Live preview

Historical Background
While some types of digital cameras trace their origin to a corresponding type of film cameras (eg cameras digital single-lens reflex digital reflex "to the film single lens reflex" SLR " digital rangefinders rangefinders movies, etc), cameras with live preview also derived from electronic (video) TV cameras.
Until 1995, most digital cameras do not have a live preview, most digital cameras single lens reflex still do not have this feature, because it is fundamentally incompatible with the swaying mirror single-lens reflex mechanism. The first digital cameras with an LCD screen and live preview were Casio QV-10 and a Ricoh RDC-1995. The first digital SLR to use the live view was fixed lens Olympus E-10, since 2000, the first interchangeable-lens digital SLR to use the live view was the Canon EOS 20Da, a special version of the Canon EOS 20D and modified for astrophotography. The first general purpose digital SLR lens interchangeable with live view was the Olympus E-330, 2006.
Compact and bridges, the low and high-end cameras with live preview
Live-preview cameras include two different categories, but not so different: Bridge digital cameras and compact digital cameras. Bridge cameras are generally higher and range Advanced (full featured), high (better quality of construction) and significant covenants.
Digital SLR cameras, usually without hearing live preview
When considering the advantages and disadvantages of digital SLR, the comparison is usually among the best bridge camera, and the smallest and cheaper DSLR, so most of what can be said on this subject is discussed in the article bridge camera. Check in particular sections following this article:
A single fixed lens, but versatile
LCD as main display EVFs
A comparison between the compacts and digital SLRs It would be a really a very contrasted in terms of size, weight, price, capacity and image quality.
Almost all the bridges modern and compact cameras have a movie mode, while DSLR not offer this option until the Nikon D90 was released in August 2008. SLRs have faster performance than cameras other in many areas (for example, start-up time, shutter release time lag, continuous mode, auto focus), which is not a feature of type digital SLR, but simply the enhanced functionality of more expensive models of cameras. Consequently DSLRs are more suitable for situations such as sports or action photography, where a fraction of a second delay between pressing over the trigger and exposure can result in failure at the right time. Cameras with larger sensors work better than cameras with smaller sensors in low light with less noise in the optical image; SLR digital sensors are larger than most digital SLR cameras do not, resulting in better images. No DSLR digital cameras with large sensors are available, such as the Sony R1, Sigma DP1 and Panasonic Lumix DMC-G1/GH1.
Digital SLR with Live Preview
Live-preview functionality is becoming more and more common in digital SLR cameras, and from mid-2008 almost all new digital SLRs have the feature. The following is a partial list of the DSLR with live preview:
Canon 20Da, 40D, 50D, 450D, 500D, 1000D, 1D Mark III, 1Ds Mark III, 5D Mark II, 7D, 1D Mark IV
Leica Digilux 3
Nikon D90, D300, D300s, D700, D5000, D3, D3x
Olympus E-10, E-20, E-330, E-410, E-420, E-450, E-510, E-520, E-620, E-30, E-3
Panasonic DMC-L1, DMC-L10
Sony Alpha A300, A330, A350, A380, A500, A550 and
Pentax K20D, K-7, Kx
Samsung GX-20
Live preview in some or all of these cameras is not conventionally generated (The image formed by the lens, either directly or not is not continuously projected onto the main sensor). Also Live Preview in DSLR these rarely serve as the primary means of developing and previewing before taking a photograph. (In SLRs, have an optical view reflected in the OVF (optical viewfinder) for that purpose and live preview is an additional feature).
While preview technology has advanced, and that by March 2008, there are digital SLR preview live as perfectly as a fixed lens camera. The main issues are with the slow focus and lack of exposure-priority screen. Among the digital SLR that achieve the standard approach through the detection phase sensor used by digital SLR, none has demonstrated 100% coverage as conventional digital cameras, thereby eliminating the key advantage of the light live preview for optical viewfinders. In addition, a 100% coverage optical viewfinders have become more common and affordable with the advent of the Nikon D300, Olympus E-3 and the Pentax K-7.
