You might also want to take a look at my other post Professional photographer based in the Yukon, Canada, and founder of Shutter Muse. If you want to calculate the equivalent focal length for a Micro Four-Thirds camera, you would divide the focal length by 2. I’m a bit confused. The crop factor for that sensor is 1.5 x. Here’s the info page: Your email address will not be published or shared. This factor determines the equivalent field of view of a lens when used on a camera with a sensor that is either smaller or larger than our reference full frame sensor.Many people are familiar with the two common APS-C crop factors: 1.6x for Canon, and 1.5x for Nikon, Sony and everyone else. The crop factor of a RED HELIUM® sensor is similar to the RED DRAGON® sensor at 6K FF. Throughout this book and Stunning Digital Photography, I list focal lengths in 35mm equivalent. Simply input your focal length, sensor size, and max aperture and we'll give you what the 35mm equivalent is of that configuration. For our example, we’ll simply work with a Canon APS-C sensor which has the dimensions 22.2 x 14.8 mm.The reason that we want to know the crop factor of a camera is to understand what kind of field of view we will get with a particular focal length. The term crop factor refers to the ratio of a specific sensor to a 35mm full frame sensor. ️ Share it: My mm f/ lens, on a. sensor, is equivalent to a 157.5 mm f/ 2.1 lens. Therefore, if you want to calculate the equivalent focal length for a compact DSLR, you would divide the 35mm focal length by 1.6 for Canon or 1.5 for Nikon. mmCalc is a super simple photography focal length calculator. Manufacturers often provide the horizontal and vertical dimensions of a sensor, so we can use Pythagorean theory to calculate the diagonal dimension. Use this tool to preview how a given focal length will appear depending on resolution setting and sensor type. A higher crop factor means a given lens will appear as if it were a longer focal length, and at the same subject magnification, that lens will also have more depth of field.

When looking for lenses for Super 35 cameras I'm seeing the Equivalent FOV stats listed with a roughly 1.5 crop factor.... this is where I get confused since the way I understood that the Super 35 lens is targeting the smaller sensor in order retain the 50mm FOV? At 4.5K resolution, the DRAGON crop factor approaches Super 35 mm Film (3-perf). Then, as the resolution is decreased from the maximum setting, the crop factor increases. The important thing to know is that the crop factor is the ratio of the diagonal dimension of the sensor. If you want to calculate the equivalent focal length for a me… c2 = a2 + b2 therefore c = √(a2 + b2) Full frame sensor dimensions: 36mm x 24mm therefore diagonal dimension is √(362 + 242) = 43.27mm Sigh he had the gall to say I was wrong the BMPCC 4K’s crop factor was 2.0, which I was able to verify with the above calculations.Thank you for this article. At 4.5K resolution, the DRAGON crop factor approaches Super 35 mm Film (3-perf). Then, as the resolution is decreased from the maximum setting, the crop factor increases. If the simple calculator doesn't suit your needs, we also offer calculators for crop factor based on sensor size and completely custom lens + sensor crop factor calculations. Dan is also the President of the First Light Image Festival.fantastic for curious people who wants to know facts.The Think Tank free gifts with an order of 50$ or more is it available for a customer with a shipping address in Canada ?Unfortunately I don’t think they ship internationally from their website.Thank you, I was able to use this to correct someone who was wrongfully claiming the BMPCC 4K is 1.9x crop (they were dividing sensor width by height. But how do we get to this number, and how do you calculate the crop factor for other sensor sizes?The important thing to know is that the crop factor is the ratio of the diagonal dimension of the sensor. All rights reserved. Illustration depicts viewable area relative to a traditional 35 mm stills photography sensor by default, but other reference sensors are selectable within the drop-down menu.The relative size difference between two sensors is typically expressed as a "crop factor."

This means that you could use a lens that covered that focal length, perhaps a 24-70mm zoom, and set it to about 32mm to replicate the field of view of a normal 50mm lens if you were using an APS-C camera instead of a full frame camera.Below you can find some of the most common crop factors for modern digital sensors, but using this simple math technique that I have explained above, you can now calculate the crop factor of any sensor that you come across. For example, placing a 50mm lens on an APS-C camera will actually give us a field of view that is equivalent to that of a much longer lens on a full frame camera. Could you help me understand? "Equivalent Focal Length" refers to the equivalent focal length that would mimic the angle of view of the current resolution setting if it were used on the chosen reference sensor.For a background on this topic, also see our articles on Video Aspect Ratiosand Anamorphic Lenses. Crop Factor Calculator Get the full-frame (35mm) equivalent focal length and aperture for different sensor sizes. I see two different versions of 4/3 conversions. On their website, they say that their sensor size is 18.96mm x 10mm (Four Thirds).
