This makes a lot of sense, because the framing is mainly to get a certain amount of a person's face or body.

When shooting 2.35:1 I would definitely want wider lenses than for 4x3 or 16x9. It's all about how I want to frame the people vertically. The wider aspect simply gives more peripheral view.
What's worth noting is that shots captured on Super 35, which are composed for different release formats, are cropped vertically and horizontally to achieve the desired final aspect ratios. In other words, a 2.35:1 theatrical print will actually have less vertical information than the 1.33:1 "full screen" home video master.

Pixar doesn't do any cropping for their "full screen" home video releases. They actually rearrange the elements within every shot so that the same information is conveyed as in the widescreen version.

Having seen both the IMAX and regular versions of Avatar, I can say that the regular 2.35:1 version is definitely cropped vertically from the IMAX. And in my opinion, the IMAX aspect ratio is the better presentation of the movie, because the 2.35:1 felt a bit too tight in many shots.

That exactly what i mean. The image area of 35mm film is 22mm * 16mm - twice the height is 32 mm.

That is the modern definition (not my definition) and this definition is for beginners more useful than the old.



After the old definition the standart lense for T2i will be around 50mm.

Beginner will think 50mm is the normal lens for filming - cool, for wide images i need a good 24mm lens.

But in reality a 24mm lens on a T2i will not archiv a wide image.

I grew up with this stuff. But I teach and I know there are people reading this who are confused. The holes in 35mm film run along the top and bottom in an old fashioned SLR. In a movie camera they run on the left and right side. So the width of the image is defined by the width of the film in movies and the height is defined by the film in an SLR. So a 35MM SLR Still image is a whole lot bigger than a 35MM movie image. Hope this helps and not hurts the newbies that the T2i will bring in.

The DoF of the 7D or T2i is very near the DoF of 35mm movie image.
Why should this "hurts the newbies that the T2i will bring in"?

Lenses for T2i / 550D

Hi guys,

Just noticed that you are talking about which lenses are working with the new Canon Rebel T2i / 550D.

I wrote a review / shot a video ("February") with a pre-production 550D earlier this week that you might have seen and read.

I've just started a new series on my blog talking about essential accessories for this camera, especially considering if you're on a budget. I started out with lenses:
On a budget? Pimp your new Canon EOS Rebel T2i / 550D with essential accessories! Part 1: BASIC LENSES | Nino Film - Blog - Nino Leitner

Looking forward to feedback! Please write me if you feel I missed a lens that is a "must-have"! Thanks!
