Basically that pages shouldn't be created for them. Sorry that link should have gone here: Wikipedia:Avoid neologisms. Does anyone have any coment before I add it to the list for deletions? - Hmette 02:00, 22 March 2007 (UTC) Reply What's the policy on neologisms? Dicklyon 03:11, 22 March 2007 (UTC) Reply On further reflection - it may be that this article should be deleted on the basis that it comes under the category of neologisms.

In general this section makes assertions that are not sourced and more in tune with debate across discussion forums rather than ascertainable technical or objective facts. Their newly released model, the Canon EOS 5D, seeks to emulate that success at a much lower price point.' ![]() The company that has had the most success with full-frame sensors is Canon Inc., whose full-frame sensor cameras have been very successful in the high-end professional photography field. Eastman Kodak produced three models of full-frame camera, but all are now discontinued. The first, fairly unsuccessful attempt was by Contax with a Philips sensor Pentax worked with this sensor as well, producing a prototype MZ-D, but abandoned it before production. While a digital camera for any format could be full frame, in practice most examples produced have been for 35mm format. A smaller image sensor stays within the "sweet spot" of the lens and sensor combination with less difficulty. Adding to this, lenses tend to produce poorer results towards the edge of the circle in any case. Thus, the sensor will be less sensitive to light towards the edges of the image circle, where the light rays are likely to be further from perpendicular. The secondary reason is that digital imaging chips tend to have a much narrower range of acceptance angles than film. Moore's law does not apply here most of the semiconductor industry's advances in affordability have been driven by the ability to make circuits smaller and smaller, but an imaging chip must remain large, and such large chips get cheaper only slowly. As chip sizes get larger, the yield gets drastically lower and thus the prices higher. The chief reason that digital SLRs have not been full frame is to do with the cost of producing such large sensors. In practice, however, the term is often used to simply mean a camera having a sensor the same size as a full 35mm frame, while the applicability of the term to four thirds system cameras is a matter of much, often heated, debate. Similarly, a camera using a hypothetical new mount system and featuring a 24mm x 36mm sensor (the size of a 35mm film frame) would not be full frame. It follows from the above definition that cameras using a lens mount that was designed for digital SLRs (such as the Olympus Four Thirds System) are not full frame cameras. The article has been amended accordingly. This distinction not applicable to other systems such as Nikon or 4/3 where the lenses are designed for the particular size sensor, and therefore use the "full frame" of the image circle. The term "full-frame" is controversial in that it only applies where a range of lenses are designed for a sensor that is equivalent in size to a 135 film negative, but also compatible with smaller sensors, except that the image is "cropped". ![]()
