Real-world depth-of-field demonstration
| Format | Focal length | Equivalent aperture |
|---|---|---|
| Full Frame | 85mm | f/1.2 |
| APS-C | 56mm | f/1.8 |
| Four Thirds | 42.5mm | f/2.4 |
| 1″-type | 32mm | f/3.2 |
Is aperture different on APS-C?
At the same aperture and for the same field of view, an APS-C sensor will have a higher depth of field than with a full frame camera. A full frame sensor camera and lens will have less in focus for a given aperture and field of view than an APS-C combination, allowing more creative effects.
Does APS-C crop factor affect aperture?
This is because, like focal length, the aperture of the lens is also affected by crop factor. An aperture setting of f/4 on a full frame is equivalent to 4/1.6 = 2.5 (f/2.5) on an APS-C camera and 4/2 = 2 (f/2) on the micro four thirds camera.
What is 50mm on APS-C?
A 50mm lens on a camera with a 1.5x crop factor APS-C sensor gives a field of view equivalent to that of a 75mm lens on a full-frame or 35mm film camera.
What is the crop factor of APS-C?
A standard APS-C sensor (Fuji, Sony, Nikon DX) has a 1.5x crop factor, meaning if you divide the diagonal length of a full frame sensor by that of an APS-C sensor, you get about 1.5 (Micro Four Thirds has a 2x crop factor).
What is equivalent aperture?
In digital photography, the 35mm-equivalent aperture range is sometimes considered to be more important than the actual f-number. Equivalent aperture is the f-number adjusted to correspond to the f-number of the same size absolute aperture diameter on a lens with a 35mm equivalent focal length.
What is ISO equivalent?
In digital cameras, ISO speed is a number that indicates sensitivity to CCD or CMOS light. You might have heard of CCD and CMOS before – they are basically the digital equivalent of film in normal film cameras. ISO values come in numbers such as 100 and 400.
Is 75mm good for portraits?
On an APS camera, the 50mm is the equivalent of a 75mm, which is an ideal focal length for portraits. Not bad for a small, lightweight lens. The only disadvantage? When shooting close-ups, noses might look a bit larger than when using a true telephoto, which would compress the space for a more flattering shot.
What is a 50mm lens good for?
Why use a 50mm lens? No matter what type of photography you like, there’s a good chance you can use a 50mm lens. It’s one of the most popular lenses on the market, and it can be used for anything from portraits and car photography to landscapes and nighttime shots.
Is Super 35 the same as APS-C?
In the cinema world, the standard sensor size has developed around the Super 35 (3-perf 35mm) frame, which has a crop factor of approximately 1.5x compared to full frame. For people coming from the stills world, this is about the same size as an APS-C sensor capturing 16:9 video.
Is 50mm good for APS-C?
50mm lenses are good for APS-C cameras. They give the same field of view as a 75mm lens on a full-frame camera. This doesn’t flatten the image too much and with wide apertures – wider than f2 – you should get pretty nice bokeh as well.
When would you use a 75mm lens?
85mm (and 75mm)
85mm is considered a classic focal length for portraits — you’re far enough away to get a bit of perspective compression, but close enough for it to feel intimate.
Is a 50mm lens good for street photography?
The 50mm is the ideal street photography lens. Actually it’s an ideal lens full stop. It has the most applications of any focal and hence why they are often referred to as the “nifty fifty”, the versatile lens.
What is 28mm on APS-C?
A 28mm f/2 lens on APS-C is only theoretically equivalent to 42mm f/3 on full frame as far as angle of view and depth of field are concerned. It is equivalent to a 42mm f/2 as far as exposure (shutter speed, aperture and ISO) are concerned.
Why full frame is called 35mm?
The 135 film we used before the digital days has the width of 35 mm; thus the name 35 mm format. The Full Frame sensor which has vertical length of 24 mm and horizontal length of 36 mm gives the same frame/view as the 35 mm film camera when using the lenses of same focal length.
Can I use a full frame lens with an APS-C sensor?
Can full frame lenses be used on APS-C sensors? Generally speaking, yes- insofar as the mount is compatible. The glass in most full frame lenses is oversized compared to what is necessary for APS-C sensors, so as long as they are compatible with model and mount style it should work.
How do you calculate aperture equivalent?
Equivalent Focal Length = (Focal Length) x (Crop Factor) Equivalent Aperture = (F-Number) x (Crop Factor)
Is medium format better than 35mm?
Medium format gives far better technical quality than 35mm and is just as easy to use, since the film comes in rolls you can load in daylight like 35mm. Mamiya and Pentax and Contax make autofocus motordrive cameras and zoom lenses, so you have no excuses. Medium format is great for everything.
Is medium format better than full-frame?
Medium format resolution
Bigger sensors mean more space for pixels. Currently the largest full frame resolutions are between 50 and 60MP, while medium format offers 100MP and more, providing vast amounts of image data.
What are equivalent exposures?
Equivalent exposure is a term used to describe finding the right balance of a few factors (like ISO, aperture, and shutter speed) to create the right exposure for an image. When capturing a photo, this usually takes place by juggling things like aperture, the ISO, and shutter speed.
Is ISO equivalent to film speed?
Term: ISO (film speed)
Used colloquially in the context of film photography, ISO followed by a number (e.g., 400) represented the sensitivity of a given film emulsion to light, often referred to as “film speed.” Higher ISO numbers indicated a greater sensitivity to light.
