All lenses of the same focal length, regardless of what format they were designed to cover, “see” the world in the same way, but the size of their image circles can vary. For film, resolution is the term used to describe how much detail can be resolved usually measured in line pairs (lines per mm or lines per inch). For instance a 50mm lens on a Full Frame camera will give you a field of view of about 46°, but on the smaller sensor of an APS-C camera, the same 50mm lens will give you a 31° field of view, showing you less of the world. However, it more than likely will not cover larger sensors like the ones in Full Frame cameras, and even larger sensors like the one in the ARRI Alexa 65. This effect could be interesting for specific styles and scenes, but for most shooting situations, such extremely shallow depth of field could be distracting, and your focus puller would probably quit after the first shoot day. Physics is one of the big reasons why we will likely never see a lens set like that. The sensor size of mobile camera phones is variable in size but a 1/2.55″ sensor (used by the iPhone 11) is on the larger end of the spectrum.. 1-inch camera sensors are the next size up and are used in most compact cameras. The Creative and Technical Differences between Full Frame and S-35. The factor is still 1.5x. In the images below it’s easy to observe this lens’ complete image circle. Shooting on a camera with a Super-35 sized sensor like a Canon C300, Sony FS7, or an ARRI Alexa Classic with a 50mm prime lens gives us a specific field of view. Since the Ursa Mini Pro performs better at lower ISOs, you decide that you need lenses that can open up to T2 at least, but T1.4 would be even better. The DP would likely end up stopping the lens down to T4 or T5.6 anyway, and all the extra aperture and glass would go to waste.

Sensor size is the physical size (area, not number of pixels) of a camera’s image sensor, usually measured in mm width x height. Camera Sensor Size and Types Comparison. If digital, what camera and sensor size? However for a run-and-gun documentary, shooting on a smaller format like Super-16, or a comparable digital format like shooting 2K “center crop” on a Sony F55, shooting 2K on a RED Epic Dragon, or using a Blackmagic Pocket Cinema Camera, can result in a smaller, lighter camera, smaller lenses, typically faster lenses that need less light, cheaper rentals and possibly even a smaller crew, needing less set-up time. [VMI Note:  Celere FF primes and Sigma FF primes are consistently T1.5 throughout their 18-85mm range]. In that scenario, they needed to track down lenses designed to cover Full Frame or larger sensors, and there are more lens options than ever to cover these big sensors. At 12.80 x 9.60mm, they are also large enough to capture a decent amount of light. The iPhone 7 Plus’s main camera includes 1/3-inch sensor, which is slightly smaller than the 1/2.5-inch sensor (7.1 x 5.7 mm) found in the Samsung Galaxy S7. Considering sensor size is another way to assess the quality of your equipment. Make sure you understand the different types of cameras and types of lenses and how those factors combine with your camera's sensor size. A particular lens will give different fields of view if it’s used with cameras with differing sensor size. What’s the style of the project? It’s not that simple. If a lens was designed for Super-35 and APS-C (which are very close in size), it will successfully cover the sensors of Super-35, APS-C as well as smaller sensors like Micro Four Thirds and Super-16. This can be measured in horizontal x vertical. For ROGUE ONE: A STAR WARS STORY, shooting on Alexa 65 with big, heavy, vintage Panavision Ultra 70 anamorphic prime lenses was a great recipe for achieving epic, large-format images perfect for the big screen. For example photographers and videographers accustomed to the field of view they see when looking through a 50mm lens mounted on a Full Frame Nikon D810 (“FX” format in Nikon speak) might wonder what equivalent focal length will give them the same field of view on a Nikon D500 which has a smaller “DX” format sensor (which is similar in size to APS-C and Super-35 sized sensors). Sensor size is the physical size (area, not number of pixels) of a camera’s image sensor, usually measured in mm width x height. Necessary cookies are absolutely essential for the website to function properly. This article is written mainly for those who want to know the very simple concepts which allow camera operators to manipulate the Depth of Field in order to make them look more cinematic. We simply crop the circular image into rectangular shapes with various aspect ratios. All these formats need lenses, and the lens market is bigger and more confusing than ever. If you placed your camera and 16mm fisheye lens in a small square room, standing close to one wall, in the center of that wall, your camera would see the wall across from you as well as the walls to your left and to your right. / Cinematography, Article reproduced with kind permission from the online rental marketplace ShareGrid. The next time you go camera shopping, remember that the sensor size is a major feature. The cost to design and manufacture such a lens would make the resulting lens so expensive, no buyer outside of NASA could afford to own it. In the examples below, you can see how three 25mm lenses designed for different formats, shot on a camera with a Super-16mm sized sensor, at the same T-stop will produce images that have the same field of view, the same magnification, and the same depth of field. The individual glass elements would be enormous and would be difficult to match the tolerances achievable with smaller format high-speed lenses. For example, a 50mm lens on a Full Frame camera has a horizontal field of view of 46°. There are also a lot of companies rehousing lenses, giving filmmakers the opportunity to use lenses that were not originally designed for motion picture use. To create that same frame, or more accurately stated, a frame with the same field of view on an Alexa 65, you would need to use a 90mm lens (of course it has to be a 90mm lens that was designed to cover the Alexa 65’s sensor). When shooting on Super-35, to get a shot with the same field of view and depth of field, you’d need a lens that was roughly 13.5mm and T1.8. To add to the confusion it has become popular to measure a lens’ coverage (image circle) in “Ks.” To say a lens “covers” 4K, 6K, 8K, is flawed. If you look at the comparisons below, you can see how there is no relationship at all between “Ks” (pixel count) and sensor size. With the release of more high-end video cameras with larger sensors like the ARRI Alexa LF, Panavision DXL2, RED MONSTRO, and the Sony Venice and more recently with the Sony FX-9, Canon C500 II, Sony A7S Mk III & Panasonic S1H we have more choices than ever when it comes to formats and lens options. and has a maximum aperture of f1.7…wow. There is a formula to figure it out. The increasing number of sensor sizes and lens options, has made things more complicated than ever especially with all the lens adapters available and cameras with interchangeable lens mounts. For instance in order for a lens to cover the entire sensor of a Full Frame camera like a Canon 5D or the Sony Venice, it would need an image circle with a diameter of 43mm. As exaggerated as the above example is, it’s a good demonstration of why we benefit from having different sensor sizes and film formats. Therefore a camera with a Full Frame sensor shot at T2.8 has the equivalent depth of field as a Super-35 sensor at T1.4. I say “roughly” since a common “4K” resolution is actually 3840 x 2160 pixels, and there are multiple pixel counts that are accepted as “4K.” In still photography digital cameras, pixel count is often measured in “megapixels.” One megapixel = 1 million pixels. To find right the lens, you divide 50mm by 1.5, which gives you about 33mm. The Canon 5D Mark IV is 30.4 megapixels, which is about 30,400,000 pixels, which is 6720 x 4480 pixels, and in theory could also be called 6.7K. Then you could buy one set of primes that you could use on every job! The size of the woman’s face, the geometry of the room, and the depth of field are the same with all three 50mm lenses. For smaller, compact cameras they're given in fractions of an inch (1/N inch format). Courtesy of However, more than ever we need to make sure to consider all the variables before deciding which format is best for a given project. Photography and Camera News, Reviews, and Inspiration.

When we blew it up to … Since Ks are a measure of pixel count not the physical size of an image sensor, using Ks in this way is problematic.
