ‘Empire of light’?
Let’s say that you had to shoot an OTS and for that kind of OTS you were going to shoot with a 32mm (on a super 35 sensor/stock) but now with an LF sensor your 32mm is something like 24mm (roughly) field of view (but not for the perspective distortion). In this case, do you maintain the 32mm focal length moving forward the camera to have the “right” composition, or do you use another lens (probably a 40mm)
Furthermore, even the depth of field is differently related to sensor size.
To be short, did you think about the sensor size when you had to choose the lenses during the shooting in order to have your desired field of view (same thing for the T-stop and depth of field)?
I own a super35 sensor camera with a high crop factor (something like 1.56) so sometimes when I have to shoot something wide I have to use a really wide lens like 16mm in order to have a field of view something like 24mm.
I won’t deny that sometimes it confuses me because it doesn’t let me choose the goal in a totally free way.
Sorry if my English is not good enough and the post could result in confusion. Thank you in advance for your time and your availability.
I wish you a peaceful day.
