In the calculator, just introduce your camera type (sensor size), aperture, focus distance, focal length (the real one! not the equivalent in 35mm) and teleconverter to calculate the depth of field: Hyperfocal distance: The closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp mmCalc is a super simple photography focal length calculator. Simply input your focal length, sensor size, and max aperture and we'll give you what the 35mm equivalent is of that configuration. 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

mmCal

My calculator here uses the diagonal of the frame to compute the equivalent focal lengths. The calibrated focal length is ~153mm and the film size is 9×9 inches. Since your frame is larger than a 35mm frame, you should expect the 35mm equivelent focal length to be much shorter than the 153 mm specified Photography light calculator The combination of shutter speed, aperture and film speed/ISO (and light modifiers) are expressed as E V or Exposure Value. This number depends on the amount of light present in a scene, either natural light (sun/moon) or artificial (strobe/lamp) EVS = EV100 + log2(S / 100) where S = desired ISO. I wrote this tool to plan long exposures outside my camera's typical range. Get more background on exposure and camera settings from Fred Parker . Useful wikipedia articles: Exposure Value. Shutter Speed. F-Number (Aperture) Sunny f/16 rule This calculator computes the equivalent lens focal length and aperture necessary to produce the same angular field of view and depth of field on two cameras with different sensor sizes. For example, a DSLR camera like the Canon T4i, Canon 60D or Canon 7D (with their sensor sizes of 22.3 x 14.9mm) mmCalc is a super simple photography focal.

The calculator default numbers represent full bright direct sunlight. The way the exposure is said is 1/2000 second at f/11 (EV 18) at ISO 800 (is EV 15 100 ). An equivalent is also 1/125 second at f/16 (EV 15) at ISO 100 (is EV 15 100 ), or other Equivalents of course, like 1/250 at f/11 at ISO 100 (also is EV 15 100 ) The calculator will automatically adjust for any focal length multiplier or field of view crop for the selected camera. Focal is simply a fancy term that means the distance setting at any aperture that produces the greatest depth of field In the calculator, just introduce your camera type (sensor size), aperture, focus distance, focal length (the real one! not the equivalent in 35mm) and teleconverter to calculate the depth of field: Hyperfocal distance: The closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. When the lens is.

• Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated. It is also possible to add up to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds. The app also includes a timer.
• This calculator computes the equivalent lens focal length and aperture necessary to produce the same angular field of view and depth of field on two cameras with different sensor sizes. For example, a DSLR camera like the Canon T4i, Canon 60D or Canon 7D (with their sensor sizes of 22.3 x 14.9mm) can be compared to a compact camera like the.
• This calculator will tell you the focal length and/or aperture you have effectively accomplished when stitching multiple photos together. The calculation can be used for any camera format and will give results with numbers relevant to that format (not converted to 35mm equivalent)
• Crop Factor Calculator Get the full-frame (35mm) equivalent focal length and aperture for different sensor sizes. Just enter the focal length and maximum aperture of your lens and then choose a sensor size
• EV Calculator. Half stops are marked with *½ Just saying EV 16 has no meaning (other than to describe shutter and aperture equivalent settings). We instead might say EV 16 at ISO 200, which then defines a useful exposure setting, probably for full direct sunlight in that case
• es the effective aperture A e for a given frequency f or wavelength, λ and antenna gain G.. Example: Calculate the effective antenna aperture of the Russian RT-70 radio telescope in Crimea (Russia): its antenna gain is 69.5 dBi or 9000000, working frequency 5.0 GHz (or wavelength 6 cm)

Equivalent Aperture = (F-Number) x (Crop Factor) Equivalent ISO = (ISO) x (Crop Factor^2) You need to apply all three in order to get an equivalent photo. Don't misinterpret that I'm saying ISO 200 on M4/3 is the same as ISO 800 on full frame. It's not. Hopefully this goes without saying, but any side-by-side test will show ISO 800. Found this site to see what my MFT lenses widest aperture is in terms of a FF camera and wanted to know if this seemed accurate.. For example my lumix g 12-35mm f/2.8 according to this calculation is only a 5.6 in full frame equivalent. 5.6 on a full frame camera isn't great at creating a shallow depth of field, however, on my lumix g 2.8 I feel like the depth of field is decent, better than. 35mm Equivalent Focal Length Calculator. If you'd just like to get a lens' 35mm equivalent focal length, just use this handy calculator. Crop Factor and Aperture. Crop factor does not affect the aperture of a lens. This is because like focal length, aperture is a physical measurement that does not change Both images were shot at 100mm f/2.8. The APS-C image has an equivalent aperture about 1 stop smaller, i.e. f/4. If you look at the number 1 near the front of the ruler and the number 3 near the back, you can see they are slightly more in focus in the APS-C image thanks to this smaller equivalent aperture

Now go to Equivalent Exposure and choose your desired settings for aperture and ISO. Exposure Calculator calculates the correct shutter speed value. The screenshot shows a test shot which was taken at ISO 6400, aperture f/2.8 and shutter speed of 1/8s. The final shot should be taken with ISO 100 and aperture f/8 aperture crop factor calculator, 2.5.3.1. Crop factor doesn't affect the focal length simply because the focal length of a lens is the only focal length of that lens as most lenses nowadays are designed to fit APS-C sensors in DLSRs which are marked with a true, actual focal length. 2.6. How do you calculate the equivalent focal length of a lens? 2.6.1

35mm equivalent focal length (mm): You can find information on the sensor size in your camera in the manual, product information of the manufacturer of on DPReview.com . More information on the how an why of the Lens Multiplication Factor (also referred to as 'Crop Factor') can be found on Wikipedi An equivalent exposure is one that relies on the same amount of light for the proper exposure but juggles the aperture and shutter speed settings to yield different image effects. This waterfall was photographed with two exposures, one at f/22 at 1⁄15 sec and one at f/8 at 1/125 sec

Equivalent Exposure Calculator Have you ever visited a website with an impressive CCD image and wondered what it would take to get that picture with your equipment? This calculator will give you the necessary exposure time with a given CCD and telescope needed to match that taken with another camera and scope Enter three values, the forth will be calculated. Aperture, ISO / ASA and exposure time can be set at the camera. EV means exposure value. Different lighting conditions require different EVs, the brighter, the higher is this value. A table with conditions and their approximate EVs is below the calculator As a calculator. The shutter, ISO and aperture gauges move to complement each other. The app remembers the gauges moved recently e.g. if you move aperture, then ISO, then aperture again, the app learns that ISO and aperture should be left where you want them, and shutter will move to complete the exposure The well-known American author, Bill Bryson, once said: Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness USING THE CALCULATOR. In order to calculate the depth of field, one needs to first decide on what will be considered acceptably sharp. More specifically, this is called the maximum circle of confusion (CoC), and is based on the camera sensor size (camera type), viewing distance and print size. The default is to say that features smaller than 0.01 inches are unnecessary, when viewed in an 8x10.

f/5.6 > f/8 > f/11 > f/16 = 3 stops reduction in light captured. ISO 400 > ISO 800 = 1 stop increase in light captured. Therefore, the net effect from aperture and ISO is 2 stops reduction in light. Now you need to increase the light captured by 2 stops to get the equivalent exposure The concept of equivalent exposure can be a tricky one to wrap your mind around when you're just getting started in photography. Photography enthusiast and animator Vincent Ledvina of Apalapse. Telescope Calculator Inputs: Scope Aperture: The diameter of a telescope's main lens or mirror — and the scope's most important attribute. Scope Focal Ratio (f/number): A lens or mirror's focal length divided by its aperture. For instance, a telescope with an 80-mm-wide lens and a 400-mm focal length has a focal ratio of f/5 Equivalent photos, as opposed to equal photos, are photos that have the same perspective, framing, DOF, shutter speed, lightness, and display dimensions.Equivalent lenses, then, are lenses on different formats that produce Equivalent images (same diagonal angle of view and same aperture diameter). Equivalence is only relevant when comparing different formats, comparing a crop with a wider. We make a list of open area calculation formular of perforated sheets with round, square, slot and hexagon holes in straight and staggered rows

If both the Canon lens and the equivalent third party lens have the same max aperture, their ability to autofocus with a 2x will be the same. If the third party lens had a wider max aperture compared with the Canon lens, then you aren't comparing apples to apples, in which case it's a bit pointless Similarly, the focal length multiplier relates the focal length of a lens used on a smaller format to a 35 mm lens producing an equivalent angle of view, and is equal to the crop factor. This means that a 50 mm lens used on a sensor with a 1.6X crop factor would produce the same field of view as a 1.6 x 50 = 80 mm lens on a 35 mm full frame sensor Online calculator to quickly determine Air Flow Rate through an Orifice. Includes 53 different calculations. Equations displayed for easy reference Find any point where there's a circle and you find an exposure combination of shutter and aperture. Follow the diagonal line and you can find equivalent exposures. For example, find the dot at F4 and 1/60. If you follow that diagonal line, you'll see that the other dots on that line indicate equivalent exposures Crop Factor and Aperture. Different sensor sizes change the field of view provided by a focal length. We refer to this as the crop factor, and it allows us to quickly determine that a 45mm micro four-thirds lens is equivalent to a 90mm full frame lens. While the crop factor works for determining the field of view, it does not work for.

Lumen Estimation Calculator. Knowing how many lamps you need to adequately illuminate a room or space can be tricky. In addition to the size of the space, a variety of factors, such as the activities being conducted and wall reflectance can also play a role Equivalent exposures Figure the equivalent exposure for each problem. You should find the shutter speed or the correct aperture. 1. f 5.6 @ 250 is equivalent to f 8 @ _____ 2. f 16 @ 30 is equivalent to f 11 @ _____ 3. f 4 @ 125 is equivalent to f 11 @ _____ 4. f 2.8 @ 500 is equivalent to f 16 @ _____. A smidgen means less than one-sixth of a stop. Note that because the standard aperture values, f/2, f/2.8, f/4, etc. don't go exactly in a geometrical progression, many settings which are equivalent for practical purposes are actually out by a smidgen. E.g. 1/100 at f/2.8 is slightly more than 1/50 at f/4 The net effect is that you lost one stop of light. To complement that, you can increase your ISO by one stop to ISO 1600. An image with settings f/4, ISO 800, and 1/15 second is an equivalent exposure to f/2, ISO 1600, and 1/125 second because they basically let the same amount of light into the camera

Exposure Calculator to Compare Any Two Camera Exposures

The Sunny f/16 Rule for Digital Exposure. The sunny f/16 rule, or Basic Daylight Exposure (BDE for short), tells you that the proper exposure in digital photography for a frontlit subject is f/16 with a shutter speed of 1/ISO (that's 1 over the ISO in use).According to the sunny f/16 rule, at ISO 100, BDE would be f/16 at 1/100 second, and at ISO 200, BDE would be f/16 at 1/200 second A lens that has an aperture range means that it has a different maximum aperture depending upon what focal length you're using it at. To use the Pentax 55-300mm f/4-5.8 lens pictured above as an example, when the lens is used at its 55mm focal length, you can use a maximum aperture of f/4. At the 300mm maximum focal length though, your. Visualize how hyperfocal distance changes with aperture and focal length. Quickly understand the relations among aperture, focal length and hyperfocal distance. Focal Length Match Calculator. Compute the equivalent lens focal length and aperture to produce the same field of view and depth of field between two cameras with different sensor sizes Hello everyone! Sorry for the delay with this video. I had finals and other things that caught up to me, but the next one should arrive on schedule. Comment. This is true and you can prove it mathematically. What he is saying is that a 50mm f/1.8 lens, when placed in front of a DX sensor, gives the equivalent field of view of a 75mm lens on a full-frame camera AND gives you a depth of field that is mathematically the equivalent of an f/2.7 aperture

The NA calculator calculates the equivalent f/stop for an objective, adjusted for the magnification at which it is being used. Uses working f/stop = Magnification / (2*NA)) where NA is numerical aperture of the objective. Infinite Objective Focal Length Macro Calculator In photography, the 35 mm equivalent focal length is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size.The term is useful because most photographers experienced with interchangeable lenses are most familiar with the 35 mm film format.. On any 35 mm film camera, a 28 mm lens is a wide-angle lens, and a 200 mm lens is a long-focus lens A Mesh to Micron Conversion Table can be made using this screen scale as its base with an opening of 0.0029 in. which is the opening in 200 mesh 0.0021 in. wire, the standard sieve as adopted by the Bureau of Standards of the U. S. Govt., the openings increasing in the ratio of the sq. root of 2 or 1.414 except in the sizes Nos. 65 to 200 which increase in the ratio of the 4th root of 2 or 1.189

But equivalent distances don't have to use the same aperture, a 150 mm lens at 18 feet can stop down a bit, say to f/3.5, which is same picture with twice the DOF span of 50 mm f/1.8 at 6 feet. That's still not much, but it's sure a lot better, where it counts German photography blog Photoblog. The final and correct shutter speed will be 1/15 of a second. This is a 4X or two stop change. Mathematically, to make a two stop change to the shutter, remember each change of the shutter is the equivalent of a 2X change. You need to do this twice for a 2 f/stop change; thus the change in shutter speed is 4X Crop Sensor (APS-C) Cameras and Lens Confusion Despite the fact that so called crop sensor digital SLRs have been with us since 1999 (the Nikon D1, with the Canon 30D following in 2000), there's still a huge amount of confusion out there about exactly what a crop sensor camera is and what effect is of using a lens with a crop sensor camera rather than a full frame camera

Pinhole Camera Aperture Chart. Calculating exposures for your pinhole camera can be difficult. The Lensless Camera Mfg. Co., whose models we sell, has provided us with the following table of apertures and f-stops for their products Using the Sunset 4 Rule, you would change your aperture of f/4 and maintain a shutter speed of 1/200 seconds and an ISO of 200. Again, you've simply increased the light allowed into the lens by opening the aperture by four stops. So, again, your settings on a sunny day would look like this: Aperture: f/16. ISO: 200. Shutter Speed: 1/200 second

1. Numerical Aperture The figure above depicts a section of a clad cylindrical fiber showing the core with refractive index of N1 and the clad with index of N2. Also shown is a light ray entering the end of the fiber at angle (A), reflecting from the interface down the fiber
2. It is equivalent to adjusting the f-number inversely in proportion to crop factor - a smaller f-number for smaller sensors (this also means that, when holding the shutter speed fixed, the exposure is changed by the adjustment of the f-number required to equalise depth of field. But the aperture area is held constant, so sensors of all sizes.
3. Focal length is focal length. so (provided it fits) ANY 75mm lens will give exactly the same FOV on a given aperture plate (i.e. film/sensor area) as any other 75mm lens. What you are confusing is the change in FOV between the 6by7 medium format camera and full frame camera for the same focal length
4. The new mirrorless medium format Fujifilm GFX system has really shaken the camera industry lately, and judging by the initial responses from photographers I know, this is a format and camera system that's going to be around for some time. There's never been a more affordable way to get into digital medium format photography before, and whilst Pentax paved the way over recent years with the.

The inverted-F antenna is shown in Figure 1. While this antenna appears to be a wire antenna, after some analysis of how this antenna radiates, it is more accurately classified as an aperture antenna. Figure 1. Geometry of Inverted-F Antenna (IFA). The feed is placed from the ground plane to the upper arm of the IFA Simply input your focal length, sensor size, and max aperture and we'll give you what the 35mm equivalent is of that configuration. 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 Receiver aperture size is an important parameter to optimize. Radiative and convective losses are essentially proportional to aperture area, for receiver temperature held constant, suggesting that this area should be minimized. On the other hand, a larger aperture will intercept more of the incident radiation so increasing the optical efficiency

For a 50 mm lens, an aperture diameter of 35.4 mm as in the example above is equivalent to an f-stop of 1.4. Instead of just the number 1.4, you will often find notations involving an f such as f/1.4 or simply f1.4. Also note that a large aperture diameter corresponds to a small f-number, and vice versa Equivalent Exposure. Think in terms of numbers. A value of 10 can be achieved by adding 2+5+3. An equivalent value of 10 can also be achieved by subtracting and adding 8-4+6. The same can be applied to exposure. An exposed value of f/8.0 at 1/15 sec with an ISO of 100 is equivalent to f/2.8 at 1/125 sec with an ISO of 100 The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe.. The table below can be used to compare equivalent diameters for rectangular and round circular ducts. The table is based on the ducts friction loss formula.. The rectangular dimensions and the air flow volume are adapted to the equal friction loss. At this point you have max sharpness (aperture), max dynamic range (ISO) and least noise (ISO). However a 1/250s exposure time is not much use for those silky water effects you require. You will need a shutter speed of 2 seconds or more for any sort of smooth blur effect. What sort of ND filter would we need to mount on the lens to go from 1. This resonant frequency calculator employs the capacitance (C) and inductance (L) values of an LC circuit (also known as a resonant circuit, tank circuit, or tuned circuit) to determine its resonant frequency (f). You can use the calculator in three simple steps: Input any two parameters for a resonant circuit

In general, this sweet spot is between two or three stops down from the maximum aperture. For example, for a lens that has a maximum aperture of f/1.4, the sweet spot normally falls between f/2.8 and f/4. For a lens that has a maximum aperture of f/4, it's between f/8 and f/11 Exposure Calculator is for photographers to calculate the equivalent exposures based on the current exposure values shown on your camera. You can edit the value of: - Aperture, Shutter Speed, ISO - EV - ND Filter *** Star Calculator! *** Star Calculator is for photographers capturing points of stars instead of star trails You enter your 4/3 len's focal length and aperture (f-stop) setting and click calculate to see what you are actually getting in the world of 35mm. Of course, what I really need to do is the other way around that's coming! This online calculator allows you to calculate the 35mm equivalent Focal Length for a micro 4/3 camera (eg Panasonic GH4 How do I calculate the aperture size and area, considering an 35mm equivalent focal length value and non-equivalent aperture f-number (in terms of exposure, no multiplication of the crop factor of the sensor).. For example, I have a 1.5x crop sensor. The lens is equivalent to 50mm in 35mm terms and the camera has an aperture of 2.8 Aperture (f-stops): Aperture refers to the size of the opening inside the lens that the light must go through to reach the film. Aperture is measured in f/stops as indicated in the series below: 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45. This looks tougher, but the solution is the same as for the shutter speeds.
