RESOLUTION & PIXEL COUNTįor 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 the remainder of this article this format will be referred to as “Full Frame.” In the chart below the red rectangles represent the relative physical size of many common cameras and formats. A Full Frame digital sensor like the ones found in a Canon 5D, Sony a7S I II or the Sony Venice, as well as traditional 35mm still photography film, all have areas that measure roughly 36x24mm. Sensor size is the physical size (area, not number of pixels) of a camera’s image sensor, usually measured in mm width x height. Also, not all lenses work with all formats, and not all formats are the right choice for every project. All these formats need lenses, and the lens market is bigger and more confusing than ever. Today with digital cameras, we have more formats than ever: 1/2”, 2/3″, Micro Four Thirds, Super-35, DX, APS-C, Full Frame, Vista Vision, etc. These are literally measurements of the physical size of film used to capture the images (in this article, I won’t dive into exactly how the film is measured and what direction it passes in front of the camera). Motion picture film formats are fairly straight forward: 8mm, 16mm, 35mm, 70mm. digital or film? If film, which format? If digital, what camera and sensor size? There is no single “best” format that is right for every project or situation. However it’s important to know the differences as well as what results should be expected before selecting your sensor size and lenses. 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. – “What will full frame lenses look like on a S-35 sensor.”Īrticle reproduced with kind permission from the online rental marketplace ShareGrid MORE FORMATS THAN EVER Evidence that full-frame equivalents matter (to some).This article aims to help questions such as: I have a hunch that I would get different results in APSc user groups… If 50% of the group is doing it, these users may consider the full-frame as a standard. Online pollĥ0% of the MFT users convert their numbers to FF-equivalents. I decided to take a poll to find out what other MFT users were doing. That is, if you’re even aware of the crops to begin with. The camera values and ff-equivalents would eliminate the need for calculations to understand equivalent lens and camera settings. I personally think that not only should one list the camera’s values, but also the ff-equivalents. Having a standard scale for these attributes is like having one photography language across different sensor types. If this is you, you’re likely also aware of the crop factor (not to mention the additional light) and likely think in full-frame equivalents. Or perhaps you’re using a speed booster like the Viltrox EF-M2 or the Metabones. Photographers that transition from MFT -> APSc -> Full-Frame, may care more about equivalents than those that are content with one sensor-size. To reiterate from the videos, there is a crop applied to non full-frame cameras to get to full-frame equivalents. Please take a few minutes to watch the following videos: The tables below list the equivalent values.Įquivalent Focal Lengths for different sensor types Full FrameĮquivalent F-stops for different sensor types Full FrameĮquivalent Isos for different sensor types Full Frame I’m calling for this to be continued with respect to not only focal lengths, but also aperture and iso values. About full-frameįor both film and photography, the 35mm Full-Frame sensor has been used as an industry standard. In order to do that, you should understand the relationship between the numbers and their camera sensors. Wow, how does anyone understand this stuff? The point here to understand is that various cameras produce nearly the same photo using different settings. I’ve listed the values here from the above photos:
