Sensors & Circles by Andy Shipsides (AbelCine)

At AbelCine, one of the most common questions our techs get these days is about lens coverage with different cameras. It’s no wonder that we get these inquiries, as there’s an endless stream of new cameras coming out, all of which have different sensor sizes and specs. We frequently get questions like this: "Does my 16mm lens cover the Blackmagic Cinema Camera sensor?" or "Does my lens cover 6K on the RED DRAGON camera?" These are both great questions, which we can generally answer with a simple yes or no. But they bring up some really interesting points that all modern cinematographers need to understand when choosing a lens, camera and recording format. So this column is all about lenses, image circles, sensor sizes and resolutions. The best place to start is with the lens "image circle" and exactly what that means.


When we talk about a lens, we often describe it by the film format or sensor size that it’s designed to work with. Super 35mm lenses are designed to work with Super 35mm film or sensors that are around the same size; Super 16mm lenses are designed to work with Super 16mm film or similar sensors, etc. This can be confusing in itself, as we talk about lens focal length in millimeters, as well. You can have a 35mm (focal length) Super 16mm lens, for instance, and a 16mm (focal length) Super 35mm lens.

When we describe a lens as being designed for Super35 or 16mm film, we’re actually talking about the image circle of a lens. Lenses are designed to project a circular image onto a sensor or film plane. The size of the projected image circle is based on the design of a lens. An average "Super 35mm" lens has an image circle diameter of around 32mm to 35mm, while an average "Super 16mm" lens has an image circle diameter of around 15mm to 18mm. Lenses designed for smaller formats, usually in video cameras, are often referred to in inches. A 2/3-inch-type lens has an image circle of around 11mm, and a 1/2-inch lens image circle is around 8mm.

In the graphic above, you see Super35, Super16, 2/3-inch and 1/2-inch image circles on top of each other. This photo was taken on a 50mm (focal length) lens. If it were a Super 35-type lens, we would get the outside image; if it were Super16, we would get the image outlined for that and so on. The focal length of the lens is exactly the same; we just get more of the image with the larger image circle. Focal length is unrelated to image circle, which is a big point of confusion for many of us. A 100mm lens has the same focal length, regardless of its lens type; the difference is just how big of an image circle it projects.

Sensor Overlays



So hopefully you understand the image circle concept. Now let’s discuss how it plays together with sensor (or film) size. Super 35mm film is standardized at 24.9×18.7mm (31.1 diagonal), but our modern digital sensors come in a variety of shapes and sizes. From the large full-frame 35mm sensors found in many DSLRs to the small 1/2.5-inch sensors found in many POV cameras, sensor sizes vary a lot. Below is a graphic with a variety of camera sensors overlaid in relative size. As you can see, each sensor is a bit different.

Zeiss CP.2 Under Sensor Overlays

We say a lens "covers" a sensor when its image circle produces an image over the full sensor size. So how do we determine if a lens’ image projection will "cover" a specific sensor? Just overlay the two. Look at the graphic of the image circle of a Zeiss CP.2 prime lens (right), which produces an image circle of 43mm (diagonally), completely covering every sensor size from full-frame 35mm down to 1/3-inch sensors.

From the diagram, you can see that a Zeiss CP.2 will work with a huge variety of sensors. But what about a Super 16mm lens with a 15mm image circle?

In the graphic below, the Super 16mm lens doesn’t cover anything larger than the "Super16"-sensor type. That makes sense, of course, but notice what happens to all the larger sensors; they vignette. This is exactly what you would see if you put a Super 16mm lens on a camera like the ARRI ALEXA or Sony F55, which both have sensors around the size of Super 35mm film.
Super 16mm Under Sensor Overlays



Okay, so lens coverage isn’t all that complicated when you compare sensor sizes to a lens image circle. But many modern cameras offer a variety of aspect ratios and resolution modes, which allow the camera to record different areas of its sensor. Cameras that have this option are effectively altering their sensor size. The RED DRAGON is a great example of a camera that has these modes.

In this graphic (below, right), I’ve overlaid a standard Super 35mm lens image circle over a DRAGON sensor. The lines over the sensor indicate different recording areas and aspect ratios. As you can see, the area outside the 6K image isn’t covered by the lens, but the inside areas are all covered just fine. So this lens doesn’t cover the 6K resolution area on the RED DRAGON.

This brings up another question: What does resolution have to do with lens coverage, anyway? The answer: Nothing. The 6K resolution area of the DRAGON is physically 30.7×15.8mm (34.5 diagonal) in dimension, meaning that each photosite on the sensor is around 4.9um (0.0049mm) in size. A different sensor type could have larger or smaller photosites in the same area, producing lower or higher resolutions.

The lines over the sensor indicate different recording areas and aspect ratios. The area outside the 6K image isn’t covered by a Super 35mm lens.



Let’s go back to our original questions: "Does my 16mm lens cover the Blackmagic Cinema Camera sensor?" and "Does my lens cover 6K on the RED DRAGON camera?" Super 16mm lenses don’t cover the Blackmagic Cinema Camera sensor, as the image circle of Super16 glass is 15mm, and the BMCC sensor has a diagonal area of 18.4mm. As for the RED DRAGON at 6K, the answer depends on the lens image circle. Having a 6K resolution has nothing to do with lens coverage, but it does describe a large area of the sensor. Lenses like the Zeiss CP.2 primes and CPZ.2 zooms are designed to cover the larger full-frame-sensor cameras, so we know they will work. Other Super 35mm lenses generally won’t cover that image area, but the only way to know for sure is to test them.

Lenses / Field of view

A 50mm is a 50mm is a 50mm, is often said to explain the differences in formats versus focal lenghts . But what does it mean?
Of course it says: Any focal length is just that length no matter what you do with it.
Why does a 50mm on a 16mm/2K camera looks closer on a 35mm/4K camera?
The answer is simple, you just use a smaller area of the image. Since the image projected on the film plane/sensor is the same for a given focal length, the smaller image area only uses the centre part of it. In order to get the same shot, you will have to step back or closer with the camera or use a wider / longer lens.

What is Anamorphic?

Contrary to popular belief "Anamorphic" is not a shooting aspect ratio, but a technique to record an image.
The traditional Anamorphic technique makes it possible to use the maximum of the film/sensor area when shooting a 1:2.35 frame. For this you need to crop (morph) the image x2 from the sides when you use a 4:3 / 1:1.33 image area.
This is academy format in 4-perf 35mm for example.
When using a 16:9 / 1:1.78 image area, it makes more sense to use the so-called 1.3 anamorphic lenses.
These lenses crop not x2, but x1.3 times.
Netto result is the same, you can use the maximum available image area and have a 1:2.35 frame in the end.
Since the end result is a 1:2.35 frame, people like to refer to this as "Anamorphic".
One of the trademarks of this technique is the depth of field, or better the lack of it.
Needless to say that the focuspuller will have a very hard time here.
To make the technique possible you will need longer lenses (2x) then when you would use with spheric (normal) lenses. This results in very little depth of field. A shooting T-stop of 5.6 is no luxury in this format.

Optical Axis

The optical axis has not much to do with the lens/camera very often. Only in case of static objects the lens/camera decides where the axis to a given object is. As soon as an object is moving that object often determines where the axis will go.
When shooting with actors, imagine that the talent in frame has a 3meter/10foot stick attached to their nose. Wherever the stick points is the optical axis.
I saw film students making tracks with the camera in order to get to the other side of the axis. Often a little change in staging, or even a different eye line does the trick.

Cooke zoom lenses history

 From the Cooke Optics website:

Cooke Varotal Zoom lens   1971

Lens designer Gordon H. Cook designed the 35mm Cooke 20-100mm, T3.1 Varotal zoom lens, released in 1971. It was the first high quality zoom designed for professional motion picture photography that incorporated a totally new design concept that has remained the basis for all Cooke zoom lenses subsequently produced. It was produced through the late 1980s.

The lens was made with a sealed front focus unit and fixed front element that eliminated the risk of dirt and moisture being drawn into the lens and allowed for easy fitting of matte boxes and filter holders onto the front. The lens was enhanced with anti-reflective wide-band Varomag high performance coatings. This advanced technology achieved new standards in shadowed area definition, light transmission and durability, in addition to giving ghost and flare-free characteristics.

Gordon H. Cook received the 1988 Academy of Motion Picture Arts and Sciences, Gordon E. Sawyer Award for this and other technological advancements during his career as an optical designer.
