I dont have any experience with 35mm film cameras. I own Canon 5D MII full frame camera. I wonder what full frame camera lens would be equivalent to Hitchcock's favorite 50mm movie camera lens. If I am right, it would be something around 70-80mm on full frame sensor. I am a bit confused, because Hitchcock used the 50mm lens because it mimicks normal human vision. But if its equavalent on a full frame camera is around 70-80mm, it doesnt mimick human vision at all. Its more like a portrait lens. Spielberg's favorite lens is 21mm. Lets say I want to mimick this focal length on my full frame Canon 5D camera. What lens should i use?

This artile says that all of the Imax release prints were made from the orignal negative? https://theasc.com/articles/dunkirk-wrangling-two-large-formats I dont get it. How they edited the movie? They cut the original negative?

So the sensor has the same size, resolution and aspect ratio? Why use IMAX lenses?

New Avengers movies are shot with this camera. I wonder what is the sensor size. Does anybody know how is it different from the Arri 65mm camera? Maybe the aspect ratio is different?

Thare's a lot of grain too in few scenes, but i think it was good for the movie.

I just saw Dunkirk in IMAX (great experience) and I noticed how many shots where sometimes slightly out of focus when the actors was moving too quickly. Was this intentional or is it too hard to keep quickly moving subjects in focus with IMAX cameras? I think it actually helped the movie to look less staged.

I just saw the movie. The image was very blurry. Did they use some softening filters? It was very distracting.

These kind of lamps are most common... http://markkoh.me/wp-content/uploads/2015/03/vlcsnap-2015-03-08-15h34m24s174.png

Another thing I see in todays movies are "thousands" of table lamps (usually witch lampshades) in interiors which are all switched on (even when the main light is on and sometimes even in full daylight). Their purpose is only decorative and it looks really weird. Have you noticed it? :) Nobody in real life has six table lamps switched on in every room. :)

If you compare older movies and new movies, you notice that the cinematography these days is increasingly more flawless. Perfect lighting, perfect camera movement, perfect focus, perfect color grading, movies are relying too much on CGI... I watched some cinematographers at work and they fine-tune every detail (even though ordinary viewer cant notice these details, even unconsciously). It seems there is no excuse for faults these days. Everything has to be too perfect and computerized, the environments become too sterile and clean... On the other hand when you watch older movies you notice the lighting is not overly perfect, you notice clumsy camera movements, sometimes actors go out of focus, there was no color grading, no digital polishing... There was something more life-like about it. What do you think?
