35mm Equivalent Focal Length
Focal lengths of digital cameras with a sensor smaller than the surface of a 35mm film can be converted to their 35mm equivalent using the focal length multiplier.

35mm Equivalent Focal Length
The size of the image sensor varies from model to model even from the same manufacturer. So if you see a figure like 7.
35mm Equivalent
This is one of the specifications of a digital camera and relates to how it reproduces the 35mm format of traditional film cameras. This is often listed as a range of focal lengths for lenses.
35mm Equivalent
Because of the relative novelty of consumer digital imaging technology, Canon has begun providing the equivalent focal length in traditional 35mm film cameras.

Using "35mm Equivalent" focal lengths, a 35mm-50mm lens is considered normal (35mm is a slight wide-angle, but pretty much the norm in today's P&S cameras), a 28mm or less is a wide-angle, a 100mm-200mm is a medium telephoto, ...
You should be aware that lenses for digital cameras are often referred to in their "35mm equivalent" focal lengths rather than their actual physical focal lengths.
FOCAL LENGTH ("35mm EQUIVALENT")- The lens in a digital camera is almost always smaller than in a 35mm SLR (single lens reflex) camera. Because of that the actual focal lengths mean little to those who are already familiar to photography.
Digital cameras cost three to four times more than their 35mm equivalent. Canon EOS Digital Rebel for instance, costs four times more than the EOS Rebel Ti 35mm version.
If a subject is captured with a 50mm lens (35mm equivalent) we experience a more natural perspective than if it is captured with a wide-angle or tele lens.
Most digital cameras have their widest focal length around 35mm equivalent, some go as wide as 28mm equivalent (which is as wide as you'll need for day-to-day use), some only go as wide as 39mm equivalent (a little zoomed in for most people's taste, ...
The crop factor is most often used to determine the "35mm equivalent" field of view for any given lens when used on a camera with a sensor smaller than 24X36mm. As an example a 24mm lens on a 1.
I was intrigued by the previously introduced $760 model 8400 because its built-in lens covers the 35mm equivalent of 24 - 85mm. Getting as wide as 24mm directly in a fixed-lens zoom camera is unique.
As the article indicates, if you use a given lens on a smaller format, depth of field is reduced and the angular coverage ("effective 35mm equivalent focal length) decreases.

8 mm, or in 35mm equivalent: 24 to 60 mm. Combined with its large maximum aperture of f/2 - f/2.8 throughout the zoom range and an optical image stabilizer, this results in a very useful wide-angle zoom.
I like to think in terms of 35mm equivalent when shooting with these format cameras, so this, all in one, zoom lens plays out at from wide angle 27mm to telephoto 300mm. With that in mind I was surprised as to how compact and light this lens felt.
You'll sometimes see phrases such as "full frame equivalent" or "35mm equivalent" in conjunction with lenses designed for subframe sensors, such as EF-S lenses.
Multiplying the focal length to obtain the "35mm equivalent" before dividing to get the inverse for your maximum acceptable hand holding shutter speed seems prudent even though you likely can go beyond it if you have steady hands and often could ...
A wide-angle lens with a 35mm equivalent of 34mm was used to bring as much of the foreground in as possible. This was also set to f/11 to get sufficient front to back focus.
As a general rule, you should not allow this to fall to a speed slower than the reciprocal of your 35mm equivalent focal length.

Angle of View. This is calculated by the focal length of the lens and the size of the image sensor. The 35mm equivalents differ according to the sensor size.
Look for the "35mm equivalent" rating to get a better idea of your camera's range. Most fixed-length lenses on digital cameras fall somewhere between wide-angle and normal focal length.
The Panasonic 8mm fisheye is a fixed focal length lens, where the Tokina is a zoom lens. When compared to the Tokina at 10mm, they both have the same 180 degree angle of view diagonally, and the same 35mm equivalent focal length.
All digital camera manufacturers states this "35mm equivalent" focal length because people are familiar with this term and know what kind of image a 28mm lens produces compared to a 50mm lens, some common lens sizes (focal lengths): ...
You should pick ranges that suit your personal needs (careful: some Point and Shoot cameras are specified with 35mm equivalents in mind).
You might also want to modify the f-stop parameters (its the range I use mostly).
APS film and digital camera CCDs are smaller than conventional 35mm film so the indicated focal lengths are also smaller and should not be compared directly. For a direct comparison of APS and digital lenses look at the 35mm equivalent figures that ...
With a 50mm lens, a shutter speed of at least 1/50sec should be used. A 300mm lens will need a faster shutter speed of 1/300sec. The 35mm equivalent focal length should be used, see page 38 for more on lenses.
Speaking of monitors, larger ones are all in vogue this year with the size champ currently on the Samsung Pro 815 - 3.5 inches. This camera also comes equipped with a very long-range zoom lens, 28-420mm (35mm equivalent) but sadly no image ...
