SLR Vs Mirrorless
For many years, photographers have assumed that, when it comes to image quality, full frame camera beats a camera equipped with a smaller sensor, including DSLR half frame.
The reasons in support of this view are several, starting with the fact that the full frame camera sensors have larger pixels (or photosites). This means that a full frame sensor creates images with less noise and better image quality overall.
Photosites larger also means greater light captured: the full frame cameras able to photograph without the aid of artificial light sources, where all the others can not.
The full frame cameras usually have more megapixels: although this does not matter to most photographers (indeed, many turn up their nose at the more megapixels means smaller photosites) http://akusaraprosound.com, can be useful if the user needs to make prints large.
There are many targets to choose from, the zoom lenses to the fixed focal lengths. There are also many manufacturers can offer a range of solutions for all requirements, needs above all portfolios.
Legacy lenses can be used without problems: if you have a goal of your old 24mm film camera, you can use it exactly the same way on a full frame camera (electronics separately). A very interesting solution whereas there are lenses of excellent workmanship made (and commercially available) to the old analog. Obviously a lens analog can also be used on a camera with smaller sensor but this means “stretch” (because of the crop factor) the focal length of the same (in the case of Nikon, in 24 mm would become a 25 × 1.5 = 36mm).
A full frame present a lower depth of field at any aperture and focal length compared to what we would get with a focal length for an APS-C (the half frame). For example, a photo taken at f2.8 with a 85 mm lens on a full frame camera has less depth of field in a photograph taken with f2.8 lens and a 50mm on an APS-C. This is a huge advantage, especially if you want to create photo with bokeh.
Very often the full frame are made of the best materials and are bright. A full frame “survive” more than to maintain a good economic value over the years: try searching on the internet is not just brand new models and compare them with the prices of the current full frame, you will not notice the abysmal differences as in the case of APS-C that in Within a couple of years they amuse “throwaway”.
