The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a lens focal length by the crop factor gives the focal length of a lens that would yield the same field of view if used on ...
Most consumer-level DSLRs, SLTs and mirrorless cameras use relatively large sensors, either somewhat under the size of a frame of APS-C film, with a crop factor of 1.5–1.6; or 30% smaller than that, with a crop factor of 2.0 (this is the Four Thirds System, adopted by OM System (formerly Olympus) and Panasonic).
The only place that section belongs in is a, "Problems with engineering a digital sensor" but this article is about "crop factor" not Digital sensors. Crop factor became an issue back in the fifties (1950s) when 135 format film hit the market and everyone thought it was just a play thing.
Many track and field statisticians use a conversion factor estimate of 0.24 seconds added to any hand-timed mark in the 100 m or 200 m event, and 0.14 seconds to any hand-timed mark in the 400 m or longer event: these conversion factors are only applicable for comparing marks from a variety of sources, and are not acceptable for record purposes.
The Henneke horse body condition scoring system is a numerical scale used to evaluate the amount of fat on a horse's body. It was developed in the early 1980s by Don Henneke at Texas A&M University with the goal of creating a universal scale to assess horses' bodyweight, [ 1 ] and was first published in 1983. [ 2 ]
A cotton picker at work. The first successful models were introduced in the mid-1940s and each could do the work of 50 hand pickers. Mechanised agriculture or agricultural mechanization is the use of machinery and equipment, ranging from simple and basic hand tools to more sophisticated, motorized equipment and machinery, to perform agricultural operations.

Equine drug testing is a form of drug testing applied to performance horses in regulated competition. Most common in racehorses , drug tests are also performed on horses in endurance riding and in international competition such as the Olympics and FEI -sanctioned competition.
This horse's dorsal stripe is most likely caused by non-dun 1. Less distinct primitive markings can also occur on non-dun horses, even in breeds which are not known to have any dun individuals. The most common primitive marking found is a dorsal stripe. [1] Most non-dun horses do not have darker primitive markings, but some do.
