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.


Detailed

The 35mm equivalent lens is shown for reference. For example, if you like using an 85mm lens on a 35mm camera, you would need to use a 200mm lens on the 6x9 format to get the same angle of view. The 6x9 film gate size used for the calculations was 2.25 x 3.25 inches. The 35mm film gate size used was 24mm x 36mm.

Dec 02, 2019 · “35mm equivalent” is a phrase that often crops up when looking at the specifications of Digital Cameras and Lenses. So why the hangover from 35mm film days and why is there no new standard set of numbers for digital cameras to describe the sort of wide angle

That is, if they describe a camera as having a particular 35mm equivalent focal length, it means the camera produces the same field of view along the diagonal as a 35mm camera with a lens having the stated focal length. Other companies use the horizontal field of view rather than the diagonal field of view.


Detailed

With many smaller formats now common (such as APS C), lenses may be advertised or marked with their "35 mm equivalent" or "full frame equivalent" focal length as a mnemonic. This 'equivalent' is computed by multiplying (a) the true focal length of the lens by (b) the ratio of the diagonal measurement of the native format to that of the 35 mm format.

Feb 14, 2017 · This Crop Factor Calculator Makes Sensor Math a Breeze. mmCalc is a simple online tool that uses your sensor size to instantly convert any focal length and aperture f stop into its 35mm equivalent. Whether you’re using a Canon APS C camera (crop factor 1.6) a Nikon APS C camera (crop factor 1.5), an old Nikon 1 with a 1 inch sensor

Field of view (also known as FOV) The values for Field of View (FOV) come up frequently enough at the forums that I thought a list might be helpful for quick reference.. Remember that focal length is stated for infinity and most lenses decrease in focal length as you focus closer.


Detailed

The 35mm equivalent focal length of a lens is sometimes given for cameras using other film formats, and often for digital cameras. This is to give some comparison of the angle of view of lenses between different cameras with different film frame or digital sensor sizes. Typical 35mm format lenses standard lenses are between (approximately) 40 55mm. Telephoto lenses being longer, and wide angle being shorter.

Jun 12, 2016 · And because we know the crop factor, now we will be able to learn the 35mm focal length equivalent of iPhone's lens. To do that we will multiply the actual focal length of the lens by the crop factor. 4.67x7.21 equals 33mm. And this is the staple focal length value for shooting full frame and film.

May 08, 2001 · in 35mm. If the 110mm too costly, you may find a good lens in the 120mm area. One of the problems figuring focal length to focal length is the odd size of 35mm film. You have to figure for the wasted film at the ends of the 35mm size. If you like the wider lenses, 90 to 135 is a good choice. The 210mm gives good perspective with 4x5 and is


Detailed

Part of the confusion seems to be that you read the phrase 35mm equivalent and assumed it meant the focal length of the lens. In fact, that phrase simply refers to the 35mm camera format that started with the film cameras upon which DSLRs are based. The photographic film used in most film SLR cameras is called "35mm film" because it's 35mm wide.
